Burning in newly rebuilt crossover capacitors

Timlub is spot on as usual. My findings exactly. More volume is better, but just having a signal is at least 80% of it :)

Volume matters some, but not like breaking in a driver.  You are increasing voltage through the caps.  It is more important to just get a signal through them, but cranking does speed things up a bit.  I'm sorry that I can't give you anything more scientific or specific, but I have done this many times and can only say that when I cranked it up and left, things definitely settled in a bit quicker. Not only that,  I've had some caps settle down in what seemed to be 50 to 100 hours and many slowly changed over 400 hours or so.  

MC, why are you upgrading the crossovers on your brand new speakers?  Doesn’t that void your warranty?  I thought you loved the Moabs as is?  Are you just replacing parts with a better grade?

Audio Research has a written warning in the box that some newer preamps take 500 hours to sound their best.

That is due to the odd ball, exotic capacitors they now use.

The older ARC gear when Johnson ran the company had no such warning.

The main difference I have noticed is off vs on. When on they burn in. When off they do not. The only time volume seems to matter at all is the physical drivers. Even then it is more something people say or that seems to make sense than anything I have actually heard. Turn the amp on. Play music when you can. Enjoy.

That is what I will be doing in a few weeks with my 2nd crossover upgrade, this one to Tekton Moab.
