Interesting -- when I switch to USB input, the hiss diminishes significantly. What I get instead is a faint digital "crackle" that becomes louder when I touch the volume knob. Like this hiss, it's not audible when music is playing. Weird. Maybe it's me. I don't have another source available at the moment, so no ability to see what happens when I switch from the VDA-2 to another RCA input.

Edit: When I remove the RCA plugs and turn up the volume for that input, there's no hiss. But the digital crackle (not sure what else to call it) is there. Faint but unmistakable when there's no music playing. So the crackle has nothing to do with the DAC itself. And the hiss presumably has something to do with the input from the VDA-2. As my earlier comments indicated, however, this really doesn't bother me too much, even if maybe it should.
