There is something going on with the capacitors. My ICEpower amp has been burning in for about 12 000 hours and my DAC about 23 000 hours. They are designed for 24/7 operation. When I disconnect the juice from the capacitors and connect it back again, there is turbulence when fresh juice starts rushing in. And then it needs many weeks of stabilization for the juice to remain still. When new waves of juice keep entering the capacitor it takes a long time for it to stabilize.

Right......
1 second IS not even enough to significantly cool off any active hot components ( mosfets, transistors, tubes, caps etc.), that takes several minutes at least! And it takes also much longer to completely drain a cap!
Some even 12 hours or more, hence the use of bleeder resistors, to drain the caps immediatly.
Recently i totally moded my amp and loads, and i really mean loads of new caps in there, new cables, new resistors etc. Now, after 300 hours of burn in, the amp actually sound the same when i play some cd's and turn it off again and turn it on again. No changes anymore, if any, your caps will deteriate slowly. I am not sure it is soo good for caps to operate 24/7.
Some designs even have bleeder resistors on the caps to completely drain the cap, if not in use!
maybe it is these designs withut bleeders that benefit from 24/7 operation, since caps will wear because of turning on and off etc.
At least my amp still sounds the same every time i turn it on and listen to a cd.
What type of caps do you have in your amp? oils, teflon?
I've never heard anybody claiming the amp sounding different after a burn in period!
12000 hours! If any these caps are getting worse, not better! 12000 hours is way beyond even for the hardest to burn in caps, like teflon caps wich need at least 500 hours to fully burn in! Oils need at least 250-300 hours of burn in. That's it. 12.000 hours is wayyyy past any burn in of any active component.
It is true however that caps can fibrate, hence most are tied to the pcb, to stop fibration. But i have a hard time believing it takes weeks to fill the caps, it doesn't.
I can hear quite easally differences between cables, amps, turntables and cdplayers but i don't hear a differecne in sound now my amp has burned in completely. it sounds the same every day i put the amp and cdplayer on and listen to the music, the same cd's still sound the same, day in day out.
