then:
The final result will be TERRIBLY GOOD.
- Cyrus Audio CD t - a cd reading mechanism that, simply, reads more data, does not sound "digital", and make available a perfectly coherent and complete picture (in defiance of the ones that even now thinks that all the cd reading mechanism sound the same).
- Metrum Amethyst - The wonderful new DAC without any digital contaminant, with resolution, natural sound.
- Euphya Alliance 280 - an integrated amplifier with an amazing and unbelievable musical talent!
- Spendor Classic SP3/1 - The precision of tone of a true 'english school' speaker; fascination and expressivity.

Please note: some changes can be done to suit the system to your specific needs and installation. Please check the speakers dimensions and the installation point. Please contact us for any other information and regarding the integration of the system in your room.
The Radian is the standard unit of angular measure. To call our systems we adopted some conventional names of the unit of measurement because they are universal and simple to remember. In physics, a unit of measurement is a definite magnitude of a quantity, adopted by convention and used as a standard for measurement of the same quantity. We think that our systems, thanks to the care which they were built and for the performance they allow, can be considered a standard in their class.

AN AUDIOPHILE CD TRANSPORT WIDELY SEEN AS THE BEST CD TRANSPORT IN ITS CLASS.
It uses many of the top end components put into our flagship CD Xt Signature. With our Servo Evolution disc reading engine, the CD t houses many advanced components which make the sound it produces absolutely stunning. Which is why this product is widely regarded as the best CD transport in its class, even outperforming its more expensive competitors.
The reason the CD t can deliver such unusual value is Cyrus’s multi-award winning CD technology Servo Evolution (SE2) which is able to read more data ‘right first time’ from a CD than any other CD system.
A multi-regulated power supply allows the Servo Evolution software to work with miniscule precision, pulling huge amounts of data from your disc and transporting that to a separate DAC without adding or taking away anything from the music itself.
This allows the Servo Evolution software (which has been updated specifically for this product) to work with high precision, pulling huge amounts of data from your disc without adding or taking away anything from the music itself.
Among many component upgrades, an advanced loader has been chosen for this audiophile CD player, with LED disc detection technology for better detection and loading control.
Servo Evolution
Our SE platform is specifically engineered to retrieve data from an audio CD with the fewest errors. To provide ideal data output for hi-fi, Cyrus controls the whole electromechanical servo system providing superior quality audio than previously possible with conventional drives.
Pure Transport Operation
By removing the onboard DAC, the CD t works purely as a digital transport. Removing additional circuitry allows the CD t to focus purely on data retrieval and a high performance digital output.
Connectivity
The CD t benefits from optical and coaxial outputs which provide connectivity to a variety of DAC’s. CD t can be connected to other Cyrus units via our unique MC-BUS connections.
Precision Loading Drive
CD t features the latest generation of our slot load CD technology. This quiet and low contact mechanism provides myriad benefits to the traditional tray method of loading a CD whilst also de-cluttering the front panel for an improved aesthetic.
"An exceptionally talented transport for the asking price, the CD T delivers a performance that’s difficult to criticize".
"There's a level of transparency, clarity and insight that you’d be hard-pressed to find elsewhere at this price".

