Non-feedback amplification topology and frequency

Thanks atmasphere. That is a plausible explanation why SET amplifiers which almost always employ zero NFB sound more involving (dynamic) than reality. I've found SET amps with zero NFB to be less accurate than PP amps using NFB.

Thanks Atmasphere.

Ralph,

That was a VERY cool video of the Fisher Z-Matic. I'm constantly amazed of what was done...back-in-the-day!

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.
