Heed Audio CanAmp Headphone Amplifier Many audiophiles use headphones to enjoy their system. While some people are compelled to do so by their living circumstances, others simply prefer cans to loudspeakers. However, some amplifiers either have no headphone output, just as they don't have phone stages, or if they do have one, it is often just a simple IC-based stage. Regrettably, even many outboard amplifiers resort to this simple - and cheap - solution, making it impossible for headphones to perform at their best. Let us introduce the CanAmp, offering a no-compromise solution at a realistic price - in fact, given its technology and manufacturing quality we might even say at a "discount" price.Headphones can be considered as high quality loudspeakers, but with a much lower power requirement. For this reason, they have distortion levels an order of magnitude lower than conventional speakers, and therefore are capable of showing up amplifier deficiencies more clearly. What's more, headphones are one-way systems, with very few exceptions, and for this reason crossovers do not interfere with sound quality. Consequently, a headphone amplifier must offer the best possible sound quality, even at very low volume levels, whilst working not unlike a real power amplifier. The CanAmp is a two-stage amplifier. While the first - voltage gain - stage is based on an integrated circuit of the highest audio pedigree, the second - power gain - stage is a single-ended, pure Class-A amplifier. It enables the CanAmp to drive virtually any headphones from 32 ohms up to 600 ohms. The unit has no internal wiring, and the signal path is kept to a minimum on its PCB. Its high-quality, 1 dB-tolerance Blue Alps volume pot goes through a further selection process during manufacturing to achieve an even tighter, 0.5 dB tolerance. The CanAmp not only has a line-level input but offers a line-level output to boot; it can therefore be connected to the TAPE MONITOR output of an amplifier, leaving the TAPE output free for additional components (MP3, MiniDisc, CDR, etc.). Gold-plated RCA terminals are used, and soldered directly onto the fibreglass PCB.Technical specifications Input sensitivity/impedance: 200 mV/10 kOhm Power output: 300 mW (100 Ohm) Signal-to-noise ratio (unweighted): 85 dB Distortion (THD, 1 kHz, 100mW): <0,05% Frequency range: 10 Hz-50 kHz (±0,5 dB)

Audio QUESTARMM and MC Phono StagesThe QUESTARs are destined to be the MVPs (Most
Valuable Phonostage) of the Heed analogue range. At first glance, they
physically resemble the Pulsar, our previousentry-level MM phono stage, but
looks can be deceiving. Under the hood of their hefty, shielded steel chassis
beats the heart of our award-winning audiophile Quasar MM/MC phonostage,
conveniently divided into neatly-specialized a' la carte portions.The QUESTAR MM
incorporates the Quasar’s unsurpassed MM circuitry. Its sibling, the QUESTAR MC
deploys a streamlined version of the Quasar’s MC stage, eliminating the need for
jumper switches by optimising the amplifier to suit the 300-600 µV output range
characterising the vast majority of today’s moving coils. Considering its
generous 18 dB headroom, ideal cartridge matching is virtually assured.The
internal construction of the QUESTARs meets the most critical high-end standards
in every respect. The amplifier employs an entirely dual-mono configuration and
uses a two-stage - passive/active - RIAA equalisation. Gain adjustment has been
optimised for maximum headroom and highest signal-to-noise ratio. Component
parts are selected to exacting tolerances matching those of our flagship
Quasar.The QUESTARs are suitable for any line-level amplifier input, and can
easily drive virtually any length of interconnect. There is no internal wiring
or binding, and all high-current parts of the circuit are shielded. Both models
feature gold-plated RCA terminals soldered directly onto the PCB, limiting all
signal paths to a bare minimum.The QUESTARs utilise an external “wall-wart”
power supply to avoid undesirable electro-magnetic interference within the
chassis, distinguishing them from their predecessor, the all-in-one-box Pulsar.
Sonic performance can be even further enhanced by upgrading to the Quasar’s
substantial separate box PSU, constructed around a massive 60 VA toroidal
transformer with low-density magnetic field and minimal dispersion. With
substantial 40,000 µF capacitor filtering, the Quasar PSU can feed the QUESTAR’S
circuitry with the kind of super-clean current usually delivered only by
battery-based supplies, even with extreme dynamic swings.Technical

