I am trying to build a USB sound card and trying to finalize the

I safely take that PCM2706 USB-I2S conversion will not alter the
following parameters before passing the digital audio to the DAC.
(assuming no jitter)

THD+N
Noise Floor
Dynamic Range
SNR

That should be OK, however, you will need data buffering to deal
with the bursty, discontinuous nature of USB.
