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.

Rotel 1080 nice but it kept blowing out a channel
Parasound A21 very nice with a little warmth
Pass Labs XA 160 not quite my cup of tea
Ayre MX-R...hopefully done for now!!!!!

1) Sansui (integrated, can't remember the model designation)
2) Luxman L410 (integrated)
3) Audio Exclusiv P2 (pre) + Luxman M363 (power)
4) The P2, an award collector in the early 80s, was the first used gear I bought; impressively as its musical performance was - especially phono - , it soon showed it had really been used ("worn" rather) and needed to be replaced by: T+A P1200R (pre) + Clearaudio Basic (phono)
5) Thereafter I ventured into surround and replaced the Luxman M363 by T+A A1520 (2 channel power) + T+A DD1510 (decoder + 3 channel power amp)
6) Replaced the T+A 1200P by T+A 1230P (huge change)
7) Replaced the Clearaudio Basic by Quad P24 (tube phono)
8) Dropped surround altogether and replaced everything by Tidal Preos (pre including phono) + Tidal Intra (power)

second system
1) Unison Research Unico SE (hybrid integrated)
2) Unison Research S2K (single ended, class A tube integrated)
Sansui model 400 receiver
Marantz model 1120 int. amp
Pioneer Spec 2 amp
Marantz 2330 receiver
Marantz 1250 int. amp
Phase Linear 700 Series II amp
Pass Labs X250

Used the 1250 as a preamp with the Phase Linear. For some odd reason I decided to get a nice preamp (Classe DR-5) to use with the Phase Linear. I wasn't prepared for the drastic improvement! Then I had to see how it sounded with a nicer amp (Pass Labs X250), so then I had to.... you know the rest....
Musting be getting a bit senile. I'd have to do research for some of the model numbers. Anyhoo here's the list (integrated where indicated)

1977-78 Sansui Model ? (little integrated guy)
1978-85 Onkyo A-10 (integrated)

1999-92 Dynaco ST70i (Van Alstine Mod)
