Could someone shed some light into what the actual benefit of these USB modded DACs is. I have been reading about it but I am puzzled as to what they really do.USB is a token based bus with CRC based packet integrity and retransmits on corrupted packets. The USB audio profile allows for isochronous or asynchronous tranfer with flow control.
In both cases the audio needs to get buffered at the receiver. In isochronous mode the source of the data controls the rate at which the data is sent out while in the asynchronous mode the sink is in control and can completely decouple itself from the incoming data rate.
By adding a USB port to a DAC which of the above options do I get? Do I need to install a special driver on Windows to make this work?
Cheers