Heed Audio QUASAR State-of-the-Art MM / MC Phono Stage The signal processing of cartridges is one of the most delicate jobs in amplification. All the more so because it isn't done merely by boosting a few hundred microvolts to a few hundred millivolts. In fact, at this thousandfold amplification (60 dB) the signal must be processed as cleanly and noise-free as possible. The extremely low signal level and the frequency-related amplification which arises from the RIAA equalisation curve applied in the cutting of LPs make the highest demands of the circuit topology and technical realisation of a phono preamplifier.The QUASAR, with its discrete conception and wide range of features, represents a unique bargain at this price level. The QUASAR is built in dual-mono configuration from the power supply upwards. There are two separate amplifier stages for MM and MC cartridges, both being fed from their own regulated power supply arrangement. Optimum adjustments to the cartridge in use can be applied for sensitivity and load by various settings of the jumpers on the PCB. The two separate outputs with different sensitivities make it possible for preamps or recorders to be fed via 'Low Out', whilst its 'High Out' can drive power amps directly.The output stage has huge headroom at extremely low noise levels and, due to its low output impedance and high current delivery, can drive long interconnect cables without any sonic degradation.The enhanced power supply of the QUASAR is based around a 60 VA toroidal transformer with low-density magnetic field and very little dispersion. This power, together with 40,000 µF filtering, can feed the circuit with the kind of super-clean current usually delivered only by battery-based supplies, even with extreme dynamic swings. The entirely discrete conception, as well as the short signal paths of the QUASAR, combine the best audiophile tradition with innovative circuit design. This new phono preamplifier makes analogue high-end reproduction affordable at last! Technical specifications MM input: 3 mV /47 kOhm / 100 pF MC input: adjustable Sensitivity: 100 µV - 220 µV - 600 µV Impedance: 100 Ohm / 220 Ohm / 470 Ohm Output voltage: "Low Out": 220 mV/100 Ohm "High Out": 775 mV (0 dBm)/ 22 Ohm The QUASAR was awarded first prize for Best Phonostage in 2002 at the biannual "Image Hifi Awards" in Germany, one of Europe's premier hi-fi accolades.

The thesis φ (phi) is a no-compromise phono preamplifier for all vinyl connoisseurs using a top-class turntable. Just like the α preamp, it is also fed by the thesis π twin PSU. By using two independent – MM (moving magnet) and MC (moving coil) – amplifier circuits, it is possible to use two record players connectedsimultaneously. Cartridge matching is highly customisable for gain and impedance on the rear panel of the unit by jumpers. Noise characteristics, dynamic range, headroom and frequency response of the thesis φ are second to none.
Alimentatore per giradischi a 2 velocità 33/45 giri 220V ( plug "N" play)
The speed accuracy and stability of many belt drive turntables driven by a synchronous motor depends entirely upon the quality/consistency of frequency delivered by the domestic mains supply. However, mains frequency at 50Hz / 60Hz leaves much to be desired since it is subject to fluctuation, distortion, and other innumerable problems prior to reaching your listening room. The Heed ORBIT 1 and Heed ORBIT 2 off-board turntable power supplies offer a sophisticated solution to stabilise and improve any 4-pole, 110V synchronous motor drive, elevating your deck's sonic performance to startling new levels of musicality. Backgrounds become „blacker", separation of instruments more sharply defined, while bass gains added depth, and the overall soundstage widens accordingly.Both ORBIT models give the added convenience of electronic speed change between 33 1/3 and 45 RPM via one single, elegant push-button in lieu of the rather fussy manual speed change arrangement of many turntables (removing the platter and shifting the belt on the motor pulley time and time again.)

