Barry O'Brien's Performance Audio of San Francisco is what they call a hybrid audio-video store meaning that they are transitioning to custom audio video installation from its traditional roots of audiophile and two channel retail sales. Performance Audio of San Francisco website, to be polite, is poor lacking any meaningful installation shots which will be a warning sign for many big dollar consumers, architects and builders.

Performance Audio of San Francisco sells AudioQuest, Crestron, Anthony Gallo Acoustics, Middle Atlantic Racks, Panamax, Runco, Sonance, Triad, Audio Research Definitive Technology, Kalidescape, M&K (didn't they LONG go out of business?), Paradigm, Sanus, Sony, B&K, Denon, Lexicon, Mitsubishi, Pioneer Elite, Speakercraft, Vandersteen, Lutron, Niles, Revel and Stewart Filmscreen.
