CONRAD JOHNSON  CA150         LISTINO UFFICIALE   €. 7.940,00        Per offerta  e  promozioni Telefona /e -mail

Amplificatore Integrato stato solido a Mosfet da 135W per canale. Il CA150 combina la circuiteria dell'amplificatore di potenza MF2275 e un controllo divolume che utilizza un Burr-Brown sulla preamplificazione, eliminando lanecessità (e le distorsioni e le perdite) create dai cavi di interconnessione trapreamplificatore e amplificatore. Con il pieno controllo remoto di tutte le funzioni e 7 ingressi di linea, il CA150 offre tutta la flessibilità di un preamplificatore separato e con una potenza nominale di 135 watt /canale, il CA150 è in grado di pilotare la maggior parte dei sistemi di altoparlanti. Caratteristiche: Potenza: 135 watts Watt per canale da 20 Hz a 20 kHz a non più del 1% THD, entrambi i canali su 8 Ohm; sensibilità: 2.0V a potenza nominale; Risposta in frequenza (a 10 Watt): 20 Hz a 20 kHz, +/- .5 dB; Ronzio e rumore: 100 dB sotto potenza nominale; Impedenza di ingresso: 10k Ohms; dimensioni: (P x L x A) 37,1 x 48,3 x 11,4; Peso netto: 15 Kg

CA150 Solid State Control Amplifier The CA150 control amplifier represents a distinctly different approach to high-performance home audio. In many ways it is the ultimate embodiment of our corporate design philosophy that simple circuits yield best results. Similar in function to an integrated amplifier, a control amplifier offers the significant potential improvement of eliminating extra connections, external cabling, and inter-device connection considerations that limit conventional audio systems. But the control amplifier also eliminates an entire stage of audio circuitry (the line stage) and its inherent colorations. The CA150 audio circuit is similar to our highly regarded MF2550 and MF2275 power amplifiers, with FET voltage gain circuit for tube-like transfer function and a high-current bi-polar output stage to achieve a high damping factor with limited negative feedback. The CA150 adds a sophisticated level control circuit that allows for precisely repeatable level and balance settings made in 1.0 dB increments. Most integrated amplifiers not only forgo the advantage of eliminating redundant circuits, but also are cheapened by stripping out features and sacrificing parts quality to offer a low cost entry into a prestigious brand, thereby failing to achieve even the performance gains that could be afforded by integrating preamp and amp into a single package. By contrast, the CA150 is a full featured control unit with seven line-level inputs including a theater loop, and its circuits incorporate the kind of top quality parts for which conrad-johnson is known. All resistors in the audio circuits and related power supplies are precision metal film types. With the exception of the large power supply reservoir capacitors (which are specially chosen electrolytic capacitors bypassed by polypropylenes), all capacitors in these circuits use polystyrene and polypropylene dielectrics. The over-sized power transformer would not seem out of place in an amplifier with much higher power rating. Even the machined gold-plated connectors have been selected for their sonic-excellence. The use of carefully selected, high-quality parts enables the CA150 to properly exploit the dramatic potential of a control amplifier to enhance the immediacy of musical experience afforded by fine recordings. As a result, the CA150 is notable for its resolution of subtle dynamic shadings and palpable imaging, for a natural harmonic tonality, and extraordinary resolution. Those who wish to take the experience a step further will want to investigate the upgraded CA150SE, which benefits from a massive dose of CJD Teflon Capacitors and ultra high-performance metal foil resistors. Either model is sure to rekindle your passion for enjoying great music in your home  Specifications Power 135 watts per channel RMS both channels driven into 8 ohms from 20Hz to 20KHz at no more than 1% total harmonic distortion or intermodulation distortion. Small Signal Distortion less than .1% at mid-band Frequency Response (at 10 watts) 20 Hz to 20 kHz, +/- .5 dB Hum and Noise 100 dB below rated power Input Impedance 10k Ohms Phase speaker output is phase correct, sub-woofer output is phase correct Dimensions 14.625″D x 19″W x 4.5″H Weight 33 lbs.

