I have this fairly expensive Marantz SR6006 sitting in a closet. It had an HDMI handshake problem from day one no matter what cable or source I used. It died at age three just after the warranty expired. When I said it died of congestive heart failure I wasn't far off as the darn thing was too complicated for it's on good. I replaced it with an entry level Yamaha RX-V377 which works fine except when it mysteriously changes inputs on it's own. Sound wise they are/were about the same. I learned my lesson regarding expensive AVR's.