Servo Evolution CD Transport at a glance
Servo Evolution – the first audiophile standard CD platform. Whereas almost every other CD player uses a standard off-the-shelf disc reading platform with the focus on the DAC section, Cyrus took the unique move of creating something better: our own disc reading technology.
The benefit of the Cyrus Servo Evolution technology is the ability to pick up more data from the disc first time round rather than relying on error correction to fill in missing gaps in the data.
This supplies the DAC with up to 20% more information than the conventional design and explains the higher resolution that all Cyrus CD players are capable of producing.
All of our CD players now use our third generation servo firmware which provides audible improvements to the reading of CDs.
Benefits of Servo Evolution include:
• Pulls more data from the disc than typical disc-reading systems
• Up to 5 times fewer data errors
• Reads more data ‘right first time’ than any other CD system
• Less dependent upon error correction
• Lower noise interference
• Improved optic control accuracy
A standard CD-ROM drive is optimised for high speed data retrieval. It is not the best tool for reading a CD audio disc in high definition. Other proprietary drives are typically low cost, high volume designs with inevitable compromises in the early stages of the data retrieval process. In order to achieve the perfect sound replication that we strive for, it is simply not enough to take the data from the CD, feed it to a DAC and expect the best possible audio performance. It is commonly misunderstood that CD data retrieval is digital and therefore always perfect. The laser light reflected from the CD surface is converted into an electrical signal, which is in fact an analogue signal. The quality of this analogue signal is directly linked to the number of errors in the later digitising process. A good analogue light signal is completely dependent upon the ability of the servo systems to control the focus of the laser light spot, providing smooth tracking of the data stamped onto the disc. The Cyrus-designed system, unlike the off-the-shelf servo systems used by almost every other manufacturer, is optimised for audio data retrieval – and the proof is in the sound.
When evaluating our CD players please ensure that you use original CD’s to evaluate the performance and not copies of the originals (CD-R’s) as the burning engines in most CD burners devalue the benefits gained by our SE engineering. Not all CD burners do a good job of creating copies from the original disc and it’s a shame to compromise the fine engineering that makes our players sound so valuable, by feeding them with compromised information from the very start.
Cyrus developed the Servo Evolution hardware and firmware to attempt to resolve the problem of lost data as the disc is read. We refer to this suite of engineering as a CD ‘engine’ as it covers a collection of hardware and software engineering often rather too complex to interest a casual reader.
The problem:
Hi-Fi manufacturers generally do not have the deep specialist servo firmware experience or investment budget to use anything other than off-the-shelf (OEM) CD drive ‘kits’ developed for mass production (CD loader, laser, sled mechanism and firmware to drive this set of parts). The engineering to make the mechanical parts work reliably in the intended environment is complex and sophisticated and therefore expensive to develop. Economics mean OEM kits are developed for the largest customers such as automotive markets. Because disc drives contain small, complex and mass produced parts, they require sophisticated firmware to keep the mechanical parts positioned over the data spiral on the CD. Even more problematic is that the big customers need this to happen while, for instance, a car is bumping 1.5g vertical acceleration over a pothole!
The answer is to optimise the servo code for a tough environment and buffer the output into a powerful averaging system or error corrector to provide an unbroken data stream as the car bumps along. The resulting output will play but contain a high ‘bit error rates’ that need the errors, or gaps in data, filling in with an approximation of the data/music. Clearly this is a work around solution for a harsh car environment but not ideal for the sound quality standards of a high resolution HiFi system in your living room. However commercially it does work for many mass market applications where the subtle leading edge information that would raise the hair on the back of your neck at home, is unlikely to be missed at 50 MPH with 80db ambient background noise in a car. So this is fine for mass market applications but is a severely compromised source in the mind of a Cyrus hi-fi engineer.
By comparison, hi-fi is a tiny market by volume and it is therefore not attractive for large drive manufacturers to offer a special system. Cyrus desired a disc drive that could read data ‘right first time’ without repairing gaps with approximations through error correction algorithms.
The solution:
Because the needs of an in-car CD kit are very different from the needs of a domestic hi-fi, Cyrus had to decide if CD had a long enough life to make the substantial investment worthwhile. The decision was made and over 12 months three engineers worked to finish our unique SE (Servo Evolution) platform. The result was the world’s highest resolution CD engine. Our CD engine is very different from OEM kits as it runs the disc at 1x speed (not 50x for a PC drive) meaning we can optimise the controller motors to work much more accurately rather than just fast. We require accuracy rather than speed and this is where our SE system is so different to CD kits. So how good is the latest SE firmware and hardware? By comparison, Cyrus’ bit error rate delivers an output with 20% fewer errors than the next best system. In CD data terms, this is an enormous increase in resolution. Just take a moment to consider how much effort goes into gaining 5% improvement in amplifier noise or distortion. A 20% improvement in error rate means the error correction works infrequently, motors are rarely now asked to drag the laser sled back to re-read data, and focusing accuracy is maintained more of the time. The result of all this engineering is a data feed capable of greater subtlety and resolution because it gets more data from the disc ‘right first time’.
Traditionally, hi-fi designers have attempted to improve performance by focusing on post-servo options because their data quality is fixed by the needs of the mass market. Cyrus was motivated to develop SE because we believed that getting the data with greater accuracy was the correct engineering route as opposed to attempting to fix errors retrospectively. Because we have fewer errors, data is retrieved ‘right first time’, and therefore we have far less need for error correction, so the whole system is calmer with much reduced motor noise in our ground and power planes. Clearly not needing error correction nearly as often means our sound is a closer facsimile of the data on the CD because it is less ‘corrected’ and the players DAC section is not affected by power supply noise from motors in adjacent ground planes. It is also important to differentiate between those manufacturers who market a “special” buffering or correction system. These are not high resolution servo systems; they are attempts to improve on the generally available mass-produced OEM offerings made for the mass market and these kits are limited by lower resolution servo output.

