yeah, it would actually be outputting from my computer to a headphone amp (used solely because I have it and I like a physical volume knob).

Yeah, that should be OK with what ever. As long as it is solid state, that is to say it doesn't have anything funny going on with the input impedance.

I like physical volume knobs too. The Focusrite I have has two headphone jacks, each with their own volume knob, and another volume knob for the line output.

Maybe me? I always point it out when something has blue lights.

Bluuuuuue.

Speaking of blue lights I owe a thanks to whoever it was that selected the led used on the front if my ADA1000. Its bright enough to confirm its powered but will not draw your attention when watching a show or a movie. I wish I could swap all the led's out to match.
My reciever and amp are right below my screen. Its a little detail but much appreciated.

Thanks so much for sharing, that was very informative.

Very good, Chris. Unfortunately, despite the availability of info such as this, there still exist "audiophiles" who believe in the fantasy that digital sampling is a naive "connect-the-dots" type process and can only approximate the original analog waveforms. They waste effort and money on obsolescent analog reproduction media(LPs, etc.)instead of being able to fully enjoy the wonders of modern audio technology.
