High Speed USB DAC?

I would post your question to Chris Connaker on the Computer Audiophile site that he runs. Either he or one of the many members of that site I am sure will be able to help out. http://www.computeraudiophile.com

Thanks Cmalak - great suggestion. I've been to his site many times.

Related question: anyone know how to change which device is on the high speed bus? Simply swapping sockets and restarting did not do it for me.

Thx,

John

The problem is not the computer. The Mac mini has a USB 2.0 USB bus which is considered high speed as most computers do since 2003. The problem is that the DAC may only be using a USB 1.1 USB input receiver and or software or both. The perfect example is with Ayre QB 9. The original QB 9 was limited to 96K once they were able to either change the USB input receiver or upgrade the software and or both they now were able to make their DAC sound much better regardless of digital format i.e. High Resolution or standard CD resolution the difference is immediate with their new improved high speed USB input receiver. High Resolution still sounds better than standard resolution it is that now that they both sound much better because the faster the data flow between the computer to the DAC thus better bandwidth. The newer QB 9 DACs are now capable of higher resolution than 96K with 24 bit words. I think they are now capable of 192K. I have heard both and in A-B comparison and newer QB 9 sounds better, than the original and I do not know for sure but from what heard they only changed the USB input from USB 1.1 to USB 2.0XX
