Any difference in SQ from USB drive storage to NAS playback?

Usb 2 bandwidth is ~480 million bits per second.

Cd resolution music bitrate is 1.4 million bits per second.

No problem. Not even close.

>>>>>Actually neither of those are bandwidths, they’re signaling rates, assuming the numbers are correct which they’re probably not.

Anyone can look those numbers up for themselves  with google if in doubt.

...so Uber looking back at your original question your configuration with uSB connected direct to streamer fits the bill. Your streamer is serving as both a music server and streamer with usb attached so it could produce more noise and jitter that impacts the digital to analog conversion process than a NAS. The reverse could be the case as well, especially with a wired internet connection to NAS, or there could be no difference at all. Could vary case to case, streamer to streamer. The devil is always in the details.  One would have to try both ways to know. 

It would certainly help to know the difference between MHz and Mbits/sec. 😁

Bits per second for cd resolution audio versus USB is what matters.
