The CD-T MkII was designed to play compact discs with a stunning level of resolution, dynamics and musical naturalness. 

The overall sense of transparency and purity is simply breathtaking, offering a sense of relaxed intimacy with the recorded performance. The playback mechanism continues to be the unsurpassed Philips PRO-2 and still one of the best dedicated CD mechanisms available and providing world class performances in a perfect engineered design.

After more than 5 years' production time of the CD-T and its unbroken success we have decided to essentially rework it and equip it with some special features. We have kept the legendary Philips Pro drive (to our opinion one of the best sounding CD-drive ever built and reissued again), the dual digital tube buffer with 6H14 (operating in the MHz range) and of course the typical elegant and timeless "Ayon" chassis. Special attention was paid to the new clocking system, the modified power supply, the new dual ground system and the possibility to raise the bitrate of the CD to DSD 128 by means of our DSD-converter module (optional). The CD-clamp-system was also optimised further and all digital outputs were galvanically insulated from each other; additionally, the classical and the tube-buffered outputs on the rear-panel are designed switchable.

The CD-T Mk II was designed to play compact discs with a new stunning level of resolution, dynamics and musical naturalness. The overall sense of transparency and purity is simply breath-taking, offering a sense of relaxed intimacy with the recorded performance. The CD-T Mk II is perfectly engineered with a very high built quality.

The CD-T MkII is available in 2 versions: CD-T standard and CD-T Signature which has additional PCM-DSD conversion option

Signal Path
We believe that the simplest circuits work best together with the shortest signal path. That is why our pre-amplifiers to date have used single-ended pure class-A circuitry. The shorter the signal path is, the less possibility of sonic degradation from various sources, including the wire itself. Even on the circuit boards, the copper traces are kept to a very minimum length. The completely redesigned circuit board provides a more straightforward and direct approach to the signal paths. 

•Warm up function

•Ultra short signal path
•Simplest direct circuit path for purest musical sound and high reliability 
•Minimal discrete wiring for optimum signal propagation    
•No DC servo that degrades the signal
•High quality parts throughout
•Fully hand assembled to insure the highest level of craftsmanship
•Upsampling 24bit/192kHz and on/off switchable
•Low jitter digital audio clock system 
•High precision clock
•6H14 tube (digital output - signal buffer)
•A virtually jitter-free - 1 picoseconds - digital clocking system
•Digital output - S/PDIF (RCA), BNC, I2S, AES/EBU (XLR) & Toslink

POWER SUPPLY
The power supplies have been further refined with new components and enhanced AC line noise filtration. Separate power transformer windings and filters provide total isolation between the CD-mechanism and digital signal. 

•2 separate R-Core / Low noise – insulated power transformer for digital audio signals & CD-mechanism
•Innovative power supply provides a high speed energy delivery on transients
•AC power line filter to avoid noise and hash from entering into the unit.
•6 separate FET voltage regulators 

COMPONENTS
The type of parts used therefore must have a synergistic relationship to the circuit they are placed in. It is this relationship of which type of part to use where, that ranks our products apart from the mass. 

•Selected, premium quality passive components used in all applications 
•High quality grade E-capacitors 
•High quality – RCA, BNC & XLR jack
•Gold-plated industrial grade PCB

MECHANICAL CONSTRUCTION
The high grade aluminium chassis impart a richer, more lustrous tonality with a cleaner back-ground and less hash and grain. All brushed anodised anti-vibration-resonance and non-magnetic chassis’s are fully hand assembled to insure the highest level of craftsmanship. 

•Backlit function buttons 
•Modified suspension system to isolate the CD-transport from mechanical vibrations
•Anti-vibration magnetic integral CD-clamp system combined with dark acrylic CD-cover
•AC phase polarity control indicator
•The aluminium feet are resonance absorbing types
•Metal remote commander

Music has something to do with culture. With a classic drive as the CD-T it will be once again reminded., I can warmly recommend this highly. The Ayon CD-T is a module which brings us closer to the music.
JÜRGEN SAILE

SUMMARY: Overall it can be said that a very homogeneous, organic sound pattern. Very color reproduction with high resolution. The sometimes existing in digital equipment, technical mechanical sound is completely absent here. It sounds easy for music. Coarse and fine dynamics reach a new level. Attributes that have nothing to do with the music itself as space, focusing or depth extent are of course at the same high level. Even when the music plays softly, it will be exciting, you have no desire to ever louder to turn. It is amazing what is possible with the outdated Red Book CD format for sound quality.

EXTENDED REVIEW: The traun is what the people of Ayon! At the present time to bring a newly developed CD drive on the market. And then also with a tube in the digital part! Where but nowadays everyone only downloaded, rips, raps ... sorry latter indeed true, but does not belong here. I want nothing anticipate, but thankfully, the Austrians have dared!

As seen from the report on the Aurender could infer a high quality DAC is not sufficient alone for a sophisticated playback source. Only the perfect interaction of drive or streamer) and D / A converter ensures that not gets lost at the source much.

Now have been several people thought about the topic Data transfer via CD drive. One faction claiming each computer drive needs the data can completely read, no other PC would indeed work program. Sounds kind of logic. If you ask a technician to which is done with the topic very quickly: bits are bits, digital art work either at all or perfect! Perfect sound forever? That seems vaguely familiar! 

