They did a retro fit to my current set up that needed a major overhaul and new remote set up. I had another company look at it and they wanted over 5000.00 just to upgrade and rework the remote system. Audio video synergy did all that for under a thousand and I like the new remote setup much better than the older more high tech(?) remote. The changes to my set up, such as a new Projection and sound, that they recommended were sound, reasonable, and within my price range. They were presented with several problems once they started as my set up is complicated, and they found good answers to those challenges and the cost did not increase much once they were started. While the end invoice was slightly higher, only due to the unforeseen trouble with a Sub-woofer is was less then a 5 increase...the first time it was set up by another company the over run was about 35. Very pleased over all and would certainly use them again and recommend them to all.
