Non-feedback amplification topology and frequency

Dracule I see this feedback issue hit a nerve as you started a whole new thread about essentially the same thing as this one. I'm quite ok now with Atmasphere's description of the facts and history of this topic. It is up to debate only whether or not you subjectively like the sound of what comes from feeback or not, and isn't that just taste in the end? I prefer vinyl because of the way my ear reacts...it sure isn't the highest quality choice in terms of specs. My original question was just, Do you need to be more carefull when selecting speakers with non feedback amps. Answered.
Today I am the happy owner of a beautiful pair of Cantons that are fully engaging and blow my old system away. It would be fun to play with the feedback knob on your amp though :)

"Ultimately you have to be more careful of your speaker choice; this is doubly important because a speaker that requires the amp to have feedback will never be able to sound like real music- it will at best sound like a good hifi."

Absolute statements like this are bound to hit some nerves. That's what helps create discussion, which is usually where a more complete story might become apparent.

Mapman, they do, but even in high end audio we have to deal with facts occasionally :)

The reason I made that comment is that an amplifier that violates one of the most fundamental rules of human hearing will never sound like real music. Its not so much the failing of the speaker as it is the amp.

"The reason I made that comment is that an amplifier that violates one of the most fundamental rules of human hearing will never sound like real music."

Is it really so black and white in practice though which designs truly "violate the rule" and that use of NF means a violation in all cases?

I would think it more shades of grey with the devil being in the details: the relative magnitude of the violation (which varies and should be measurable) and at what point the "fundamental rule" is "violated".

It really is that black and white. Sort of like being pregnant.

What is poorly understood is our ears are so sensitive to odd orders that we can hear things that cannot be measured. So it might look 'OK' on paper and our ears say something else.

And there is nothing we can do about it. Our ears are the product of millions of years of evolution. Its not going to change just to suit our inadequacies of design.
