Audiomax,
Thanks for the suggestion of using a volt meter. I'll see if I can find one at Radio Shack.
Stan,
I'm in touch with Kent at Pass. So far, he's pretty baffled, too. Contacted PS Audio, as well, and they haven't a clue.
Audiophile,
I tried scenarios using single-end as well as balanced (when possible). Everything seemed to function either way. So, RCA from GCPH-to-RCA into headphone amp was OK; balanced from GCPH-to-balanced into power amp, also OK.
