WM..

Fancy a go in my Cube?? It's been a bit bored recently, not made many trips. It's in need of a traveling companion i feel !

Global negative feedback?

Correct me if I'm wrong but surely that was the whole method of the Jap amp manufacturers in the 80's and early 90's that made such wonderfully low distorting amps that sounded like a pile of crap next to the more poorly measuring brit amps?

The only person I know that has had anything to do wtih hi-fi amp design is adamant that the best amps are produced by using a little negative feedback as possible. If the amp is designed well enough it should need much. There is no need to feedback a difference distortion figure if the native distortion of the amp is suitably low in the first place. Something that is more than easily acheivable with current op amp and power transistor technology.
