I own an Yggdrasil A2 (before the latest Less is More variant). Also owned a Terminator which I sold for a Terminator Plus. I think the Yggy is a decent DAC for the money, but I've had a friend's Gumby MB over to compare and thought that DAC offered better value (not much different than my Yggy).
Compared to my the Terminator (circa early 2000), the Yggy was a bit more forward sounding with a shallower soundstage. It was also a bit fatiguing after a few hours. I've had the Terminator Plus for a couple years now, so it's been a while since I compared the original Terminator to the Yggy.
The Terminator Plus with Gaia has more detail while at the same time being smoother sounding and easy to listen to for hours on end.
I haven't heard the lower-end Denafrips DACs, but I'm very happy with my Terminator Plus. But of course, its a much more expensive DAC.