versione DACTILUS 3+Q-PSU Convertitore Digitale Analogico con Alimentazione Q-PSU 890,00 euro
In designing the Heed DACTILUS, our aim was to create a D-to-A device which makes any digital source – CD players, DAB tuners, etc. – more enjoyable to listen to in musical terms. Used with higher ranking digital components it still holds its own against many on-board DACs with its strikingly different approach – a less analytical and processed presentation of music which conveys the musical message in a very fluid, natural, rhythmically engaging fashion. Even the primal Dactilus 1 with our first-ever DAC circuitry, the Dactil 1.0 module was capable of doing all that: "...it's seldom anything other than an enjoyable one to listen to and we're happy to recommend it..." as leading UK Magazine Hi-Fi Choice found it in their 2009 review. The all-new second generation Dactilus 3, equipped with our new Dactil 1.2 DAC module, is capable of 24bit/192 kHz high resolution signal processing while extending upon the virtues of the earlier model, injecting extra transparency, information retrieval and dynamic capability. The features list is modest: optical (Toslink) and electrical (Coax SPDIF) digital inputs (selected using a rear-mounted switch) or an asynchronous, 24bit/192 kHz capable USB input into a single unbalanced output.

The Obelisk DA is our multiple input, remote-controllable flagship Digital-to-Analogue converter. At the DA's heart lies the new the Dactil 1.2 DAC card, based on a Wolfson D/A chip and a new Cirrus receiver, and capable of 24bit/192 kHz high resolution signal processing. A deceptively simple module with excellent musical qualities, the Dactil 1.2 manages to scale new heights in the employ of the Obelisk DA's 'no compromise' approach, featuring entirely independent supply rails for its analogue and digital sections. The Obelisk DA accommodates 5 digital inputs: two S/PDIF (one RCA, one BNC), two TOSLINK and one USB. Two outputs are available, one with 1.25V output voltage as direct connection from the converter, while the other one is boosted to 2.5V by a dedicated preamp section similar to the analogue circuit of the PRE, making it an ideal source for fans of passive pre-amps. The DA is not only the ideal compliment to our DT compact disc transport, it will also extract the very best from any digital source: computers, media servers, DAB tuners, satellite boxes, etc. And its modular DAC card and USB interface upgradeability assure future-proof enjoyment for many years to come.

Unleashed by ION Systems in what only now seems like the twinkling of an eye during the early 1990s, Richard Hay’s original amplifier concept stirred emotions in Hi-Fi freaks and music lovers alike. The Obelisk was something unabashedly different. As Alec Issigonis set the automotive world on its head with his Mini in 1959 – a groundbreaking design with front wheel drive, transverse engine, sump gearbox, and phenomenal space efficiency –, so the half-width, shoebox-sized Obelisk challenged the status quo with its decidedly austere exterior, flexible upgrade possibilities, and controversial non-DC-coupled topology (by then, largely considered virtual heresy for any serious transistor-based amplifier). But above all, it managed to render recorded music, well, disarmingly musical.Like the metamorphosis of the classic Mini into the ’new MINI’ under the BMW banner with modern safety, emissions and manufacturing principles, so too we have resurrected the Obelisk – by applying advanced design solutions, utilizing superior-quality component parts, and meeting higher production standards.Therefore, we take tremendous pride in presenting the Heed Audio Obelisk Si integrated amplifier, its supplementary Obelisk X-2 outboard power supply, and matching Obelisk PAS stereo power amplifier.This very first 21st century Obelisk sports 5 line inputs, remote volume control, a beefed-up power supply, stand-by facility, and the ability to accept either optional phono stage or DAC modules. And that’s not to mention an entirely re-imagined preamplifier section based upon, and yet newly refined from our innovative 2-box Luna preamp. But we have never lost sight of the pivotal principles set forth by its classic predecessor; the active involvement of Richard Hay throughout the entire development of the new Obelisk range has been indispensable.Technically speaking, the Obelisk defies conventional measurement. Mere specifications can be wildly misleading here. Consider output power: the Si is conservatively rated at 35 watts per channel into 8 ohms. While this represents a humble enough watt/cost ratio, here 35 watts don’t exactly equal 35 watts, since the Obelisk’s non-DC-coupled design behaves rather more akin to valve amplifiers (roughly speaking, Richard Hay’s approach was sort of a “valve amp built with transistors”) of similar rating. With this kind of power on board, better valve amps are capable of astonishing dynamic authority, and we’re more than satisfied that the Obelisk Si adheres to this paradigm and then some. The Obelisk X-2 power supply (in fact, a dual-mono power amp PSU) ups the ante to a full 50wpc (again, behaving more like so many valve-watts), while allowing the original on-board power supply to dedicate itself entirely to the preamp section. In other words, with the addition of this single device, the Obelisk Si evolves into a fully-fledged dual-mono pre/power combination! Finally, the ultimate Obelisk experience along the Si’s upgrade path is realized by the addition of the Obelisk PAS stereo power amplifier in bi-amp configuration with compatible loudspeakers.But perhaps the most distinguishing characteristic of the Obelisk Si, in any configuration, lies in its inherent and exceptional musicality. With each listen, we are keenly reminded of how organic and life-like recorded music can be. But don’t buy this story from us. Just read the verdict of one of the world’s most distinguished music & Hi-Fi publications, Diapason (France): „The Obelisk deftly negotiates dense passages with aplomb, yet is always accompanied by finesse and simplicity, indeed, consider the best tube amps. It is much closer to the "live" magic of a reference-quality 300B than it really has any right to. ...The Si’s dynamic range approximates the spontaneity we hear attending a live performance, evoking the very same impression. A genuine revelation at a price, after all, without competition.” (And just two short months after this review was published, the Obelisk Si was named recipient of the coveted Diapason D’Or Award for 2008.)For even a fleeting experience with the real world is better than thousand words in hi-fi, do try and meet the Obelisk wherever you can – trade shows, Heed Audio dealers, happy Obelisk owners.

