USB sample rate limitations

[Martin Prothero]

I would like to ask a rather simple question as I can't seem to find a straight answer anywhere!

I am excited by the reviews of NOS DACs and I am looking to incorporate on into my system. Currently I listen to redbook CD but I also use a portable field recorder that supports 24/96KHz recording and I want to source (make) a DAC that supports this playback.

Is USB data transfer limited to max 48KHz due to the limitations of the oversampling within a DAC and therefore NOS will not limit bit rate or do I need to build a NOS DAC with a SPDIF or Toslink input?

As you can see from the question, I am still a little confused. Can someone shed some light?

USB 2 can do it easily. Times eight

Thanks for the swift response!

So there is no advantage of using optical or coax over USB2.0?

Well coax is typically better sounding, less jitter and no one really uses usb 2 yet.

Oh, I thought USB2 is the current standard and that USB3 is not yet implemented? I have some catch up reading to do...

Either way, this info has stopped my looking to have to introduce another complication to the DAC. If I can use USB for 24bit hi resolution recordings I will let my ears tell me if I can hear the negative effects of jitter - on with the research...
