Det stemmer selvfølgelig ikke, men her er en grei forklaring på hvorfor det kan virke slik:
If we have however the Amplifier clipping (or at least coming close to clipping) often throughout a musical piece, we will get a notable pull of DC Current which will pull down the PSU on these peaks. It should be noted that the absence of negative feedback and the usually very soft clipping in singleended valve amplifiers will allow short peaks to overdrive the Amplifier quite notably, without the usual unpleasant side-effects of very nasty audible distortion. The perception is often of slightly reduced peak dynamics, but usually no distortion is perceived as long as the overload is very momentarily. This effect explains the audiophile phrase that Valve (or Tube) Watts are "bigger" than Transistor Watts. They are not. But an overloaded transistor amplifier will "latch up" (go into saturation) and thus take a relatively long time (as much as a few 100uS) to recover from transient overloads. The distortion on clipping is socially VERY unpleasant. As a result even brief peaks that exceed the Power-Limit of the Amplifier (say 50W) will sound subjectively distorted.
