Advanced Audio Video.
I have used Advanced Audio Video four times over the last five years and have always been extremely happy.
Mark Proper is extremely knowledgeable about all things audio/video and is great to work with. I have used Mark for wiring (indoor and outdoor), installation (full home theater and outdoor audio) and purchased equipment directly through him over the years. He is very honest with his advice, even down-selling equipment if you are looking at items that are too advanced for the intended use (unlike big box retailers who try to sell you the latest technology for everything).
I would highly recommend using Mark, and have done so to friends and colleagues already.
