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.

No the JC-1 is probably not the best solid state amplifier in the world. It is pretty good for the money though. It does get pretty good reviews and most reviewers agree that it gets you pretty close to the top for a real world price. I personally own a pair and have compared them in my system with many other high end brands and ended up choosing to keep the JC-1s for a couple years running now. I'll agree that Parasound doesn't get the respect as a high end company like some of the others but the JC-1s would probably cost a lot more if they had a Krell or Levinson box around them.

I think a lot of designers and companies claim their products are the best in the world. There is no such thing as the best.

May I ask the point of this? Have you auditioned the amp in a double blind test against some of the other amps you mention, and have audibly heard a difference? Or is this just pure speculation?

Chris,

Where is John Curl quoted as saying "the Parasound JC-1 power amplifier cannot be improved, because it is already at the pinnacle of solid state circuit design"?

Rydenfan: I'm only saying that an amp (in general) could not be the best sounding if the manufacturer is skimping severely on parts costs even if the circuitry design is SOTA. This is a fact whether you like it or not. I'm NOT trying to say the JC-1's are bad!

Sonofnorway: somewhere in the DIY forum someone asked if the JC-1 could be improved and John mentioned that in fact the JC-1 is already a "finished" product. He even mentioned that replacing this of that part inside the amp would not yield further improvements. Go ahead and read the discussion yourself. I'm not lying.

Steve Nugent at Empirical Audio found a way to improve his personal pair. Modding doesn't always make things better, but he has about a dozen changes in his "Turbomad", some of which John Curl seems to have suggested.