Classic-2 Vacuum-Tube Preamplifier For more than thirty years, conrad-johnson has refined the concept of high end audio through its relentless pursuit of excellence. For as long as the company has been producing its world-renowned state of the art audio instruments, it has also been adapting the technologies and construction techniques responsible for those products and applying them to more affordable components designed for the music-lover who requires musically satisfying performance but whose budget does not encompass the loftiest of current offerings. The conrad-johnson Classic-2 vacuum-tube preamplifier honors this thirty-year heritage of musically accurate, moderately priced preamplifiers which have displayed the conrad-johnson name. The Classic-2 faithfully reproduces the harmonic structure of complex musical passages, preserving the distinctive tonal character of each instrument and voice. The space of the sound stage and the ambience of the concert hall are conveyed in realistic, three dimensional perspective. Individual instruments are precisely located within that three dimensional space. Musical transients are reproduced naturally, with realistic impact, but without the artificial enhancement which characterizes so many “hi-fi” components. Never imposing its own distractions, the Classic-2 invites the listener to enjoy the musical performance. The Classic-2 preamplifier is available as either a line-stage, or with an optional phono stage. Both stages are zero-feedback circuits. The phono section uses two triode amplifiers separated by a passive RIAA equalization network. The second triode amplifier is direct coupled to a high-current output stage. The line-level section has a single triode amplifi­er also direct coupled to a high-current output stage. These output buffer stages minimize the output impedance, making the Classic-2 compatible with nearly all installations, including those requiring long lengths of interconnect cable. DC plate voltages are supplied by a very low impedance discrete regulator, designed to prevent the power supply from imposing its own colorations on the audio signal. A regulated filament supply further isolates the unit from ac line voltage fluctuations Premium quality component parts are specified for the Classic-2 to assure full realization of the potential performance of the circuit designs and to dependably sustain that performance for years to come. Precision, metal-film resistors yield low noise performance for greatest clarity. Polypropylene and polystyrene capacitors, used exclusively in both the audio circuits and the regulated plate voltage supplies, offer maximum temporal accuracy. Phono equalization in the Classic-2 is accomplished with 1% tolerance precision parts to assure tonal neutrality. Industrial quality controls offer extended life and maintain a crisp, precise feel. The Classic-2 offers an excellent, low-cost introduction to the joys of modern tube preamplifiers. For those who wish to take the experience a step further we offer the upgraded Classic 2SE, which incorporates CJD Teflon Capacitors and ultra high-performance metal foil resistors in strategic applications in the circuit. Either model is sure to enhance your enjoyment of playing back great music recordings in your home.Classic-2 Preamplifier Specifications Gain: 27 db Maximum output: 9.5 Vrms Distortion: less than .15% THD Bandpass: 2 Hz to more than 100 KHz Hum and Noise: -98 dB relative to 2.5 V output Tube complement: 1 x 6922  Optional Phono Stage Gain: High Gain 54 dB, Low Gain 40 dB Phono Equalization: within +/- .25 dB of RIAA standard Hum and Noise: Phono Stage 80 dB relative to 10 mV input Tube Complement: 3x 12AX7 for High Gain, 2x 12AX7, 1x 12AU7 for Low Gain Dimensions 13.625D x 19W x 3.625H inches Weight 14 lbs. net 3-Year Warranty All conrad-johnson products are carefully hand assembled and each is thoroughly tested to assure conformity to our exacting performance standards.

ET3/ET3SE Vacuum Tube Preamplifiers At conrad-johnson, development of our flagship products has traditionally led to important enhancements of our entry-level offerings. The ET3 preamplifier is a case in point. The ET3 line-stage is a “baby” version of our flagship line-stage preamplifier, the GAT. The family resemblance is much more than skin deep. With voltage gain provided by a triode vacuum-tube, the zero-feedback line-stage circuit of the ET3, along with its DC voltage regulators, closely replicates the circuit of the GAT. Finally, and especially noteworthy, the ET3 features a relay operated discrete stepped attenuator level-control circuit of the type found in the GAT and CT5, absent only the balance control function found in those more costly models. Functionally, the ET3 provides highly flexible I/O facilities with six separate line-level inputs (including one “tape” loop), plus a theater loop that facilitates use in a home theater system. In addition, the ET3 offers the convenience of infrared remote control of all functions. For vinyl enthusiasts, the ET3 is optionally available with a vacuum-tube phono stage that borrows its zero-feedback audio circuit from our reference quality TEA1 phono stage. Customers can choose between high gain (recommended for cartridges with a rated output of 1.0 mV or less) and low gain (recommended for cartridges with rated output greater than 1.0 mV) versions of the phono stage. Input resistive loading is switch selectable over a range from 47 kOhms down to 200 Ohms. The ET3 phono stage is built to the same high quality standard found in the ET3 line-stage. Premium quality component parts are specified to optimize performance and to sustain that performance for years to come. Precision, metal-film resistors yield low noise performance for greatest clarity. Polypropylene capacitors, used exclusively in the audio circuits and the regulated plate voltage supplies, offer extraordinary temporal accuracy. In fact, the ET3 is built to standards that meet or exceed those of many companies’ “flagship” offerings. Those who wish to take the performance to yet a higher level will be thrilled by the availability of an upgraded “SE” version. The ET3SE boasts CJD Teflon capacitors in critical circuit applications, dozens of upgraded metal foil resistors (including ALL resistors in the stepped attenuator level control), upgraded machined input/output connectors, and even an upgrade AC mains line-cord. It would be fair to say that the only thing “entry-level” about the ET3 is its price. Arrange to audition one at a conrad-johnson dealer to find out for yourself – you’ll be surprised at just how affordable true high-end performance can be.

