I went to Sound By Design because I wanted to improve my stereo system. They helped rewire and hook up some audio/video equipment. The guys did a really great job. They hooked up a high end audio video receiver, 75" wall mounted television screen, blue ray disc player and Yamaha receiver. The sound system consisted of two towers, one center, one sub woofer, and 4 book shelf speakers. I am very happy with the installation. The whole system is awesome. They did the whole thing quickly and efficiently with no problems. They cleaned up everything when they were finished. I would absolutely recommend them to friends and I will call them again when I need to upgrade or if I have any problems.
