That certainly is of some help. The only issue I'm seeing is that the Polk products connect via a single optical cable. It appears that they're designed to just be used with a TV, and not with a receiver. I haven't seen many AV receivers with optical out like this. I could ditch the receiver and just go with the ports on the TV, but I'd have to hope that the TV has optical out, which not all do.

Thanks for the recommendations, though. The Polk products like very promising, and they seem highly rated for the category...
