Inexpensive DAC: Schiit Modi 3 or Topping D30

The new Topping E30 at  $130 uses the AK4493, either one would be fine. 

+1 for Topping E30 - it bests D30 in measurements and costs only $30 more. It also has remote, volume control mode or DAC-only mode (fixed volume), input-sensing auto on/off. D30 uses Cirrus chip, where E30 uses AK4493 (better chipset) - as @djones51 said above.

All this makes it more usable for other purposes (computer desk, office, etc) when your units comes back from repair. 

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.

Schiit modi 3 uses the AK4490 which is a good chip not sure how much design went into a $99 DAC . I doubt in a blind test a difference could be heard between the two DAC just get the cheaper one with the features you need, inputs etc..