In other words, with the addition of this single device, the Obelisk Si evolves into a fully-fledged dual-mono pre/power combination. It is a substantial technical upgrade, and consequently a leap forward in sonic performance: it catapults the single-box integrated Obelisk into a much higher league.
Preamplificatore Stereo di linea con volume telecomandato; finitura Nero o Bianco
The Obelisk PRE is the "command center" of the
Obelisk range, a thoroughbred analogue preamplifier with the option of using one
or two of its inputs for digital-to-analogue conversion by add-on DAC modules.
It is a keenly priced design that we're convinced more than holds its own
against many class-leading but prohibitively expensive high-end competitors.
Although rather traditional in its basic topology, the circuit design of the
Obelisk PRE represents the convergence of cutting edge ideas with highest-grade
components. As opposed to many preamplifiers that have "dumbed-down" internal
power supplies in order to present more dramatic sonic benefits with optional
auxiliary power supply upgrades, the PRE has a sophisticated and generously
sized on-board power supply that is based on a top-quality Noratel transformer
and two 10.000µF Mundorf capacitors, custom made to our own specifications.
Nevertheless, the last ounce of the PRE's performance can be elicited by adding
the Obelisk PX power supply. The PRE accommodates 6 inputs of which one is
exclusively dedicated to the digital domain and can be used with our optional
Dactil 1.2 DAC module via 75 Ohm S/PDIF or TOSLINK connections, while a second
one will accept either a further DAC module (only via S/PDIF in this case), or
our optional MM phono module for vinyl replay (sans module, this input works as
standard line-level connection). Since DAC circuits are highly prone to
interferences caused by analogue circuits integrated nearby on the PCB, we
provided the on-board supply environment of the DAC module with two independent
supply rails using a smart „unit within the unit" solution. Furthermore, all
analogue amplifying stages (including the MM phono module) are built in
dual-mono configuration and fed through no less than seven fully regulated
voltage supply rails. Modules can be easily inserted into slots on the main PCB
and dedicated by jumper settings. Using modules internally instead of
stand-alone auxiliary units provides many advantages: absolute synergy, no
external cables and plugs, shortest possible signal paths, saving unnecessary
costs for external case and power supply, etc. The two pre-out connections of
the Obelisk PRE make various configurations possible. Beside traditional single
power amplification, it is also possible to use two power amplifiers for
bi-amping or active mode. A tape-out connection is also available for use with a
recorder or a headphone amplifier, ideally our Heed Audio CanAmp.

