Wow! Nice. You are the one to set the standard in audio reviews, while my portable amp reviews I have done recently were a little lazy (post too early, then have to add updates as I get more info, so info not all in one place). You took the time to anticipate questions and put it in the review from the start.

I would like to add that my APS V2 cabled D2000 do quite well with the Pico, while the RS-1 are not bad but not exceptional with the Pico.

Did you try the Pico as a DAC pre-amp, feeding a full size amp? I would love to hear what you think about that, as I think the Pico sounds better when it is feeding a good fullsize amp than when feeding headphones.
