Personal amp evolution

2) JVC M3030, a pure class A 30 wpc amp.
3) Forte model 5
4) Aragon 8008st
5) Krell FPB 200
6) Cary V12 signature monoblocks (borrowed from a friend, just wait till I get him back for that!)
7) Krell FPB 700cx
8) I just bought a Classe Omicron here on AudiogoN. SHould be in my listening room by Wednesday. I'll be glad to have music again.

B&K ST202+ Rebiased and fan cooled (amazing sound at 50W class A) cat knocked fan down, amp melted.

PSE Studio IV Euphonic little 120 WPC amp. Great imaging and easy euphonic sound. Detail level amazing with good PC.

Bryston 4B NRB - Great bass and decent imaging. Distinctly "pro" sound from midrange center through brittle treble. Improves a little with good PC. Clips at 95-98db SPL on Magnepan Tympani depending on bass content.

Biamp with the above two. Great match for Tympani. Bryston still clips on the bass at 100-105 db SPL. (lower with passive crossover, higher with active crossover).

Triamping with active crossover

Bass: Crown 5002VZ 2500 WPC at 4 ohms WOW bass. Not good for anything else unless you have the most laid back of speakers - due to thin "pro sound" high frequency heat. Grand imaging though.

Mid: 300hz to 5khz Classe DR-9 Great imaging, wonderfully full and nearly lush upper midrange (with good PC) lacks some dynamics. Images more specific and stable than with the PSE or Bryston 4B NRB)

Bryston 4B NRB imaging not quite as good. More dynamic than DR-9.

Treble: Classe DR-9 smooth and extended, but a little thin clearly outclasses PSE, Bryston).
Bryston is smooth (with PC - stock cord is a joke) but heats the treble as output increases.