ET5 Enhanced Triode Preamplifier Introduced in 2009, the GAT Preamplifier continues conrad-johnson’s dominant position atop the rankings of reference preamplifiers. An important benefit of pursuing state-of-the-art designs is that the circuits and techniques developed in our flagship products are frequently directly applicable to our entire line of products. In this instance, we have embodied the technology of the GAT Preamplifier in the more cost effective ET5 enhance triode line-stage preamplifier at a more affordable price. The circuitry of the ET5 follows closely that of the GAT line-stage preamplifier. The audio circuit is elegant in its simplicity. An audio amplifier stage consisting of a single-ended triode amplifier provides the voltage gain. This amplifier stage is connected to the preamplifier outputs through a high-current MOSFET buffer, which achieves a very low output impedance, making the ET5 extremely flexible in the choice of interconnect cables and amplifiers. DC voltage is supplied to the circuit by our latest discrete voltage regulator that isolates the audio circuit from the power line by maintaining negligible impedance across the audio frequency band. Infra-sonic noise is minimized by operating the tube filaments (heaters) on a dc voltage supplied by a separate regulated power supply. The ET5 is also notable for convenience and ease of use. The unit features input selection and level adjustment by microprocessor-controlled relays, with controls available both at the front panel and via a full-function remote. All control functions of the ET5 operate through microprocessor-controlled relays. For the level control, the relays select combinations from a network of precision, low-noise metal foil resistors to effect loudness and balance changes in 100 steps of approximately .7dB per step. All switching and adjustment can be controlled by the unit’s remote control. A Theater Mode, which passes the input signal through at unity gain, makes it simple to incorporate the ET5 into a high quality home theater system without compromising its two-channel performance. Like its bigger brother, the GAT, the ET5 is constructed from the highest quality, carefully selected parts for unrivaled sonic performance and reliability. Tubes have been carefully hand selected for minimum noise and microphonics. The same CJD Teflon capacitors that distinguish the GAT are used in the ET5 for output coupling and post-regulator power supply storage. All other capacitors in the audio circuits and related power supplies are polypropylene or polystyrene – there are no electrolytic capacitors in the audio related circuits. The resistors in these circuits (including the two dozen level control resistors) are special low inductance, high-precision laser-trimmed metal foil resistors. Switches are sealed relays with gold-plated silver contacts. Input and output connectors are premium quality custom machined parts.

