Parasound JC1's vs. Sim Audio W10

Bob,

Is it ok to turn the JC-1's on and off every day or does it take to much of a toll on them? I prefer to do this but certainly do not want to hurt the amps. Thanks for your responce

Break in time. Bob I am going to have listen one more time to a pair of JC-1's in the next couple of weeks.

What is the minimum play time until these amps will show most of what they are worth and sound pretty nice.

I had a listen to a pair 6 months ago and frankly was underwelmed - they had about 100-150 hours on them and I ran them in for another 50 of so. The dealer in total has probably only put about 300 hours max even now. He much prefers the sound of the moon W5 and has dismissed the JC-1's as he believes the long play time as garbage.

Bear in mind that the dealer is not going to let me play these amps for 1500 hours, and I am not going to buy anything on the promise of fundamental changes in sound at a later stage.

I would appreciate your honest oipen opinion as always.

cheers Shane

Shane,

I know a number of people who have these amps (including myslef), and I am pretty sure all of them will tell you that prior to about 1200 hours, they relly do not shine. After that initial 1200 to 1500 hours they are a totally different amp. Feel free to e-mail me if you want to discuss them over the phone.

Hi Shane,

Break-in time with the JC-1s is horrible as it takes right at 30 days for the thinness to go away and almost 60 days for units to open up. Why? Probably the huge Nichicon caps if I had to point a finger, but not certain........

I have no doubt these are fine amps when the breakin time is up, judging from the great endorsements I have read by so many folks. What bothers me is that should I buy a pair, and I am interested, I will have to play them on average 10 hours a day for 4-5 months before they deliver the performance I have paid for. That is a Hell of a long wait and if they sound lousy during that period, I don't think I would buy them, for that reason alone.

Can you please explain if there is a way to speed up the burn-in,and comment on the sound quality during this period. Will I enjoy my music during this time, or will I get discouraged?When I see these for sale on A-gon, I wonder if that is in fact the situation that has befallen the seller.
Thanks, Carl