SPDIF or Digital Optical
As good as digital coax is there are still some inherent problems. Digital coax is still limited to the problems of an electrical signal. They are affected by the materials they travel through and the electrical fields that are surrounded by.
Ordinary Cables Can Be Susceptible to Performance-Degrading Jitter
If your digital coax cable’s dielectric isn’t perfect, it won’t precisely match the 75 Ohm impedance of your components and speakers. This means it won’t be immune to jitter, which can be substantial enough to produce audible imperfections like phase distortion, increased noise floor, decreased bandwidth and lack of clarity. The TRC-222 superior quality construction and advanced features help maintain 75 Ohm signal integrity, while ultra-wide bandwidth capabilities—in excess of 2GHz—help eliminate jitter to give you superior speed, accuracy and sound.
Get the Best Sound Your High-End Components Have to Offer
Today’s cutting-edge, high-end digital audio source components deliver multi-channel sound that’s truer and more detailed than ever before. So don’t limit their performance with ordinary cable—get the superior sound your expensive components and digital coax connections are capable of.
Digital coaxial cables.
Digital coax transmits signals electrically. The electrical signal pulses through the copper wire at the heart of the coaxial cable. It's shielded from interference by an double wound cross braided wrap.
One of the first things you'll notice about digital coaxial cable versus traditional audio cable is the cost. Because you're dealing with a thicker, shielded cable, digital coax costs quite a bit more than what you're used to paying for a standard RCA cable.
Because of the cost, you might be tempted to use a standard analog RCA audio cable to make a digital connection. Not a good idea. A traditional RCA cable isn't shielded, nor does it have the bandwidth that coaxial cable provides. A digital coaxial cable offers 75-ohm impedance and a wider frequency bandwidth than the thinner, unshielded RCA cable. If you do connect a standard RCA audio cable, you'll find that you start to lose the signal over long distances, due to the lack of shielding. That lack of signal typically manifests itself in the form of stuttering audio—you're not getting all the digital bits on a consistent basis. You may also notice interference from other electrical devices, including electric lights. The longer the cable run, the worse the signal loss; you may not notice it with short cables (three foot or so).
NOTE
A single digital coaxial cable carries all available audio channels. You only need a single cable to carry right and left stereo signals, or the 5.1-channel surround sound signals. Completely redesigned, the new Ultimate Digital Coax Cable offers even better performance for high-end Digital Coax applications. This cable has more than enough performance to be at home on reference Home Theater Systems, yet is priced to be affordable. World-class performance at an incredible price? Yep, that is the Beresford Cable recipe for building the Ultimate audio and video cables.
The Amethyst is our new entry model using our praised "forward correction technology" . Due to this technology a real 24 bits performance is realized and probably the most advanced way to give R2R technolgy new dimensions.
As a result music will be more exiting as details on very low levels will be audible. The Amethyst can meet the best systems today in terms of sound quality as it borrows all the good things from our top models Pavane and Adagio. Like her predecessor the Amethyst is designed for the same basic frame but electronics have been redesigned for future tasks. In addition we have implemented a new and powerful headphone amplifier having its own volume control.
The Amethyst is using two Transient R2R ladder Dac TWO modules. This simple design gave us lots of compliments and testimonials. Creating a high end dac has never been so simple. These modules can handle extreme high sampling rates but are limited to current industry standards which has its maximum (384kHz) on the USB input. The result of this process is an extremely fast and accurate behavior and brings listening experience on a much higher level.
High resolution linearity plot of DAC TWO (please see image "1000 step linearity plot DAC TWO module"). The analyzer is struggling to show us the last bits down to -140 dB. In case more bits are involved the steps are shrinking and more resolution is available. This extreme linearity is realized by our forward correction techniques and improves reproduction of the lowest musical details.
Despite the fact that both dac modules are build on the same board an extremely high channel separation of 110 dB is realized. This contributes to flawless positioning of instruments. However, we do not only evaluate a result basing on measurements, because sometimes they are taken at the wrong place. The perception of a sensible human brain/ear system is very important.
Still people do not realize the size of our dac modules (please see image of the DAC TWO on a credit card). For instance the Transient DAC TWO module has two R2R ladders, an FPGA and the I/V section under the hood. About half the size of a credit card and nothing to add except power and data. How simple can it be :-)
Just a note to discrete R2R ladders and why they cannot work properly (see
resolution table image):
1 no more accuracy than 0,01% so not more than 14 bits precision.
2 Too much temperature differences over the entire pcb leads to linearity problems.
3 Sensitive for pollution and humidity.
Therefore we only use lab grade laser trimmed ladder networks to get perfect
linearity and real 144 dB dynamic range. Next they should be encapsulated to
avoid mutually temperature changes and pollution. This table tells everything
but also tells you that more than 24 bits at the analog side is an Utopia due
to Johnson noise. Do not be fooled!!How important proper signal routing is in case of mixed disciplines both analog and digital on one pcb. Further proper star ground can avoid any hum. Look at the picture named "New Generation DAC TWO proto dac board": DAC TWO used on a new proto board. An 882 Hz test tone at -90 dB is used but no rests of 50/100Hz is visible.
The headphone amplifier has 1W of output and gets his power from a powerfull 30VA power supply. When the the Amethyst is used as a dac this power will be available for the dac only.

