I had a Topping D90 - which gets fantastic test measurements and uses the latest AK4499 chip. However I didn’t like the sound in my system so I sent it back. I suspect the Modi 3 will sound nicer than the Topping E30, whatever chip they are using, based on better implementation by Schiit.
Inexpensive DAC: Schiit Modi 3 or Topping D30
Any reason to prefer one over the other for use while my Ayre Codex is away for repair? Source is USB from an ultraRendu (Roon endpoint); output from the DAC to an Ayre A7e integrated.
