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.

Geez, you guys started out a lot higher on the audio food chain than I did. The evolution of my main 2CH rig:
