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.

Time for an upgrade on this thread;

Fisher Receiver- not one of the classics :(
Sansui Receiver- worked great and got me through college
NAD3140 Integrated - a classic, still powers my 2nd system
NAD2150 Bridged w/3140(still works great)
Adcom 5300- thin and strident, one of my least favorites
Acurus A250- one of the better lower end choices
Acurus A200- actually preferred the older A250 by a little
Aragon 4004MkII- a very nice ss amp for the money
Classe DR25- more refined and musical than the 4004MkII
McCormack DNA 2- outstanding bass, otherwise unremarkable
BAT VK-500- nice mids but not as good at the extremes
McCormack DNA 500- the best I have heard, nice midrange, juicy bass, musical across the board, and never runs out of steam. I am sure there is better, but I suspect the price of admission for a noticable upgrade would be large (the CJ Premire 350 looks tempting though...)
