I just moved into a new home where the surround speaker wire (16 gauge) had already been installed in the wall. The speaker run is about 30 feet for 1 side and 17 feet for the other. I just noticed in a Revel speaker brochure online that they do not recommend using a 16 gauge wire for runs longer than 9 feet. According to their chart, I should use either a 10 or 11 gauge wire. Any truth to this? Will it effect sound to that great a degree (bass/soundstage)? I have a Bryston st amp.
