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.

Marantz 2230 receiver

a long pause
Adcom 555II

Berning ZH270

And now the high end:

Coda Technologies Amplifier 20
Coda Technologies System 100
Air Tight ATM2

Accuphase A-50V

Carver M400 (cute cube)
Carver M500 (still have, runs whole-house audio)
Adcom 555 MKII (until a few months ago)
Aloia
Aloia x 2 (vert bi-amp)
Yamaha CA 410II integrated (first college system circa 1977)
Harmon Kardon HK4700
Yamaha A/V integrated ( early model just awful)
Adcom 545
NAD 2100
Hafler 9500 Transnova

I have had the Transnova for over 8 years. I am currently lusting after a conrad johnson amp since I have a c-j preamp, but won't be in the budget for years. New baby and one starting college :)
