Personal amp evolution


Seeing the over night success of the speaker evolution thread, it may be interesting to see what type of amp(s) we have all run. Same deal as the other thread-we will sort of create a puzzle of our systems you'll have to visit multiple threads to put everything together!!! ;)
For me I started:
Adcom GFA-565 monoblocks
Rotel RB-990bx
Jeff Rowland Design Group Model 5
Balanced Audio Technology(BAT) VK-60

either a CAT JL2, BAT VK-75se or Tenor 75Wp on the horizon.

got my audio note conqueror stereo 300b single ended amplifier...finally...worth it
my evolution:

sony integrated amp
adcom 555II
music concept mod hafler XL280
Symphonic Line RG1 MKII
Symphonic Line Rg1 MKIII now

I am considering uprgrading to RG4 or kraft 250 in the future.
In order of use and rating based on max of 10:

Carver 705X (6/10)
H/K PA5800 (7.5/10)
H/K Signature 2.1 (7/10)
Citation 7.1 (4/10; note - gave me an earache)
Chiro C-500 (8/10)
H/K Signature 1.5 (8/10)
Bryston 4BST (9/10)
Marsh A200S (8/10)
Innersound ESL (10/10)

The Innersound ESL is as close to a perfect amp as I have found and anyone looking for the best in high power and transparency should definitely give it a listen, and especially if they use electrostatic speakers, but it is great with regular speakers as well.
From first to last and worst to greatest
