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.

Sold my Pass X150.5 and regret it almost daily. Back to separates here as well, now using a McIntosh MC275 amp with an Audio Research LS3 pre. Pretty darn good, but the Pass, IMHO, beats pretty much everything else out there. I'll be getting back to Pass shortly - have you heard of Reno Hifi?
  • Sony Stereo Amp from the 90’s (inherited in 2012)  
  • Emotiva UPA-200 (2013)  
  •  Peachtree Audio Decco 65 (2014)  
  •  Rogue Audio Cronus Magnum (2015)  
  •  McIntosh MA6500 (2015) 

Really like the last 2, but if pushed, I’d take the Mac.
