Female vocals on particular are masked by high jitter levels. I recently developed a version of my products with S/PDIF output jitter in the 10psec range. Compared to the 50psec that I had been achieving this extremely low jitter delivers much better intelligibility, particularly of background singers. It develops a much more 3-D picture of the vocalist as well.
So, what does this mean for the DAC?
If you use the USB input driven from a computer, the master clock is in the interface, sothe jitter of this is critical. These USB interfaces are all at different performance and jitter levels. If you drive the DAC with a transport, the jitter of this transport is critical. If you drive it with AppleTV or Sonos et , then the jitter of these is critical. These are notriously bad BTW, but they can be improved with a good reclocker.
