My amp has no faults

"The ability to listen to music comfortably at more realistic levels is THE luxury of high end."

It is certainly one in my book.

Getting good sound all the time at higher levels is one of the things that justifies spending a bit more on speakers that are up to the task and teh amplification needed to make them sing.

Atmas,

Vic Damone said it originally above and I agree 100%.

I can't really fault the bel canto ref1000m amps i use. The only ones i have ever owned i can say that about. The old tandberg came close.

Of course only possible with the right match of speakers.

Would high power consumption, low efficiency or generation of a lot of heat be considered a "fault"?

Those are clearly measurable attributes of an amp.

Not all that determines the sound heard is measurable or accounted for by specifications. Even then much that can be measured does not alone determine performance. So the final determination of what constitutes a fault or not is of course highly subjective and debatable.

"They like them because it is easier to get a tube amplifier to obey human hearing rules than it is with transistors. "

They also look way cool!
