Best Surround Sound System Installation in San Francisco CA

Cham was a pleasure to work with!    We had our house hardwired for cat6, alarm, multiple point access points, new TV's, Sonos, IP based doorbell, smart lighting and savant system.   Cham's guys were professional, clean, and detailed oriented.  I've worked with a lot of other folks before and have never met a better set of folks to work with.   I would recommend them in a heartbeat.
