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

As I read it that Audioquest Jitterbug device is for use with USB DAC connections, not USB drives, which makes sense. 

Lol read https://www.audiosciencereview.com/forum/index.php?threads/audioquest-jitterbug-usb-filter-review.10... take on the Jitterbug...

Please forgive my ignorance but if software such as Audirvana loads songs or albums into RAM before playing, doesn’t that eliminate any lag or latency?  Doesn’t that mean that SSD storage vs NAS storage both become irrelevant and both would be better than streaming?

Uber to keep this less contested, when you visit Seattle this summer remind me to do a test listen with you of Jitterbug in the Unitiserve with SP-DIF into the DAC
there will be Pinot and smoked salmon, of course the Trollers ( pardon the pun ) will claim no double blind differences between farm ( ugh ) and wild fish ( yum )

Dude,

Oh well. At least he tested the jitterbug in the right place where a reduction in jitter might matter. Unfortunately there appears to be no useful effect.

Tgris,

Most streamers do buffer data in memory to isolate the D to A process from any minor temporary variations in bits per second but jitter can and usually does still get introduced to the signal between streamer and DAC for various reasons so its up to the DAC to deal with any jitter introduced into its input signal and more and more modern DACs do just that by re-timing the digital signal just prior to conversion to analog.
