On Belles vs CJ: Believe it or not at 4k vs 10k imo the Belles is the better amp.---To back track: I only had the Belles for 12 days / I have run the CJ ever since. It is a nice amp to be sure/ oh, I guess dependability should count. The first 3 days with the CJ, I was bummed. I have since spent 9k.---This is true. First I upgraded my dig. cable---That helped a bit. But that wasn't enough. I bought the AA Prestige se player and have glorious sound I never had. ---If anything it shows the importance of a high quality source.---Which we all know about but an upgrade like this reminds me of things we know but need a wakeup smack to remind us / or at least me,I needed it.
I would say the amps sound similar in many respects. I would say the Belles gives you just a bit more. That "bit-more" I mention, IS WHY we spend big bucks---just to get that bit-more. The amp makes the music come out of a blacker background.---Which I mention in another post as the amp appearing to be quieter.---The highs have a 'bit-more' sparkle.--The soundstage a 'bit-more' deeper/ wider. Midrange is hard to say one being better than the other. Just a taste better bass---not by much.
I have a yardstick I measure audio upgrade things by: When I can't turn the system off; I'm in heaven.---Which describes that 12 days / with the Belles. The CJ got turned off on schedule,period. NOW; with 9k more invested, I'm at that same point. I am sure there is a reason why there are 3/4 of the 350a ref. amps for sale. BOY, and are they cheap. When I bought mine it was the only one listed. I would say to anyone: Think about buying the cheapest used one and send it in for the "soft-start" board. Depending on where you live/where the seller lives and David is on the east coast----Maybe have the seller send it to David???? At the price I don't think there is a more refined/dynamic quality/high powered amp. The CJ is a good yardstick on which I base this opinion.
