Can A valve amplifier be both Class A and Class B?

no, thats not what it is

the point is that tubeamps usually have much higher input impedance, and hence works perfect with just a pot/att

and most modern CD have plenty of output

not so in the old days of vinyl and radios, where nothing worked without a preamp

modern SS poweramps usually wont need any preamp either
but their lower input impedance needs a buffered att

Ah, I see. Thanks for the explanation. So would you say that my tube amp would actually work better with just a pot/att.?