GAT Preamplifier The GAT Preamplifier embodies conrad-johnson’s latest advances in line-stage preamplifier technology. We believe that it will quickly be recognized as the new industry-wide reference standard for line-stage preamplifier performance, a role filled for more than a decade by its legendary predecessor, the ART preamplifier. Like the ART, the GAT Preamplifier will be available in a numbered, limited edition of 250 units which will be sold through selected conrad-johnson dealers. The GAT Preamplifier is a vacuum-tube, line-stage preamplifier that looks as good as it sounds. It is also notable for convenience and ease of use. The unit features input selection and level adjustment by microprocessor-controlled relays. Level and balance can be adjusted in 100 steps of approximately .7 dB per step. All functions can be controlled by the hand-held wireless remote control. The circuitry of the GAT Preamplifier is elegant in its simplicity. The audio circuit consists of a single amplifier stage incorporating one composite triode comprised of paralleled sections of a high-transconductance miniature dual triode vacuum tube. This amplifier stage is coupled to the preamplifier outputs through a high-current MOSFET buffer, which achieves a very low output impedance, making the GAT extremely flexible in the choice of interconnect cables and amplifiers. DC voltage is supplied to the circuit by our latest discrete voltage regulator that isolates the audio circuit from the power line by maintaining negligible impedance across the audio frequency band. Infrasonic noise is minimized by operating the tube filaments (heaters) on a dc voltage supplied by another discrete regulated power supply. Considerable care and attention have been paid to the physical aspects of the design as well. Microprocessor controlled relays, used for selecting sources and level setting, are located right at the input connectors, keeping signal paths short to minimize crosstalk between channels and inputs. The vacuum-tubes are isolated by a suspension system designed to minimize microphonics. The dramatic casework features attractive clear Lucite tube guards outside the chassis, allowing for easy access for tube replacement. At conrad-johnson we have long appreciated that the full potential of any circuit can only be realized by using the finest available parts. Each part for the GAT has been selected on the basis of both sonic performance and durability. The audio circuit (including the level control) is executed entirely with precision metal foil resistors and proprietary CJD Teflon capacitors. Tubes have been carefully hand selected for minimum noise and microphonics. The dc regulated power supplies use the same quality resistors as the audio circuits. Capacitors for the power supplies are exclusively polypropylene and Teflon – there are no electrolytic capacitors in the audio circuits or their related power supplies. All signal switching is done by special relays designed for signal applications. These relays are sealed and have gold plated silver contacts. Input and output connectors are machined from oxygen free copper, and are gold plated.

The TEA-2 triode equalization amplifier is a vacuum-tube phono stage offering an extraordinary degree of musical accuracy at a moderate price. The audio circuit of the TEA-2 is comprised of two cascaded single-ended triode amplifiers. The circuit is a zero-feedback design, to eliminate the temporal inaccuracies that negative feedback introduces. RIAA equalization is established by a passive network between the two gain stages. This network has been carefully designed and has been implemented with precision (1% tolerance) parts to precisely track the prescribed RIAA equalization curve assuring absolute tonal accuracy. Careful implementation of this fundamentally simple circuit results in extremely wide bandwidth, and low distortion, without resorting to negative feedback. A high-current MOSFET buffer stage follows the second gain stage to achieve a low output impedance (less than 200 Ohms). In the TEA-2, discrete regulated power supplies, carefully designed for minimum impedance, even at the highest audio frequencies, isolate the amplifier stages from the ac line and from each other to guarantee that power supply irregularities do not degrade the audio performance. The TEA-2 is available in high-gain (55 dB) and low gain (40 dB) versions to match a wide range of modern phono cartridges. The high gain version is recommended for use with cartridges with a rated output of 1.0 mV or below. The low gain version is best suited to higher output cartridges. Both versions offer switch selectable resistive loading allowing the user to fine-tune performance to the chosen phono cartridge. The performance of any audio component is only as good as its component parts. The audio circuits and the related regulated power supplies of the TEA-2 use polypropylene and polystyrene capacitors and precision metal film and metal foil resistors exclusively. All parts in the TEA-2's RIAA compensation network are 1% tolerance, to assure precise tracking of the RIAA curve. Input and output connectors and even hook-up wiring have been carefully selected for audio performance.  Specifications  Gain:  Low Gain - 40 dB  High Gain - 55 dB  Overload:  Low Gain - 175 mV  High Gain - 50 mV  Hum and Noise:  Direct Inputs - 80 dB below 10 mV input  Phase:  phase correct  Ouput Impedance:  below 200 ohms  Dimensions:  13.625"D x 19"W x 3.625"H  Net Weight:  14 lb

CONRAD JOHNSON  ET250S     LISTINO UFFICIALE   €. 13.500,00          Per offerta  e  promozioni Telefona /e -mail

Amplificatore di potenza stereo ibrido 250W. Caratteristiche: Potenza: 250 Watt  per canale da 20 Hz a 20 kHz a non più del 2% THD, entrambi i canali su 8 Ohm, o 400 watt per canale a 4 ohm; sensibilità: 1.85V a potenza nominale; Risposta in frequenza (a 10 Watt): 20 Hz a 20 kHz, +/- 0,25 dB; Ronzio e rumore: 104 dB sotto potenza nominale; Impedenza di ingresso: 100 kOhm; Valvole: 2 x 6922; dimensioni: 41 x 48,3 x 18,26 cm; peso: 29,5 Kg.

