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.

From old to new

Sony receiver
NAD 40 watt
Carver m400?
Carver m500
Rotel 980bx
Conrad Johnson MF2500
Creek integrated
McCormack DNA 0.5
MCCormack DNA 1
1. Kenwood receiver (100 wpc, baby cakes)
2. Opera Audio Consonance a120 Hybrid Integrated (sweet)
3. Van Alstine Ultra 550 (hybrid, pure music)

I have no plans on replacing the 550, unless I somehow, unexpectedly, acquire a load of cash, or my wife leaves me for some young, flat-bellied pool boy. I might then want to try a pair of ASL Hurricane 200's. Otherwise, I think I'll be happy with the 550 for the duration.
