Amir at AudioScienceReview benched the 2 in / 4 out Behringer U-Phoria UMC204HD and it looks to be able to best a boutique DAC more than 4 times its cost. I had to push in a few posts to get this in for testing and I think we are both glad he did.
For $79 shipped you are getting a lot for a little:
His baseline DAC is a well respected iFi DAC2. Keep in mind these are the Single Ended RCA outputs. The balanced outs (TRS) have yet to be measured but should handily beat out the iFi if there are no surprises.
There is a potential that all outputs would stay live and that means you could drive both mains and stereo subs with this unit.
And it has an HP amp
And it has analog inputs for ADC duties.
