Any competitors to this product:

?

Any comments on the above?

THD = 10%? At 25 watts? You can't be serious...?

The idea was to have external mosfets, with a cheap-ish driver. That
way, if the mosfets blow, or need extra cooling, action could be
taken.

I kind of liked this:

but then I noticed the Patent they have on it. d'OH...

There used to be the analog class D ICs from Zetex and few other
vendors, however it seems like everybody went digital.

0. It works.
1. It is specifically made to force you to use DirectFETs.
2. It is quite tricky to make it work as good as advertized, however it
is possible.

DirectFETs, eh? So no IRF530s, even if paralleled?

I don't suppose it's possible to use something like this to drive
external mosfets (instead of speakers directly)...?
