Why all these JC-1's for sale?

5) The amps aren't performing up to snuff due to a lack of available current i.e. each should have their own 20 amp AC line. As such, they blame the amp when there are other problems.

I have not had any problems with dynamics running a single 20-amp service shared with all components and the two monoblocks.

6) The heat and power consumption of these amps are more than they bargained for.

This is a function of the biasing. If it is not adjusted correctly, one amp can get a lot hotter than the other. When I mod these, I adjust the biasing to be matched. This can cause one amp to buzz louder than the other. Once adjusted, they dont get very hot at all. You can put your hand on the heatsink continuously. As for musicality, these dropped from being my references after I modded another amp which outperformed them. However, this summer, I found the time to mod the JC-1's and they have regained the reference status. Have not heard a better amp, anywhere.

Steve, all amps in a run (100 units) are pulled when they arrive at Parasound and are checked for a number of parameters including bias......You stated elsewhere here it took a month to break these in and others have reported it took almost two months for them to open up.....The thin sound goes away at a month and you think there are done as they won't be ready for prime time for another month......

If so, they don't know what they're doing when they check them. I had to return one amp recently because it ran significantly hotter than the other--new, straight out of the box.
I still have them as a back-up. The hard-sell on these amps is absurd; they're excellent value for the price, no more than that. The idea that they can trounce amps much above their price range is laughable.

Audioeng, i bet guys at Parasound are very happy about your mods?!

I have not spoken with Richard since I modded them. He's a good egg. I doubt if he cares much. Besides, if it sells more amps, then it's good for him too.

Bob - you should come to my room at THE Show next Jan. and hear them. You will not believe how good they are...You and Curl did 95% of the work and I only had to do the last 5%, so you guys get most of the credit for this.
