This is a vintage DAC from a now defunct hi-fi company Deltec Precision Audio (DPA), but it sounds great and retains a very high quality sound to this day. The sound from it is rich and warm - not overly detailed. Very spacious. Takes optical and coax input, RCA output.
In it's day it was a pretty good piece of gear, it sold for $800-$400 over it's lifetime from what I can tell. Unfortunately since Deltec closed shop years ago there's not a lot of info on it. Here's some threads I was able to pull up:
DPA DAC's [Archive] - AudioEnz Forums
HI-FI WORLD MAGAZINE - BUYING GUIDE & REVIEWS - CD CONVERTORS
the Deltec / DPA webpages
From my listening it easily outperforms the Silverstone EB01 DAC, EMU0404, and a NAD 505 CD player as a source. There's clear improvements to the point where even my wife notices if that's any indication
Comes with a Volex 17604 power cord, 14awg shielded.
Some info on the power cord
