Amplifiers and Horn Loudspeakers


Greetings,

Wasn't sure where to post this (Amps or Speakers), but here goes.....

Horn loudspeakers of course are high in efficiency, and don't tpyically require high-powered amplifiers. Most horn users prefer tubes. With highly efficient horns, folks seem to prefer SET's.

Some solid state amps operate in Class A up to a certain point, which is said to be close in some respects to the sound of tubes. I have a solid state amplifier that puts out 250wpc (Class A/B), however it operates in Class A mode up to 25wpc. I'm curious if this amplifier, operating in Class A mode, would be a good match for a high efficiency horn system.

Thanks!

My Klipsch speakers, both KLF-20's and Chorus II's, sound very good with my Plinius 8100 (int. SS). I will tell you that they sound even better with my restored Eico HF-81 (int. tube).

Hope this helps,
Mike
I think you will find that most amps with specs like you state for your own will, in most cases, employ undesirably large amounts of negative feedback, a sonic no-no IMHO.

When I first got my A/G Duos, all I had in house was my Bryston 4B NRB so that's what I used 'til my Atmaspere M60s came in. 250 watts/ch, claimed to operate in class A up to about 15 watts and definitely swathed in global NFB. Great for specs but not so great for purity of sound.

The operational amplifier is used in almost every piece of analog circuitry under the sun. Operational amplifiers are employed in circuits using negative feedback to increase their linearity (accurately represent the input signal). The audio that you listen to has been recorded and mixed in studios and often mastered in another studio....the audio signal has literally passed through 100's of feet of wire and 100's of amplifiers, all with negative feedback, by the time it reaches you on an LP or CD. If negative feedback were even slightly audible then you have already lost the battle for good sound when you leave the record store with your purchases tucked under your arm!
SS with horns is OK....if you want to rip your ears off!!
I am very carefull with horns and tubes!
Shadorne,

Why do you think it is that amps with zero or very little negative feedback sound so much better than those with lots? And that on amps with adjustable feedback changing it is indeed very AUDIBLE?
