New Adcom GFA-555 se - Special Edition

Adcom is making a new version of the GFA-555 II, the GFA-555 se. This amplifier is essentially the GFA-555 II with slight improvements including balanced inputs larger capacitors resulting in a better soundstage and an even higher damping factor. Did you know that the GFA-555 is likely the best selling piece of hi-fi equipment ever made, with a build of over 100,000 units? The GFA-555se will be available sometime in November.

Jim,
Good to read about you positive assessment of the SE version. Keep us informed as it breaks in.
Thinking about the Class A rating, the amp could also have a Class A input stage then AB after that.

Minor update: While chasing ground loops -I gave the balanced inputs another chance.Not sure what's changed - but I am now very happy with what's comin in thru the balanced inputs.And at least i don't have to waste time with poor connections on the RCA side of things.

Stonedeaf,
I'm curious, what does the rest of your system consist of?

I've had a 555 - original model - for more than 20 years. The only problem I've had with it is the power switch is in the On position.

It ran a pair of MGIIs and now a pair of Paradigm Signature S8s. It sounds fine - I've never had any complaint with it.

A truly amazing product for the money.

Have added a pair of very old B&W 801/series 80's ( first generation -not ported-no matrix) and the pair of GFA-555se's run bridged.-for CD use either a old Sony DVD changer or even older Marantz DR-700 fed into Benchmark DAC .Analog stuff is what i described in my 12-16-09 post.Oh yeah and I've got one of those great Sony XDR-f1HD tuners and some video stuff fed into a Marantz pre-pro - then out thru a state of the art seventeen buck RadioSchack A/D converter into the optical input of the Benchmark DAC.Not much into the video stuff.
