Class A Power in A/B amplifiers?


Is there a general industry standard for the amount of Class A power in Class A/B amplifiers?For instance SimAudio has always touted that they run Class A for the first 5 watts.Curious how other higher end manufacturers approach this..

Emaillists, I don't get hung up on the claims; too many times in the past they did not result in superior performance. Evey manufacturer has a claim, an angle.

It's the amp you don't see coming that blindsides you.  ;)
Fascinating thread here. OP didn’t know how loaded the question was. 
The Pass Labs designer’s write up is excellent. I don’t know where this video is at the moment, but an interview with amp designers had John Curl: the question was, “how much bias do you use?”

”As Much as I can.”

- and back to the discussion of the balancing act between too much heat & distortion and SQ/ cost.

That's just the honeymoon period.
My Krell K-300i has Class A for the first 90 of 150 at 8 Ohm.
My CODA #8 Version 1 is the first 18

George - yep, and the old torch bearer is yapping at my heels! Eeeek!

Yeah I got bored over at the other place, much more fun over here, for breaks giving **** to the snake oilers and voodooist like fusers, etc etc.
That sort of snake oil stuff is kept under control over there, so there no real dog fight action.
But I must admit it’s starting to become chronic here, as too many can see 10000’s% of profit selling re-badged 10cent fuses for >$150+ and having no overheads doing it!

Cheers George
