So I’ve been looking at some amps as of late - and I ran across the Pass Labs XA series of amps that are pure class A designs. The xa100.5 @ 8 ohm puts out 100watts in class a then goes into a/b beyond that.
The bhk monos on the other hand stay in class A for 1 watt. Both amps get excellent reviews. Can anyone compare the tonal characteristics of the amps and advantages of either design ? I know the pass puts off heat because of the design. That doesn’t concern me.
