Absolute top tier DAC for standard res Redbook CD

Matt
What if the DSD is better than the Dac you purchased?

Steve, as we both know, S/PDIF is a very jittery interface when it comes to a Master Clock recovery. Synchronous or asynchronous re-clocking techniques have been long ago implemented to remedy the issue. So yes, S/PDIF can sound really good too.

Guido, the TAS1020 used as an USB interface inside the Aeris is an older chip that cannot process more than 96kHz PCM rates. So maybe this is the reason they prefer S/PDIF connection.

When it comes to DSD-S break-in, I have sent one that had at least 700 hours to a customer in Canada. He claims that it continues to improve. :-)

The other interesting part, if I may add, is that Aeris and ODSE probably use the same Analog Devices DAC chip - the AD1853, except if Steve hasn't gone for the flagship AD1955, but those are the two choices for the ODSE. :-)

So it would have been indeed interesting trying the Aeris with a modern USB to S/PDIF interface, though I personally believe that it still will not be up to the ODSE, IMO of course.

Matt,I did not mean to open up a can of worms asking if a transport was being used in the sound-off. It would have been something that would have been of great intrest to me...seeing that I am old school. Your work is indeed much appreciated and everyone here could agree with that comment. Keep up the great work and most of all...have fun with it!!!

Hey Matt, I appreciate what you have done, and have read all as time has passed.

The USB input for any of these DAC's is the factor that determines the final outcome, using your source. This is obvious. I believe all the DAC's you have tried here are fully capable of being transparent. There are all too many DAC's out there that do not get the USB input right. Even DAC's that cost over $10K.

Being that PC or MAC is likely the main source for the masses, I feel you are exposing this shortcoming in these DAC's, and these companies need to get with it. Not that you are, but don't get discouraged by the few posters here that have not made the move to computer audio sources. They also need to get with it IMO.

Another REALLY great DAC with a remarkable USB input is the Auralic Vega. It is not the newest on the block, and the snobs here will have their opinions of that it is not in the same class.... But they really did get the USB input right on this DAC. Not to mention the DAC itself is just wonderful. I've compared this DAC to many DAC's. MANY! I feel that it would compete and likely beat many you have tried here. Says allot about this company being this would be the cheapest one you have yet tried. The only shortcoming with the Vega are the RCA outputs. They are not using the same discrete output that the balanced outputs are, and the difference here is not subtle. You are balanced so no worries. I urge you to try this DAC, just so you can see what is possible with a $3500 DAC done right.
