Yup. I do understand regarding the oscilloscope waveform of clipping. Besides, as you do know, the clipping could be at the positive of the wave or at the negative of it... or both at the same time. The clipping point is where a DC voltage starts to show, because the amp can not handle more power. When the amp is at a clipping stage, the sound is horrible, but many people does not realize that they are over driving the amp, making (a cone speaker) to heat the voice coil at a melting point. This issue (specially when an equalizer is use as a tone control) gave a lot of work. I did repaired a lot of cone speakers due to the clipping power abuse. Old Martin Logan speakers need a lot of quality stable power to drive them. Because they are not easy to drive, due to their impedance curve behaviour and hard sensitivity, many manufactures like Conrad Johnson, Krell, Mark Levinson, Audio Research Company, Jeff Rowland, Bryston, Classe, Aragon, etc, to name a few, used the speakers that you own as a "tool design". The CLS were at their test bench for design. On now days, the efficiency of the ML speakers had changed dramatically. This feature allows you to use a wider range and brands of amplifiers to drive them nicely. You can train your ears, and beyond. How can you measure the feeling of a musician? How can you measure love or hate? And music as a way to express this. But please do not misunderstand me. I do know what you are trying to tell us since the beginning. It is the importance to have a stable amp, than the one that does not, to drive a reactive load. What I believe, it that the amplifiers, due to their design, sound different, without clipping. Some show better the musician feeling than others. Believe me when I say that I do understand your point! Happy listening.
Hi, Roberto. My desire isn't to get into the subjectivity of why, or even if, we hear what we claim we hear but, rather, to impart the importance of objectively measuring, what is a known component of differing amp sonic characteristics, to those who are wondering.
Again, for anyone who is into ESL's (and ther known penchant as amp killers) I can't stress enough the value in knowing your amp's clipping performance.
