Hmmm, I have the Level 3 Spring with the Singxer fed by an Aurender N100H and it rivals my CD transport for quality of sound. I have been very happy with it. I have to admit that I am curious about the Denafrips Terminator although it is at a much higher price point.

"To me, a DAC is just a DAC—until it wipes away digital glare and opens the listening door all the way, letting me enter the plain-truth wonderments of the recordings I collect. And the HoloAudio Spring DAC Level3 did exactly that. Its sense of undamaged, I-am-there truthfulness let me relax and enjoy my CDs, and DSD and other hi-rez files, with renewed faith in digital sound."
