Hi: This statement comes from audioholics ( the TWL link ):****" Another mechanism that most certainly can have measurable and audible effects are response errors due to the frequency dependent impedance load presented by the speaker. The higher the output resistance of the source ( amplifier ), the greater the magnitude of the response deviations. "****.
This is my statement in this thread ( the same that I already post on others threads ):
******" The tube amplifiers can't do it, it is impossible by the physics laws), only can function like an equalizer sound reproducer. All the tube amplifiers change their frecuency response with the changes in the impedance of the speakers and this speaker impedance ( normally ) change with the frecuencies,...."***.
As you can see audiholics agree with Mr. Norton, they speak
on the same subject. ( TWL: I never speak of damping factor ).
The problem with this critical issue is that anyone can hear the high degradation on the signal reproduction.
Now, for anyone can " see " how heavy is that signal degradation: you can go to Stereophile tests on speakers and " see " the electrical impedance diagram where you can watch the multiple frecuency deviation that has the speaker: the tube amplifiers has almost that same deviations ( depend of it output impedance ), only the SS amplifiers can do the job with out that signal degradation.
Regards and enjoy the music.