For this type of reasoning, the other group has prepared a very simple question: why do my 20,000-euro drive sounds better? Well, why is that now? To answer this question clearly, you would have to compare it with a suitable software each read raw data on deviations. Such programs do exist. But that is not all, the decisive factor is not only the correct sequence of zeros and ones, but also their temporal assignment. For this purpose, a suitable apparatus for jitter measurement would be required in addition. You see, that is very expensive, but everything else was going more in the direction of "Young Scientist". For jitter, the manufacturer, however, makes data: It is an internal jitter of 1 picosecond to; for clarification: In 1 picosecond light travels a distance of only 0.3 millimeters! What we really wanted? Oh, listen to music! 

Ayon Ayon would not, if not some smart idea would have been realized even when the CD-T. One can see the digital output a tube! A Russian 6H14 or equivalent ECC 84. What has lost at this point? The reasoning is simple: Many interference of signal occur on the way from the S / PDIF output chip for DAC, because the generator is too weak for this. Therefore Ayon has installed a buffer in the form of a cathode follower here. Thus, the chip has to control only the grid of the tube, which is easy for him. The tube used in this circuit works without reinforcement, ie acts as a pure impedance converter. Rectangular pulses look extremely clean, cable effects are likely here hardly affect. 

But which tube to take, for this rather unusual position? First of all, a tube of the audio range is out of the question due to insufficient bandwidth. The 6H14 employed here from the old Russian military stocks was used in the radar range. Therefore, it can handle frequencies up to 200 MHz and is ideally suited for this job.

If one sticks his nose into the device, you will find the proven Philips Pro drive, two R-core transformers, one for the supply of the I2S interface, the other for motor servo board, and the remaining interfaces. The conductor tracks are gilded, what you do not see every day. They are now not thought for the lady of the house, but also prevent aging effects due to oxidation. The laser unit is not screwed to the lid, but connected to the extremely stable base plate.

For connection to the DAC of the CD-T provides all kinds of opportunities. S / PDIF (with BNC connector!), AES / EBU, TOSLINK and I2S. The tube is of course only active in operation with S / PDIF or AES / EBU. For I2S connections unfortunately there is no international standard, so that when the contact assignment each manufacturer its own agenda. However Ayon has consequently given in the user guide, the pin assignment. So I use the S / PDIF connection, for I2S I would otherwise incur for my DAC for Irons.

First Count Basie has ran. Count Basie, the master of casual, top cool Piano Game. Sitting at the piano, grins and impressed with its economical chord objections the typical swinging sound of his big band. Without the Basie big band would still be outstanding, but it would the ultimate Something missing. A milestone among the many Basie albums is the 1957 released album The Complete Atomic Basie, the arranger Neal Hefti wrote for Basie and would shape the future style of the band. 

With the title "Lil 'Darlin'", a rather subdued played piece, the crackling internal stress of the big band has to be felt. When the music here only go ripples and the last then turns off the light, then the system can not transmit something crucial. This may be the CD-T, of course not alone, but it must be initiated by the drive / DAC. Otherwise the system would grooving even at a Requiem. .

Another example is Sketches of Spain, arranged by Gil Evans for Miles Davis. The most popular titles on the disc is the Adagio from the "Concierto de Aranjuez" by Joaquin Rodrigo, here arranged for a 21-member jazz orchestra. I'm normally not a fan of jazzy classics because usually comes out nothing rational case. But here is less improvised, it is more a rearranging for another orchestra and of course for trumpet instead guitar. Even with the opening bars can be the sultry atmosphere of the Spanish summer heat almost feel.

Now the muted trumpet of Miles has always been problematic during playback, in some situations, I can not help but think of the dentist. Add to that the huge wind ensemble, which places enormous demands on the ability to differentiate the chain. Here, the obtained to resolution and the color display by the CD-T pays, it provides the best possible information from the CD. The fact is just a poor imitation of the original Columbia Six Eye LP. To date, these CD always ran with me under the heading "due listenable," now I can even make friends with it. 

Scene Change, harpsichord music. The harpsichord is not easy to reproduce because of its overtones sound. Here the string is so touched by a keel and not posted as on the piano with a Filzhammer. 

To listen I have a piece, no retrieved THE piece of Padre Antonio Soler played by the Brazilian Nicolau de Figueiredo: "Fandango" from the CD Soler. This is about a sprawling merry dance which in Spain was very popular at that time, bringing the Father but he is is some problems in the church. The instrument is a replica of a harpsichord of Italian master Roberto and Frederigo Cresci. high resolution indispensable unusual sound - Here is a correct representation of the - for modern ears. And which provides the CD-T. The harpsichord is not particularly loud, but sprayed formally before force. You can hear not only the entire harmonic spectrum of the strings are touched, but also how the sounds in the instrument are still dozens of times reflected. The sound comes in fast melodies not go swimming, but always remains clear contours. Excellent! 

So what has changed with the CD-T in the system? Overall it can be said that a very homogeneous, organic sound pattern. Very color reproduction with high resolution. The sometimes existing in digital equipment, technical mechanical sound is completely absent here. It sounds easy for music. Coarse and fine dynamics reach a new level. Attributes that have nothing to do with the music itself as space, focusing or depth extent are of course at the same high level. Even when the music plays softly, it will be exciting, you have no desire to ever louder to turn. It is amazing what is possible with the outdated Red Book CD format for sound quality. 

Did I forgot something? True, there is still an upsampling function to 192kHz / 24bit, which can be conveniently operated via remote control. However I have heard no significant change here. Speaking Remote Control: The one could use as a melee weapon due to the sheer weight well. 

STATEMENT
Music has something to do with culture. With a classic drive as the CD-T it will be once again reminded..... I can warmly recommend this highly. The Ayon CD-T is a module which brings us closer to the music.
