Got mine in Amazon on July, '06.All was fine until a few weeks ago, when the HDMI-out port died. With my components all HDMI-based, losing that port was tantamount to losing the product.I replaced the receiver with a Denon, and all clicked again. Working now with Yamaha to get their receiver fixed - will report here how that went.