The enhanced power supply of the QUASAR, the Q-PSU that also can be used as power supply upgrade with other components like the QUESTAR phono stage or the DACTILUS D-to-A converter is based around a 60 VA toroidal transformer with low-density magnetic field and very little dispersion. This power, together with 40,000 µF filtering, can feed the circuit with the kind of super-clean current usually delivered only by battery-based supplies, even with extreme dynamic swings.
Alimentazione Dual per α (Alpha) e ϕ (Phi) simultaneamente con 2 uscite indipendenti
The thesis π (pi) twin power supply can feed the α and φ preamplifiers simultaneously. It has two independent sections, each with dual regulated power supply rails. In order to ensure an absolutely clean and stable power delivery, the thesis π uses high-grade components custom made by Airlink and Mundorf to our specifications, all massively overspecified for smooth and effortless performance even when pushed to its limits
One of the most difficult tasks we have
undertaken has been to extend the capabilities of the Obelisk PRE, which was
designed to perform beautifully as a self-contained unit. However, the Obelisk
PX dedicated outboard power supply manages to surpass even our highest
expectations. The PX is based on a sophisticated fully-regulated,
double-filtered circuit topology, which eliminates interference caused by the
mains supply, providing the cleanest possible current to the PRE. It features
very high grade components such as a Noratel mains transformer and four 10.000µF
Mundorf capacitors custom made to Heed's own specifications. This results in
extremely low noise, low inner impedance and negligible distortion performance.
Although the PX is primarily designed to partner with the Obelisk PRE, it can
also be paired to enhance the performance of our Quasar phono stage, Dactilus
DAC, Luna II preamp, etc.

Amplificatore con potenza stereo da 50W per canale; finitura Nero o Bianco
The Obelisk PS is a versatile stereo power amplifier, rated at 50 watts per channel into 8 Ohms, yet performing like a much higher rated amplifier due to its unique circuit topology and outstanding power supply section. It is entirely suitable for bi-amping, tri-amping or multi-room use. It is a perfect match for the Obelisk PRE. But above all, the PS is every bit an Obelisk. Our long-standing tradition of eschewing DC-coupling for a less "processed" sound with more natural decay of tones and uncanny realism has reached new heights with the evolution of the Obelisk PS. With the capacitor-coupled power amp stage of the Obelisk Si integrated (even more effective when quasi-pre/power configured with the addition of the X-2 PSU), we created a distinctively different sound signature much closer to the best of valve amplification than to conventional solid state presentation, as noted by many prominent hi-fi journalists — „It is much closer to the 'live' magic of a reference-quality 300B than it really has any right to." (Thierry Soveaux, Diapason), .... „It really does make that solid-state valve-sound a little closer to reality." (Jason Kennedy, Hi-Fi Choice) .... „with its liveliness and ease it's geared toward the intrinsic virtues of good valve amplifiers." (Markus Sauer, Hi-Fi Statement) . The PS proves that it is possible to push the envelope of the Obelisk topology. In doing so, we followed a simple path: we kept the proven dual-mono power amp circuit of the Si, improved its PCB layout, optimized all signal paths, opted for higher grade components sourced from the likes of Mundorf, Clarity Caps and Noratel, and upgraded the entire power supply. The result speaks for itself.

have easily been named the Obelisk Statement. What is the ultimate Obelisk power
amp like? How much can be extracted from capacitor-coupled power amp topology if
done uncompromisingly, no holds barred? Don't be fooled by the PM's deceptively
modest power specification — 70W into 8 ohm, 120W into 4 ohm — as it hardly says
anything about the real capability of this unit — a stable 200W delivery down to
1 ohm! And bearing in mind the unique Obelisk topology, those watts effectively
behave more like valve-watts. We're satisfied that the Obelisk PM can drive
virtually anything; even the most awkward loads can be handled with relative
ease. Drawing on an enormous power supply featuring custom-made components from
Airlink in the UK and Mundorf in Germany, employing shorter signal paths than
we've ever used in power amplification — signals are almost fed from component
leg to leg — all these small engineering details contribute to astonishing
performance results. Sheer power and technical ingenuity are one thing (well,
two...), musical performance is another, and one ideal which we hold above all
others is summarized in our credo — 'Forget Hi Fi — Remember Music'. The Obelisk
PM is indeed that rare thing: a most unforgettable musical brute. It is simply
the best power amplifier we've ever built. Specifications: Frequency

