Aragon 4004 mk2 vs Adcom 555 mk2

Ritteri, I have never had my top off so i was just going by this quote from Mondial Designs'
"The true replacement for the 4004 was the 8008BB. However, the 8008 BB also incoporated 50% more output transistors, twice as much power supply capacitance, and the balanced input stage. The difference between the 8008ST and 4004 is that the 8008ST used a single, "dual-wound" transformer for the power supply while the 4004 has the separate transformers. The 8000 series amplifiers also added the DC servo circuit for flat operation down to 5 Hz."

Actaully yes you are correct. I think the 4004 has dual 900kVA transformers. THe 8008BB has dual 1.1kVA transformers. The Palladiums each have a 2000kVA transformer.

Kool39...The photo I saw of a for sale 4004 showed one toroidal transformer. Pop the cover and take a look, or admit it doesn't matter :)

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?