The ET250S is a 250-watt per channel stereo power amplifier, the MET150 a five-channel amplifier rated at 150 watts per channel. These sophisticated zero-feedback amplifiers offer the refinement of a vacuum-tube amplifier with the guts and control of a solid-state amplifier. Zero Feedback. Negative feedback is an engineering technique used to reduce measured distortion. While feedback does achieve this goal, it also introduces aberrations in the tran­sient response characteristics of the circuit. We have found that eliminating loop negative feedback can result in much finer gradations in dynamic response (micro-dynamics) and more accurate decay on musical transients. But eliminating negative feedback requires much more care in the design of the circuits—both in choosing devices and in power-supply design—and places greater demands on the parts. The Right Device for the Job. A power amplifier has two distinctly different functions. First, a voltage gain stage must increase the amplitude of the input signal by a factor of about thirty. The distortion characteristics of the amplifier are dominated by this stage. No device is better suited to accurately amplifying signals at high amplitude than triode vacuum tubes. For our enhanced triode amplifiers, voltage gain is provided by a 6922 vacuum tube, selected for its ability to track a high amplitude signal accurately. Theory and 30 years of experience have taught us that the voltage gain stage of a power amplifier dominates the sonic character of the critical mid-range of a power amplifier, and indeed these amplifiers exhibit the smooth, lucid midrange for which tube amplifiers are so highly esteemed. The high amplitude signal produced by the voltage gain stage must then be efficiently coupled to the loudspeaker system through an output stage to produce the power and control needed for a musically accurate response – basically to provide current gain and a low output impedance. High-current bi-polar devices have been specified for the output stages of these amplifiers, based on their extremely low output impedance and their ability to handle a great deal of current. This contributes the fast, weighty bass and seemingly limitless power reserve that are notable in these amplifiers. Solid Power Supplies. Rock solid power supplies are needed to enable the audio circuits to reach their potential on musical transients. The ET amplifiers feature oversized main power transformers (so that the circuits are not starved for current), and massive power storage reservoirs with high-speed capacitor shunts to deliver quick, even startling transient response. Carefully designed DC voltage regulators isolate the critical voltage gain stages to prevent demands of the output stage from modulating the input signal. Quality Parts. Conrad-Johnson components are internationally known for the quality of their parts, and the ET amplifiers are no exception. The audio circuits and their related power supplies utilize precision low inductance laser-trimmed metal foil resistors. The circuits employ polypropylene, polystyrene and Teflon capacitors extensively, except in the main power supply storage, where high-speed electrolytics are used because of the extremely high capacitance required. Precision-machined input/output connectors have been carefully selected for optimal sonic performance. Even the internal wiring is chosen on the basis of its sound quality in its specific application. Thoughtful engineering, specification of top quality component parts, and painstaking care taken in production make the MET150 and ET250S capable of extraordinary performance in music reproduction. We invite you to arrange an audition with your conrad-johnson dealer to confirm for yourself the extraordinary musicality of these amplifiers.

