I had a pair of JC-1's - used them on the top and bottom ends of Maggie 20.1's and on Gallo Reference 3.1's. I sold them. My experience was that the JC-1's seemed pretty flat - lifeless and uninvolving. Maybe I'm just a tube kind of guy, but my VTL 450's sounded sooo much better. If I were buying solid state, I would look elsewhere. Perhaps Plinius 102 or better, perhaps Odyssey Statos dual mono. Definitely elsewhere.
Parasound JC-1 power amplifier
According to John Curl the Parasound JC-1 power amplifier cannot be improved, because it is already at the pinnacle of solid state circuit design. Of course I could not disagree with John, afterall he is the solid state guru...
But I would address the following (and I hope I will not offend anyone): Parasound is not an ultra high end brand like Mark Levinson, Krell, Accuphase or Boulder. It is rather a mid-fi to lower high end company where cost restrictions are very strong (because otherwise they wouldn't sell their products to the consumers). Because of this cost restrictions they simply could not build the world's best amplifier, even if John is designing some nice circuit for them. For example the parts quality is not very good, because they use cheap off the shelf parts. So in fact is the JC-1 IMHO a very compromised product. John could say that it is the best amplifier money can buy, but because of this cost restrictions it is only part of the truth.
