I have been reading on rebiasing my KSA200 to run cooler and some say to improve the sound. Any thoughts on this and what bias did you set it at? Thanks Rich
I would think the answer to the question is 'It depends..' 🙂
I assume it's a push/pull that works like an over-biased class AB? Depending on your listening level and speaker load, the amp should basically behave/sound the same as long as it stays in the class A area, so if you have speakers that are an easy load, and don't play loud, a quite low current could sound just as good.
I'm sure there are people who knows this amp better and has better answers.

I doubt it will sound any better with less bias but it wouldn't hurt to make the bias switchable for normal/background listening. Preferably with a remote controllable relay.
Never seen a KSA200 circuit so i assume it uses a simple Vbe multiplier like the KMA and not the multistage bias of the KSA250.
