After 20 years, in the market for a power amp

Why not just fix your current amp? Or do you just want something new? 

Will say MOSFET amps sound wonderful to me, have not had the chance to hear any high end Class D, but have not been all that impressed. 

JC5 indeed!

I would definitely call Klaus. I can remember when i had grown tired of my Stratos monos years ago and I called him, as he is always upgrading his offerings. He made me a great offer and said just send them in. So I did and he used off branded Symphonic Line caps, changed the power supplies, changed the point to point wiring, and other stuff that I forgot about. When I got them back I just let them cook for a few days while I was away and when I got back I was very impressed with everything about these things. He builds some of the best value amps on tbe market. I had 3 different guys come over with their high end amps and it was immediate and obvious that there was just more of everything in the monos. I moved these amps into my main system after the mods and they haven’t moved yet. I’m getting a new Don Sachs / Linn Olson designed Raven tubed pre amp to feed these things and I think it will bring these to yet another level.

I’d recommend checking out the latest offerings from Class D audio and do not let the Class D part spook you. 

+1 for Parasound. I recently replaced my A23+ with a Bryston 3b Cubed. One reason I didn't move up to a JC5 was the weight. At 35lbs the Bryston is much easier to deal with for my old muscles. Even the 4B cubed is only 45 lbs. Hard to find another high quality amp below 60lbs.
