Class A amplifiers - which are considered the best


I have heard Accuphase makes the highest quality pure class A amplifiers. Wanted to get some feedback on folks experience with their amps and any other amp manufacturers that would be in their league (or better) for class a amps. thanks

This is correct the bias on a true SET amp increases and decreases the power (watts) and it stays class A. And then there's Class A1 with SET's that's another kettle of fish.

But what you said about Vick's amp was
"vicks,Your amplifier is 'single ended' with the KT88?"

And I said "no I think it's a hybrid of some sorts that acts like single ended."

Hi George,
Reading the amplifier designer`s description says it`s made of 6 seperate 'single ended'(not push-pull) KT-88 all connected together and divided into two monoblocks.
Actually to be correct the design is 'six amps per side' for a total of 12 single end amplifiers.
Regards,
I'd like to see the circuit when and if he publishes it.
Just noticed it also says it is run in Class A1, not Class A. Some tube gurus say the extra couple of watts gained from Class A1 is a backward step, rather a couple less watts and pure class A. I don't know never compared the two. It's getting good press and got all us talking about it.
I built a copy of the SET DHT Wavac MD805m mono blocks once no expense spared for transformers, complete with 300b driver and interstage transformers to the 805 RCA tube, the better I tweaked the circuit for sound, the closer I got to to one of my Class A water cooled solid state amps, in the end I stuck with class A solid state.

Cheers George
George ,
You certainly could be right about the class A vs A1 distinction. The designer does mention he`s able to get 21 watts per KT-88 tube as opposed to 18 watts per tube.Is there really much difference between the two types of class A ? I`d love to hear this very unique amplifier.
