Summary: My quest for a better AVR will continue. I almost changed my AVR every 2 years. I was an old DENON fan until 3 years ago. Used its high end CD players, integrated amplifiers, etc. After my first Yamaha AV I turned back to Denon with 3806 which was an excellent one. Then I upgraded to 3310 for 2 months (DSP chip failure) changed it with 4310 which worked fine for a year then failed with its network card. Sold it and switched to Onkyo with TXNR 809 2.5 years ago.
Pros: New Audissey of course.
Cons: Remote is quite limited. Still looking for other things to complain
Summary: I was wondering if denon still made top quality recievers and yes they do. The sound is amazing it runs a little warm but I bought a fan which sucks the hot air out of the top of receiver problem solved. Dts neo x sounds amazing but you can not select it if theres a digital source like dts hd or dolby hd ect.
Summary: 28.4.2014 It has been 3 months and I'm using receiver every day. It does excellent job, no problems at all, still learning all what this unit can do!!!! 1/1/2014 I start to shop for A/V receiver month ago. I contacted all brands Yamaha, Onkyo, Denon. After chatting, emailing and warranty and price compares I decide for Denon.I replaced my 10 years old Denon 3803 witch was my first receiver, did excellent job and I have zero problems with it.Got this new X4000.
Summary: Sounds good, powerful and basically every feature we could ask for. I use iRule to control it from my iphone/ipad, which works great over your home network. The only thing that I don't like is that when you use airplay - it completely takes over everything when airplay connects. So - if you are watching TV in the mainzone, and Pandora in the second zone, and then connect airplay, both zones will start blaring whatever is playing on your ipad, and do so at whatever volume...
Summary: After taking a lot of time reviewing many AV receivers, I decided to get this one and I'm glad I did. I have set it up with the microFidelty Mini Amplifier on the front high speakers connected to the pre-amps so that I get a full 9.2 surround sound capability. My new home theater is rocking with the sound this receiver produces.
Summary: This is the 5th receiver I've purchased in the last 20 years. My last receiver started to fail after only 3-4 years of moderate use. It would drop sound for a few seconds periodically and then recover. I had typically bought mid-range receivers from a well known compering brand. After researching the AVS forums, I discovered the problems with my last receiver were common and the overall quality of the brand I had been loyal to had plummeted.
