Full-featured Top Loader CD-Transport

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

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 It is amazing what is possible with the outdated Red Book CD format for sound quality.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.

The resolution obtained and the colour representation paid off by the CD-T, he delivers the best possible data from the CD.

STATEMENT  - Music has something to do with culture. With a classic drive like the CD-T you will be reminded once again. For anyone who can jump over his own shadow and in the present time wants to buy a CD drive, I can warmly recommend this. The Ayon CD-T is a building block that brings us closer to the music. 

EXTENDED REVIEW: It is interesting that in today's time to bring a newly developed CD drive on the market. And then with a tube in the digital part! Where nowadays everyone is looking at downloads, rips, raps ... sorry the latter is true, but does not belong here. I do not want to anticipate anything, but thank God the Austrians have dared!

As you can see from the my previous report on the Aurender, a high-quality DAC alone is not enough for a demanding playback source. Only the perfect combination of drive or streamer) and D / A converter ensures that not even at the source much is lost. 

Now many people have thought about data transfer via CD drive. One faction claims that every computer drive must be able to read the data completely, otherwise no PC program would work. Sounds logical. If you ask a technician about this, the topic is also completed very quickly: bits are bits, digital technology either does not work or is perfect! Perfect sound forever? That seems somehow familiar to me! (its absolute rubbish of course).

For this type of reasoning, the other faction has a very simple question: Why does my 20,000-euro drive sound better? Well, why is that? In order to clarify this question clearly, one would have to compare the respectively read raw data on deviations with a suitable software. Such programs actually exist. But that is not all, of course, not only the correct sequence of zeros and ones, but also their temporal assignment is crucial. For this purpose, a suitable apparatus for jitter measurement would then additionally be required. You see, it's going to be very time-consuming, but everything else would be more in the direction of "Jugend forscht". However, the manufacturer gives information about the jitter: He indicates an internal jitter of 1 picosecond; to clarify: In 1 picosecond the light travels a distance of only 0.3 millimeters! What did we want? Oh, listen to music! 

Ayon would not be Ayon, if not at the CD-T some clever idea would have been realised. So you can find here in the digital output a tube! A Russian 6H14 or its equivalent ECC 84. What has it lost at this point? The idea is quite simple: many signal disturbances occur on the way from the S / PDIF output chip to the DAC because the generator is too weak for that. That's why Ayon has installed a buffer in the form of a cathode follower. Thus, the chip must only drive the grid of the tube, which is easy for him. The tube works in this circuit without amplification, so it acts as a pure impedance converter. Rectangular impulses look extremely clean.

But what tube take, for this rather unusual position? First of all, a tube from the audio sector is out of the question due to the low bandwidth. The 6H14 used here from old Russian military stocks was used in the radar field. It can therefore process frequencies up to 200 megahertz and is ideally suited for this job.

The laser unit is not bolted to the lid, but connected to the extremely stable bottom plate. This results in a much better design. The processing is - as usual at Ayon - excellent.

For connecting to the DAC, the CD-T offers every conceivable option. S / PDIF (also with BNC socket!), AES / EBU, Toslink and I2S. The tube is of course only active when operating with S / PDIF or AES / EBU. For I2S connections, unfortunately, there is no international standard, so that in the contact assignment each manufacturer cooks his own soup. However, Ayon has consistently indicated in the manual the pin assignment. So I use the S / PDIF connection.

First, Count Basie has ran. Count Basie, the master of the casual, super-cool piano game. Sits on the grand piano, grins and shapes the typical swinging sound of his big band with his sparing chords. Without Basie, the big band would still be great, but it would miss the crucial something. A milestone among the numerous Basie albums is the 1957 released album The Complete Atomic Basie , which was written by the arranger Neal Hefti for Basie and should shape the future style of the band. In the title "Lil 'Darlin'", a rather restrained piece, the crackling inner tension of the big band must be felt. If the music here only ripples and then the last turns out the light, then the system can not transfer something decisive. Of course the CD-T can not do this alone, but it has to be initiated by the drive / DAC. Otherwise, the plant would groove well at a requiem.
