OPINIONS: solid state amps under $2000

Symphonic Line RG-1 or 2nd the Belles/Power Modules.

you could look at some of the older Classe gear such as the DR-9,10 and 8 series. They are well built and the sonics are excellent with Classe service being excellent to. You will have money left over for any other upgrade, or just more for software.

Blue Circle CS. You can get it new well under your budget. Don't let the low price make you think it's not worthy.

Perhaps, telling us about your "second system" might allow us to offer you appropriate advice.

Linar 250i
Linar Class A design

I use both of the above.
Not much advertising, does not play the magazine advertise/review/headgame. Victor Sima (owner and designer) was the founder of Simaudio -great guy to talk to, accessable, and will answer all questions if you call him.

Smooth, extended, lightning fast, nice sound stage and natural balance. I believe if these amps were advertised, and were saturated to the public, they would easily double their new price.
