We first used KS Audio Video about 4 years ago when we needed to change the way DTV was installed at our house and it was way too complicated for DTV to do themselves. We had been told what we wanted to do was not possible becuase of the way our house was originally wired, but KS was able to make it function the way we wanted without tearing out walls or rewiring everything. Since then we have used them for two big projects and several smaller ones. One of the applications we use the most is having four inputs (DTV, DVR, Bluray, Apple TV) be controlled by one system (Control 4) that we can access via remote, computer, ipad, etc. This inputs can be watched on any or all of 4 outputs and the sound and visual is controlled together. Their technical knowledge is top notch, and their customer service is very strong. If we have a problem, I know they will respond in a timely manner and have someone out here if necessary to find a solution. I trust their techicians as well and they know our family. Little things like laying out a blanket to protect the carpet with parts on the floor, making sure our dog does not disappear with wires, etc, go a long ways into building a good customer relationship.We have recommended them to several family members who have also been happy with their work and customer service. They can do basic and specialty work. At my mother-in-laws, they installed a TV that looks like a mirror when not in use and hid the speakers in the wall. At our conference center, they installed a large visual system supported by speakers hanging from the ceiling with a controller that can use multiple inputs (computer, ipod, ipad, etc).It's refreshing to find a business that meets or surpasses expectations on technical knowledge, getting the job done correctly, and great customer service.