Amplificatore Mono a stato solido
The thesis ω (omega) monobloc power amplifier is an AC-coupled device in true Heed fashion that drives loudspeakers in a similar way to valve power amplifiers, but without their inherent problems related to the vacuum tube. Despite certain topological similarities to its valve counterparts, the thesis ω is best described as a quintessentially solid-state power amp that successfully gets around the often sterile, lifeless sound of most solid-state devices. We believe that connecting amplifiers to speakers by AC- instead of the prevalent DC-coupling results in amuch more natural, less “cropped” decay of tones. Freed from the cost containments of the Obelisk power amplifiers, we could achieve a no-compromise implementation of this topology in the thesis ω. With its very generously sized power supply, unlike valve amplifiers, it is also extremely stable even into the most difficult loads – continuous power delivery up to 160W or capability of driving loads down to 1.6 Ohm speak for themselves. It is capable of driving all kind of speakers except those with very low efficiency

If Heed were a pure electronics manufacturer, our thesis would end here. We are, however, designersand manufacturers of all-encompassing audioequipment. Just like our Obelisk/Enigma concept,the thesis also consists of electronics and loudspeakers.These are bound together in a synergicentity in which the speakers play a pivotal role. So let us introduce you to our second “enigmaticchallenger”, the envoy of thesis.Following our non-directional speaker concept thatfirst jelled in the Enigma, we have turned over a newleaf and created the envoy, a bigger enigma– literally. It is a dual TMR (transmissionline-reflex) 2.5-way non-directional speaker that improves onthe Enigma in almost all respects. By using two 6.5 inch drivers in two separate quarter-wave TMR chambers, the envoy performs an exceptionallydeep, voluminous and dynamic bass response, while its state-of-the-art tweeter not only preserves the Enigma’s uniquely open and holographic midupper range but makes it even more detailed, transparent and tangible. A breathtakingly realistic reproduction of music in all its facets, spaciousness and immediacy that casts a spell over the listener

When we listen to live music, we are not the least bit concerned about where the musicians are located in the room and if we move about the room, we experience the music wherever we are. Shouldn't a loudspeaker release music into the room in the same way? Conventional speaker systems, however, cannot faithfully recreate music as we hear it in a live setting. No matter how large or expensive they are, whatever type of cabinet design, drive units, cone materials, toe-in, or crossover techniques are implemented, directional speakers will always YELL in your face, to a certain extent. At Heed Audio, we have found that loudspeakers with a non-directional radiation pattern are best able to simply let the music into the room. At the same time, other things begin to happen. Rather than feeling compelled to sit rigidly in the "sweet spot", it is possible to move to the right and left, forward or backward, up or down, and the music follows. As a further benefit of using suitable conventional drive units in an angle wide off-axis, there is no need to restrain high-frequency energy in order to tame the tweeter's on-axis response. High-pitched tones of percussion instruments like cymbals and hi-hats, but also horns or strings can be reproduced with life-like impact, vibrancy and dynamics without ever getting strident.The Heed Enigma delivers an almost uncanny sense of "being there" with the musicians and instruments. It seems to transform the domestic listening space into the concert hall, or jazz club, where the music is fully present wherever you might be sitting. Tonality is natural and balanced all around the room, with fewer of the peaks and dips that occur when a speaker has to aim its output directly at the listener."...over at the Atrium, the Spendor dealer room might be playing jazz but it sounds astonishingly vibrant and exciting. It might have snaffled my best-in-show gong if I hadn't stepped next door to hear (yet more jazz) in the Profundo room. Here, an all-Heed amplification setup fed Heed omnidirectional speakers for a soundstage that went tall and wide and was oh-so inviting. Glorious. Best room, no question." (T.H.E. Show Newport Beach 2012 ― John Darko DIGITAL AUDIO REVIEW) The radical approach of this unique loudspeaker, however, only begins with non-directionality...
