Thread about this on asr. Search "Audio stutters with USB Dacs on Macbook M1 Pro".

It does have a nice amp.  I was just suggesting that, if you decide to upgrade at some point in the future, try another amp and just use the shift as a DAC (line out mode).  The aluminum around the sides is a band covering the sides of a plastic box; I took mine off to tweak the mini-USB port...

Back in the day we called LISSTs "tubesters" or "fetrons"...  really!  I'm old.

Subwoofer?  HiRez music?  What are you using for playback software on your PC?  And headphones, if you like to listen that way...!

Long time reader, first post!  Tremendous wealth of info here, made me move from NO music for the last couple of decades to full-on "ear-fi" listener.  Based on the recommendations here, now have:   1) portable rig for work: an ifi iDSD nano connected to a Firestone Fireye HD amp with an...
