New Adcom GFA-555 se - Special Edition

welcome to audiogon Power_hungry. I apologize for misinterpreting your motives and post. Certainly there's nothing wrong with expressing excitement about a new, and/or old product.

I'm looking forward to the new Edsel.

I haven't owned any Adcom products, but I was very, very interested in a pair of Mirage M-3 speakers years ago.

I went to the dealer and listened to the speakers several times (he was driving them with a pair of Adcom 565 mono's).

The amps must have been pretty good....because the speakers sounded outstanding.

FWIW, I used to work for Adcom and I own or have owned one of every non-MOSFET amp made from the GFA-1 up to the GFA-565 monoblocks.

I was curious about this 555se - I cant seem to find any real information on it. How is the balanced input implememnted? The Adcom GFA-555 PRO (and the 565 balanced option) used opamps for balanced operation and they did not sound as good as the unbalanced input. Also, if this amp is a really a hopped up mk II, then it will have a DC servo and capacitor input instead of a directly coupled signal path like the original. The mk II, BTW, is not a Nelson Pass design, it is an "improvement" of the original circuit by two other designers.

I'm a big fan of the original 555 (only when modified), but I'm curious to see if the new Adcom can make this amp as much a value as the original.

Any more news on these? Has anyone actually heard one?
