One of the things we are always amazed at is the constant arrival of new technology. We just come to the shop 6 days a week and the front door opens on a regular basis with something new. Home Theatre was a big one, but Wireless Audio is right up there. The year was 2006 and multi-room sound was really popular if you were building a new home and happy to run tons of wire. Well the wires are almost gone and the brands offer a wide range of products.
