Class A vs. AB vs. D... can you hear a difference?

I enjoy the Heat of pure class A operation in big class A older amps, keeps my family warm in the winter

Come on Keith come clean I know you live in Memphis Al.

Just how cold does it get in Memphis during the winter LOL

Ones assumes you mean if they aren't put together with coat hangers and bubble gum.

I guess it should be pointed out that I am looking at get peak levels of 105 db. (THX standard)

Hi davehrab, I live in mobile,Alabama, I was being humerous!, However, we did have a bad ice storm here last year that was rare!, we had about a month of below 20 degrees, thats cold to us down here, Honestly, I have no gripes about my amp getting as hot as it does, a none issue for me for the sound quality I get in return, I am happy with, sure there may be better, this is all I need, cheers.

Ngjockey, you have to realize that linear power supply is in reality a primitive switcher that pollutes AC even more. Jeff Rowland designed his latest class AB power amps with SMPS to reduce noise.

this statement was a surprise to me.
can you explain why a linear power supply pollutes more than a SMPS? if it's true, it's certainly contrary to logic....
thanks.
