Sean, those warble tones, bass sweeps, etc...I happen to find them relaxing, almost soothing. I am not kidding.
A while back, I broke in some equipment having left it on for about 10 days, at 24hrs. on quite minimal volumes. So minimal, even near field listening was strained. After this time period, I decided to turn the volume up to normal listening levels and left it on again for 24hrs., but for only 5 days.
I found there was definate break in throughout the initial 10 days, but in comparison, the second break in period at real levels provided dramatic improvements.
Thinking about it, this makes sense. Do the capacitors drain similarly at low levels in comparison to higher levels? There is curcuitry in equipment that provides for treble, bass, some excel at depth, others imaging, etc...and we know that you can not always hear these at low levels, so it should logicaly follow that to break in equipment, such said equipment ought to be broken in at levels in wich they can be reproduced.
(O.K., there are those who might say that the second period might in fact just be a part of the extended first, but I do not think so)
