Non-feedback amplification topology and frequency
Jmacinnis, The issue here is how the amp will drive the speaker if it has no feedback. This article will explain what is going on: http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.php IMO/IME amplifiers that operate without feedback are more musical as they make less odd ordered harmonic distortion. Since our ears use odd ordered harmonics to figure out how loud a sound is, this is arguably one of the more important human hearing rules! The use of feedback violates this rule. However the audio industry does not like to talk about this, and is something that separates the high end audio community from everything else; we talk about it occasionally instead of never :) 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. |
very interesting article. So mass market audio companies are watching out for their best interest buy supressing this information? If they switched to this better sounding amplification, it could ostensibly eliminate many speaker companies and even their own speakers from being useable? Thanks for finally putting an end to this mystery of why my tube amp was sounding dull. I brought it to a shop yesterday and heard it come to life with appropriate speakers. thanks again and very very impressive website. I look forward to hearing some of those amps one day. |
