Wow, Brett and Larry, the Home Audio Furnishings Guys. I think it's time you started a show on access cable. This is great stuff.

Meantime, Larry, what kind of problem will I run into trying to fish the same speaker cable behind a wall in a garden-home rowhouse? I know there are cinder-blocks in there (at least there should be) acting as a firewall, and they seem to be fairly close to the drywall, since trying to use anchor-bolts or butterflies often produces a botched job when the screw hits the concrete. Is there other crap in there like paper and pink? ... Mike
