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...)
