Aragon 4004 mk2 vs Adcom 555 mk2

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!

I'm the owner of the Aragon 4004 MK II with current pictures and actaully if I remember there are two transformers, stacked. As I look close at the photos I took I'm even more sure of it. I too have owned an Adcom 555 and do prefer the Aragon sound to the Adcom. Just an opinion. My favorite is my Bel Canto EVO 4, thus the Aragon sale. BTW the Adcom sold for $350.00 and all the 4004's on AudiogoN are at $750.00. I'm not sure where it'll finally sell at but I'll keep it for a hood ornament before I go down to Adcom prices.

If the toroidal transformers are stacked that could explain the disagreement.

By the way, think that the Aragon amp costs more than twice the Adcom price, so it ought to be better.

My Adcom 5503 (like a 5500 but with three channels) is hooked up to Maggies. Although Maggies are often called low impedance speakers, they actually are a very uniform 4 ohms regardless of frequency, which makes them an "easy" load for the power amp. Maybe that's why you can get good results with a less exotic (expensive) amp. (But they do like lots of watts).
