Braro, I think one of my JC1's had something similarly wrong; however, mine just stuck on red. That said, the amps played fine, but my nervosa got the better of me and I sent it back to Parasound to fix. It was a simple voltage clamp that was undersized...they charged me nothing except return shipping and I had it back in less than 10 days. I would say from my experience that the customer service was outstanding...and I'm the 2nd owner.
On the subject of this thread, unfortunately I have never heard a Bryston amp so can't offer any insight there. I have heard the Magnepan MG3.6's driven by both the JC1's, the Pass X600, and the McCormack DNA2 with Rev A mods. In my opinion, the X-600 was a large step down from either the JC1's or the McCormack...I really did not like the sound of the X-600...veiled, thin, and despite the power rating, it sounded less powerful (keep in mind these are relative statements and may not apply in a totally different system). The McCormack and JC1's were much closer, though of a different flavor. The JC1's are extraordinarily transparent and I feel extended on the highs. The McCormack was a little better in the low frequency weight (not by alot), had a slightly better "bloom" in the midrange, but also sounded darker or more closed in on the top. Both are fantastic amps...I preferred the JC1's in my system.
