Class A vs AB vs D amplifiers

There was a tube AVR at the very beginning, I don't remember the brand.

The very beginning of... what? ;)
I mean, harmon/kardon made the first widely-marketed & purpose-built integrated power/pre-amplifier and tuner. Monaural, of course (or "1.0" in AVR-speak). Most preamps in those days had a "TV" input -- so AVRs they were! :cool:

h/k also claim to have marketed the first stereo receiver (the MA-230) for all of your "2.0 receiver" needs. ;)

Hi all
Iv always been under the impression that class A AB amplifiers sounded better than class D , however less powerful at same cost etc..
Now days with modules like the purifi , some say the class D exceeds the latter classes... in what respect are we talking, and how does this relate to
sound , detail , low background noise , channel separation, and imaging...
Ive heard the terminology Grainy withe older class d amps.. is this now changed?
thankss!
Try class G and H
