Summary: There are plenty of reviews here that describe all the features of this receiver, so I will not go into that. I upgraded from a DSP-A3090. Well, shortly after the warranty on the 3900 expired, the power relays started shutting the unit off randomly. Now, I can barely get it to turn on.
Summary: I have bought at least 2 Yamaha Receivers and have never had a problem until now. I bought the Yamaha RX-3900BL 7.1 receiver because of all the features and because of Yamaha reliability. When I got the receiver in October 2008, I noticed that the HDMI port for Cable/Sat did not transmit audio.
Summary: I replaced the Yamaha RX-V3800 with the RX-V3900 so I could get on-screen graphics over HDMI, and because I wanted HD Radio. I did the latest (as of 12/4/2008) firmware update (1.04, I believe).
