Actually… I have a question about that DAC. I intended to use it as a pure DAC, plugged to my THX AAA 789. But… uh… how should I put it… I might have "accidentally" bought a Fiio M11. I was told that the Fiio M11 can also act as an external DAC, lots of good things, very ‘too good to be true’ stuff. So, just, just hypothetically, that Topping E30 DAC, how does it compare to the Fiio M11 used-as-a-DAC?
