Summary: I have been using Yamaha receivers for the last 5 years, starting with RX-V 1500. RX-V series are superior in sound quality to the other receivers by yamaha. My Yamaha 1500 and 1600 did not allow volume monitoring on Samsung 40 inch LCD TV. Sound quality of 3900 is by far the best i have listened to. One set back is the receiver gets warm and this was the case with RX-v 1600. I installed a small electric fan at the rear end of the receiver and it helps.
Summary: I have long been a Denon Fan and when it came time to replace my Harmon-Kardon receiver I had every intention of picking up a Denon as I had been pleased with other Denon products in the past. When I did a head to head comparison between the V3900 and the Denon 3808, I just prefered the sound of the Yamaha better. I had already made up my mind and wanted to like the Denon more, but the Yamaha sound just had more presence. I have had the V3900 for 3 months now.
Summary: Other people have gone into all the great details on this receiver. Overall I am very happy with it and have no problems. When I finally decided to upgrade, I knew I wanted to go with a networked receiver that also had HD radio and XM/Sirius and at least 4 HDMI inputs for all my equipment. I figure this should stay current for many years to come. To meet my needs, it meant spending $1,600.
Summary: I'll keep this review short, as the other reviewers have covered a lot of ground here. However, since I upgraded from the Yamaha 1800 receiver to this unit, some folks might find my thoughts interesting. High points: - Overall sound is excellent, as well as very flexible. A slight upgrade from the 1800 - Video processing is top notch. I actually use the HDMI -> HDMI up-conversion, as for non-1080p sources I believe this improves the overall picture quality.
Summary: I purchased this unit a week after it went on sale. I had been investigating the device for some time prior to the actual release. I used this to replace a Yamahe DSP-A1 purchased about 10 years ago. I wanted to simplify my cabling by switching to an HDMI capable receiver. The availability of 4 HDMI inputs was a big selling point for me.
Excerpt: Weihnachten 2009 war es so weit. Mein altgedienter Surround-Referenzverstärker Yamaha DSP-A1 (ehem. UVP 2300 Euro) musste Platz für ein neues Gerät machen, weil der alte Bolide keinen Dekoder für die neuen HD-Audioformate (Dolby Digital TrueHD, DTS-HD High Resolution Audio und DTS-HD Master Audio), keine Anschlussmöglichkeiten für ein 7.1 Lautsprechersystem und keine HDMI-Anschlussmöglichkeiten bot.
Pros: Implementierung aller modernen Tonformate, fantastische DSP - Programme, super DSD - Wiedergabe
Cons: Preis, nicht ausreichende Netzwerkfunktionen, unterer Teil der Fernbedienung unbeleuchtet
