A capacitor burn-in device would have saved me a lot of earache after I had caps in my cd player upgraded to Mundorfs .

I think the caps needed some 300-400 hours to sound good.

The new caps sounded very detailed but polite at first listen. After about 50 hours the sound was very shrill and thin. After a few hundred hours, they seemed to settled down, only to sound harsh again.

I was warned about the long burn-in, but I went back to the dealer anyway to complain about the bad sound! These things had a very Jekyll and Hyde personality while burning in.
yes, sir.  Ive had the same experience.  Dr. J (some of you know who he is) told me that one of his caps would sound great when first installed.  After that it would (back up and you will hate them for about 200 - 300 hours) and he was absolutely correct.  They did and I did.  When they finally broke in my preamp sounded amazing.  It was like a new component.  I was wrong.  There were two very special fabulous components in my system: 2 amazing .22 ufd coupling capacitors that transformed my system.  Like a fool I sold that pre and have kicked myself for years for being stoopud.

So is breaking in a capacitor simply an act of loading and unloading charges?  Does frequency matter?  Does simply putting a cap in parallel to a 60 Hz AC line break it in?  What are the changes?  Does the dielectric change physically or chemically?

    Argh is right you stubborn so and so  :duh :rofl: :rofl: Trying to tell you Engineering types about break-in. Duelunds and VH are the longest to break-in.
   W  have been breaking in caps on a Hagerman Frybaby. 500 hours minimum.
