We used Digital Lifestyles to both setup a home theater for us in our basement as well as link all TV's and built in speakers to a single rack of hardware (cable boxes, xbox, apple TV etc) so that from anywhere in the house you can listen to music or watch TV on any TV from any of the input options. We also had them purchase the home theater chairs for us.
overall - very happy with the outcome. While there have been bumps in the road (we have had to have a few pieces of HW replaced), they are very fast to respond to questions and issues, and have dealt with every item we have brought up to them post-installation. The sales staff (Scott mostly) that we worked with were very thorough in making sure we were getting what we wanted, including recommendations that helped to bring costs down or streamline in some cases, and the installation/support guys (Brian and Kris) have all been very friendly, relatively punctual or at least keep in touch when prior jobs have them running late, and are willing to come back whenever necessary to make sure that things are running smoothly.
for the few frustrations we have had when things have stopped working or needed a wire replaced, and the troubleshooting they have had to do for issues that are difficult to replicate, they have been wonderful to work with, and we highly recommend if you have any plans on building in an integrated entertainment system. While these systems will cost you, having a company that really backs up their work is worth it.
