You should also know that to get repairs on a piece of Parasound gear you have to take it too one of their local electronic repair shops. In Houston, the repair shop is an old tv repair shop. I left an amp there for six weeks after which they finally informed me that they still had not obtained the parts. I gave up on the Parasound and would not buy another product from them. Make sure you check who does repair work for the brands you are interested in. I will only buy from manufacturers who handle repairs themselves.
