Power amplifiers with selector Class of operation?

Hello to all,

Would like to know amplifiers that have the feature of select the class of operation, between Class A or B.

Like the Pioneer M-73, Sony TA-N88B, I think there's a Luxman too but can't remember..

Any others?

Thanks.

I never liked switches. Why do so many Japanese power amplifiers and integrated amplifiers " still " use speaker switching ? ( I know this is different that the bias switching being talked about ).

roberjerman, whether you think so, or not, speaker switching, brings the speaker output wiring, to the front, and then, back, to the rear of the amplifier, and, this, limits current, affects damping, and can only add / pick up noise. In your very large museum of power amplifiers, name me one American made power amplifier, that offers speaker switching. Bel, GAS, or whatever. When Adcom decided to eliminate the speaker switching, from the GFA 535, to the series II, this was an enormous upgrade ( other things, positive, changed, as well ). I can only imagine a Krell, Threshold or Levinson power amp ( of which I have owned many ) having speaker switching. Just use a 2nd amp, for a 2nd pair of speakers, or, change the speaker cables, manually, to the other pair. I find many statements of yours, ridiculous. But hey, we all have our opinions....Enjoy !
