lazy and looking for a kit

does anyone know of a kit that does either of the following:

a pre-amp that accepts at least one six-channel input along with a few two channel inputs.

a multi-channel amp with output > 70 watts.

I know these things aren't all that tricky to design yourself, etc, but I really just get a kick out of soldering these things together. I'd really like to get something in a nice case, but I can order on if nec. Any help would be really appreciated. I've built by own two-channel system (mostly assemblage equipment) and I'd like to accomplish the same for a home theater set up.
