Is there a time frame for new Cap burn in time. Crossovers were Re-Capped using Audience caps. The company says they are Pre-Burned, So to speak, But the speakers have mellowed out some after about 50HRS of use. I'm hoping they are what they are now, And no more change in sound. They (HPM 100) are much, Much better as time has gone by. Also is it safe now to put some power(Loudness) to them? Thanks, Robert

Different caps can take different lengths of time to burn in. 50 hours is probably enough for most but I've heard of and heard some that were well over 100 hours (teflon ones come to mind for particularly long break-ins).
I've never been easy on speakers because of capacitor break-in.
Sonic caps are between 300-400 hours.

Thanks. Time to use them the way I always have.

I'll be the odd man out. I have never seen any evidence that capacitors, particularly film capacitors, require a burn-in. If a film capacitor significantly changes after, say, 25-50 hours of use, I quickly unsolder it, toss it in the trash and replace it with a stable device.
Film capacitors are not cheese or wine.
What "burns in" is the human brain, and this is referred to in psychoacoustics and elsewhere by terms like "perceptual accommodation".
Many speakers, on the other hand, DO require a burn-in, because the spider and surround undergo a compliance "settling in" with use.

No need to be the odd man out, I'm joinin' ya' here, Fred.
Go ahead and crank those speakers up. Just don't clip the amp. ;)
A quick anecdote on "perceptual accommodation". When I got my Time Windows after listening to the Norman Labs for a while, I thought the high end on the TW's was kind of dull. Now I think the Norman's are bright. Go figure. :scratch2:

I'd have to go with Fred and Mchaz. I feel that "Burning in" electrical devices (with exception to speakers) is a dubious thing.

Thanks, And thanks Fred. Moving the drivers around, Did change the sound. Guess I'm still getting used to the new arrangement.