Black RCA Phono Interconnect (patent pending), pair, 1 meter lenght. ( different lenghts can always be requested contacting us).
Please note that these interconnects are directional and for the best sound the signal must travel in the direction of the arrow near the centre of the cable.
The grip in the phono plugs is adjustable enabling you to get the best possible fit.
Most amplifiers tend to be built using solid state technology and that normally requires a certain tuning and matching from an interconnect. So these are matched to low impedance devices such as nearly all solid state devices and most modern Valve amplifiers but having said that there are the odd few solid state amplifiers out there that would require a higher impedance match.
By matching the interconnect to your system in this way the ringing (a common fault) is virtually eliminated giving you a clearer, less distorted signal path than you would normally be able to achieve.
The Alliance 280 received several appreciation from the press. Quality components, skilfully assembled make an integrated amplifier that is a distilled of immediately perceptible musicality. A handcrafted product, distant from sirens of the marketing, beautifully made in France.
Advantages
- Best musicality and nuances
- Very natural listening
- Seriousness of the manufacturer
- Optional power supply
A French manufacturing amplifier which I consider very special particularly for its nature and its fluidity. The listening brings many nuances and keeps a permanent concern of sweetness. An optional power supply I recommend when certain speaker systems do require a supplement of energy. A very charming integrated amplifier.
Solid state integrated amplifier with 40W/channel. The reproduction of the Euphya Alliance 280 integrated amplifier respects the artistic intention of the musician, as good as the natural timbre, the rythm and the natural holography of the original creative execution. Wonderful fullness and fluidity.
This multi-talented integrated amplifier allows a tonal balance of rare coherence on all parameters to release the deployment of the sensual pleasure of the music and the natural exciting felt at live acoustic concerts. So, it's easy to deepen the musical structure of the reproduced programme. Dedicated to all the good listeners, also when it indulges in the aesthetic standards generally appreciated by audiophiles, it is so generous to set music free.

Tellurium Q Black II Speaker Cable, Beryllium-Copper factory (UK) terminated version.
Tellurium Q Black was our first cable and we knew we were on to something special when we took the prototypes to various dealers for their comments and input. One in particular would not believe that it could match the somewhat thicker more expensive cable in his demonstration system.
We sat down and listened to some of his familiar music tracks, then we swapped the cable for Tellurium Q Black. He sat forward, looked at us and quite seriously asked what else we had done to his system while we were changing the cables over. It was only when he swapped the cables himself a couple of times he believed the evidence of his ears.
So why Black II? Despite Black winning multiple awards, surprising owners with it’s performance and more people than ever choosing to use it in their systems?
We have been learning and developing, especially in the last few years and have come up with a way to make this little gem even better. The only thing to do was to give it to our customers. Switch Black for Black II and it is completely obvious which is which. Once you hear the difference, it is also completely obvious why we felt compelled to upgrade Black in the way that we have.
We think you will get more from your music and hope that you love Black II as much as we do.
Black Family: Smooth, fine detailed and great resolution while actually reducing apparent harshness. Music is presented as a coherent, organic whole, with a jaw-dropping sense of realism and naturalness.

Spendor Classic series
The Spendor Classic Series is a range of stand-mounted loudspeakers which has been developed from the experience of over 30 years of Spendor heritage and experience.
Whilst there have been constant advances and refinements to the original technology used in the first Spendor products, the attention to fine detail remains and is embodied in the award winning Classic Series products.
The Latest 'R' series classic speakers combine all the advantages in materials technology that have been developed for the new Spendor speakers, but retain the traditional styling and sound balance one would expect from these monitor grade loudspeakers.
Spendor Audio at a glance
Spendor loudspeakers are designed and hand built at the Spendor factory in Hailsham, Sussex in the UK. Traditional craftmanship, skilled design capability and modern engineering materials all combine to produce superbly built loudspeakers with models to suit any taste or application.
Spendors unique bass and mid drive units are also designed and built in Hailsham. Many other manufacturers are content to buy in standard, or slightly modified versions of drive units easily obtainable from component suppliers, whilst claiming the drive units as their own. Not so with Spendor. The main drivers are the heart of the loudspeaker, and should be designed and built with care, and without compromise.
Originally founded in the 1960's by Spencer and Dorothy Hughes, Spendor grew out of the expertise gained in the BBC's sound engineering department. The original BC1 design became the studio monitor of choice and soon this and other designs were to be developed for the consumer market.
For well over 30 years a succession of distinctive and innovative products has set a reference standard for consumer and professional users. Many Spendor designs have earned international cult status amongst discerning audiophiles and sound engineers, and the virtues of such classics as the Spendor BC1 and LS3/5a are embodied in today's products.
