Aragon 4004 mk2 vs Adcom 555 mk2

Which amps in the Adcom line were designed by Nelson Pass?
I had the GFA-5500 and I enjoyed quite a bit...The McIntosh amps that do not have Autoformers, I dont believe they have that "Mac" sound...

I think only the 5802 was designed by Pass?

I used to own an Aragon 8002, and it definitely sounded better than my friend's Adcom 555 and 5000 (the replacement for the 555?).

And what is this with the dual mono? The left and right channels of the amp shared on the chassis, transformer and powerplug. Does this still qualify as dual mono?

Actually i have no idea of the benefit of the dual mono design over the stereo design while sharing the same chasis and ac plug. I only brought it up as comparing the 2 amplifiers in question. Common sense tells me there would seem more than likely to be a better seperation between channels however small that might be. As to sonic values i have no clue. Another reason for the thread :)

seems the price is getting pretty darn reasonable on that new amp you were talking about.

Jsujo...I think your on to something. My Mac did have the autoformers.Maybe this is what I was hearing.It was great for speaker protection but not for sound quality! I admit I don't like the sound of Adcoms on 100v2 Paradigms but hooked up on some Maggies it's a different story!
