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.

Oh wow...
Packard Bell tubed stereo (60's)
Pioneer reciever (early 70's)
Tanberg reciever (still running! mid 70's)
Audible Illusions mini-mite pre and power Kit (1980?)
Various SS amps: Amber,PSAudio, Threshold,Phase Linear,Carver etc(80's)
Van Alstine hybrid,Sonographe (early 90's)
Atma-sphere, Spectral, Bryston SST, Spectron (now)
Present iteration is Levinson CD, feeding Spectral, Feeding 4BSST. By far the best balance of dynamics and tonal color I have ever heard. (No free lunch!)
since my last post on this subject i have,once again,changed amps..this time from the tenor 75 wi's to a goldmund mimesis 29m.this amp does everything the tenors did,and does it as well, but drives my piegas' much more efficiently and effortlessly.i also changed preamps to an audio tekne 'simona' tubed piece which gives a great combo sound.this time,i think,i am keeping this amp 'for a long time'.
