If you like the MHDT Pagoda idea - (I do)
Non over- sampling
No digital filter
No op-amp
No feedback
You might also consider other amps in that “family”. I think they all use the old 16-bit Phillips TDA1543 R2R chip from 1989. It’s a different sound, some find it “cleaner”. I know I like it a lot compared to others I’ve tried. Most of these are in the $1500 range. My favorite is actually the Sparkler.
MHDT Orchid
Sparkler S512
Border Patrol DAC
Once I stopped comparing and just listened, I fell in love with the sound.
BorderPatrol has a musicality that you just don't get from everyday digital gear.”
