Sure, bit lightweight, but more than enough for this job. Overkill competitors were not remarkably different, and this is one of those cute senior citizens.
OPPO Sonica DAC
The DAC, the whole DAC, and nothing but the DAC (Sonica app is long-dead).
Korg DS-DAC-10R
Fun because it looks like a swanky little Apple product ( #convo_piece ) but sounds enough like other decent DAC’s.
Yaqin Audio MS-22B
Phono stage with the Les “mods”, 3x 12ax7 Full Music’s.
Phono = phun over phidelity in this setup, so no worries!
Raspberry Pi 3b+ ; 4b
One or the other model depending on what I’m up to, either/or with “official PSU” (gasp away) and Wicked Aluminum case.
I live near a hifi store that sells Gallo, and have enjoyed their sound. And Pierre Sprague from Mapleshade was a big fan, especially of their subs. But you have taken this to new heights, literally. Sounds like you were in an experimental mode - what were the questions for which you are trying to find answers? Is this interesting arrangement giving you any of those answers?