MF2550 and MF2275 Solid State Amplifiers At conrad-johnson we have a simple formula for achieving highly accurate, highly musical amplifiers: straight-forward, simple circuits designed for linear operation without excessive loop inverting feedback exceptional component parts selected for their ability to provide uncolored accuracy in music reproduction Straightforward circuits provide simpler, more direct signal paths and require fewer component parts to implement. This is desirable because all component parts fall short of ideal and impose limits to transparency. Fewer parts means less of the unavoidable coloration that is imposed by each part, even the best available. Fewer parts means that the budget can be concentrated to obtain the often costly best available parts especially for key circuit applications. The design of limited feedback circuit demands discipline from the circuit designer in developing a circuit in which each stage functions linearly without requiring external correction from a feedback loop. Our latest solid-state amplifiers, the MF2550 and MF2275, nicely embody this approach. Differing primarily in power output rating, these amplifiers share a common circuit design. High voltage FETS permit highly linear operation of the critical first voltage gain stage, while bi-polar transistors are used to configure an output stage with low output impedance to deliver maximum current to reactive speaker loads. Linear operation of the audio circuit requires a power supply designed to maintain absolutely fixed operating voltages while meeting current demands that fluctuate rapidly with the music itself. This imposes on the power supply similar design and component choice requirements as on the audio circuit itself. These amplifiers feature discrete dc regulators to power the critical voltage gain stage. The power supplies and grounds for the input and output stages are run by separate power transformer windings to isolate the input stage from the effects of the substantial current flows required in the output stage. Circuit design is a combination of science and art. At every step consideration must be given to how a circuit will be implemented. The realized performance will depend critically on the selected component parts. Conrad-Johnson products are known for unmatched quality of parts with custom-made film capacitors and precision metal film and metal foil resistors. We even use large 30 micro-Farad polypropylene capacitors for critical circuit applications where other designs commonly use non-polar electrolytic capacitors, the factor of 1000 reduction in dielectric absorption of polypropylene resulting in a cleaner sound. The power supply electrolytic capacitors are bypassed with high quality polypropylene film capacitors that provide a small but quicker responding current reservoir. For those wishing to take the musical experience a step further there are available special “SE” versions of these amplifiers which achieve further refinement in imaging, focus, and detail by upgrading a dozen or more critical capacitors to our proprietary CJD Teflon hybrid capacitors and a couple of dozen resistors to precision metal foil types. Our obsession with parts quality extends to the connections within the circuit itself. Power supply, signal and ground traces and wiring are parts of the circuit with limitations and shortcomings that must be accounted for. To enable the output stage to deliver substantial bursts of current, the layout provides storage capacitors close to each output device. The internal power supply connections and ground returns between the main supply and these local storage depots are accomplished with heavy, audiophile grade multi-stranded wire in order to minimize the impedance of these longer runs.

Classic Sixty Vacuum-Tube Amplifier Tasked with developing the most cost effective amplifier that we could build, consistent with our standards of quality of construction and performance, the conrad-johnson design team turned to our flagship product for inspiration. Borrowing heavily on the technology of its big brother, the ART amplifier, the Classic Sixty preserves the distinctive tonal character of individual instruments and voices, with each clearly located within the overall acoustical environment of the original recording. Musical transients are reproduced with realistic impact, but without artificial enhancement. Like its more costly siblings, the Classic Sixty captures the emotional impact of the live event, never getting between the listener and the musical performance. There really is no mystery to the basis for outstanding musical performance: best results come from simple circuits executed with quality parts. The Classic Sixty amplifier circuit design is about as simple as possible, employing just seven vacuum-tubes. Single-ended triode voltage gain and inverter stages are coupled to an output stage comprised of a single pair of ultra-linear operated EL34 tubes for each channel. As it is critically important that the DC voltage supplied to the gain stages be absolutely rock-solid stable, these voltages are provided by simple but highly effective discrete voltage regulators. And speaking of simple, maintenance of the Classic Sixty could hardly be easier: the owner need only make a simple bias adjustment using the built in bias indicators when installing fresh output tubes. The use of premium quality component parts is the other half of our underlying design mandate. In this area as well, the Classic Sixty is a leader in its class. Precision, metal-film resistors yield low noise performance for greatest clarity. Polypropylene and polystyrene capacitors, chosen to achieve a high degree of temporal accuracy, are specified for both the audio circuits and the regulated plate voltage supplies for the input and inverter stages. The result is an exceptional range of dynamics – reproducing both subtle variations in level as well as dramatic loud crescendos. Our proprietary trans-spectral wide-bandwidth output transformers contribute importantly to the extended, “airy” highs that help distinguish the Classic Sixty from ordinary tubed amplifiers. The Classic Sixty offers an ideal introduction to the joys of modern tube amplifiers, while the ease of use, low maintenance costs, and reliability will be a revelation for those who have only experienced “entry-level” tube gear. Those who wish to take the experience a step further will want to investigate the upgraded Classic Sixty SE, which upgrades the output tubes to KT120s and incorporates CJD Teflon Capacitors and ultra high-performance metal foil resistors in strategic applications in the circuit. Either model is sure to rekindle your passion for enjoying great music in your home.

The LP125sa Stereo Amplifier and LP260m mono-block are the latest in the highly regarded series of conrad-johnson vacuum-tube power amplifiers. The LP125sa offers a compelling combination of the audio excellence one expects from conrad-johnson, the convenience of a single stereo chassis, and, at 125 watts per channel, sufficient power for the majority of high-end speaker systems. Those with more demanding speaker systems will want to turn to the LP260m mono-block powerhouse, rated at 270 watts. Both amplifiers are capable of capturing the delicate textures and subtle nuances of live music while maintaining control with the authority that comes with ample power. Nearly identical in both models, the audio circuit consists of three stages. The input signal is amplified by a single-ended triode amplifier designed for wide band width. The signal is then direct coupled to a cathode coupled phase-inverter. This high cur rent, triode phase-inverter stage provides a bal anced, low impedance drive to the output stage. Output power is developed by KT120 power tubes (two pairs per channel in the LP125sa, four pairs in the LP260m), chosen for their excellent sonic character, high power capability, and reliability. The output tubes are operated in ultralinear configuration which offers a desir able combination of high power and low distortion. Massive output transformers with intricately interleaved wind ings afford extended bandpass and high phase linearity. A small amount (about 12 dB) of loop negative feedback reduces distortion and achieves a sufficiently high damping factor to control reactive loudspeaker systems. Power supply design is every bit as critical to the performance of an audio component as the audio circuit itself. Separate, low impedance, discrete dc power supply regulators are provided for the input and phase-inverter stages, preventing the output stage from modulating these stages through the power supply. These amplifiers require no complicated adjustments or specialized equipment to main tain. To assure continued peak performance, the owner need only make a simple bias adjustment when new tubes are installed. Built in LED bias indicators allow the user to make this adjustment using only the supplied bias adjustment tool.

ART Amplifier The limited edition ART Amplifier is designed to be a reference amplifier for the use of industry professionals as well as dedicated audiophiles. Like its companion GAT Preamplifier, the ART Amplifier will be offered in an edition of just 250 units (125 pairs) to be sold through selected conrad-johnson dealers and distributors. Those who do not need the prodigious 275 watt power delivered by the mighty ART mono-blocks will want to consider the ARTsa Stereo Amplifier. Nearly identical cosmetically (one more tube in the front), it is exactly an ART amplifier divided into two channels, each producing a solid 140 watts. At conrad-johnson, our approach to circuit design is predicated on the principle that the surest path to both state-of-the-art musicality and exceptional reliability is simple circuits constructed of the finest available parts. These ART amplifiers exemplify this basic principle. The audio circuit has just three elements, each as simple as possible, and each essential to the operation of the amplifier. A voltage gain amplifier (a single triode) is direct-coupled to a cathode coupled phase inverter (each phase handled by a single triode), which in turn drives the output stage. For the ART mono-blocks, four pairs of KT120 output tubes, chosen for their musical accuracy, high power, and reliability, endow this amplifier with a muscular 275 watt output rating. For the ARTsa, two pairs of KT120 output tubes in each channel produce 140 watts of power per channel. A small amount (about 12 dB) of loop negative feedback reduces distortion and achieves a sufficiently high damping factor to control the reactive load typically presented by high-performance loudspeaker systems. To assure continued peak performance, the owner need only make a simple bias adjustment when new tubes are installed. Built in LED bias indicators allow the user to make this adjustment using only the supplied screwdriver. Separate, low impedance, discrete dc power supply regulators are provided for the input and phase-inverter stages, thoroughly isolating these stages from the power demands of the output stage. These power supplies are designed to maintain a rock solid supply at all audio frequencies. Component parts contribute importantly to the sonic performance of any circuit design. The ART amplifiers maintain the exacting quality standards for which conrad-johnson is internationally known. Resistors are precision laser-trimmed metal foil types. Coupling capacitors are the new Teflon CJD caps, while the power supplies use large value polypropylene capacitors in parallel with CJD Teflons. There are no electrolytic capacitors in the audio circuits or in the related power supplies. Proprietary wide-bandwidth output transformers contribute to excellent high frequency performance. Even the machined gold plated OFC connectors and the internal wiring have been carefully selected for optimal sonic performance. Attention to every detail enable us to extract the full potential from our circuit designs and ensures that our products will perform to this potential for years to come. The ART and ARTsa amplifiers are built without compromise to achieve a new standard in musical performance, and they are built to last.
