Very Impressive AVR
I've owned Pioneer and Emotiva AVR's in the past and although they are both high quality sounding systems, in my opinion this Denon 4100w is the best sounding system I have heard to date. I'm sure part of the reason is due to the fact that Denon uses Audyssey's room calibration. I've read a lot of good reviews on Audyssey and now that I've experienced it I'm a believer. After running Audyssey the only thing I had to manually change was the front speakers from large to small and the crossover setting. The mix is rich, the subwoofers are perfectly blended and the surround sound has much more detail and dimension. No matter what your circumstances or tastes may be, there are plenty of audio options to satisfy and they all do an excellent job.
Another one of the reasons I purchased this unit was due to its available speaker configurations in Dolby Atmos mode. It can be set up as 5.1.2 (2 ceiling speakers) out of the box, and by adding a 2 channel external amp it can be expanded to 7.1.2 or 5.1.4. I decided to configure a 5.1.4 setup and this AVR was the best bang for the buck in that department. True, it kind of sucks to have to buy another amp, but I can pick up an AudioSource 100 for $125, and that still leaves this unit the best price at this time.
Due to the fact that there is no available media yet, I haven`t had a chance to check out Dolby Atmos. As soon as a movie is available on blu-ray with Atmos I will update. But I expect it will sound pretty dam sweet!
Update: My wife won't speak to me now, and I don't blame her. I ended up returning the 4100, spend another $600 and bought the 5200. My bad! I'm sorry Hun! I know I should have talked this over with you first, but you would have said no, and I REALLY, REALLY wanted this. Have no fear, folks. she'll be fine when I fire up Atmos with 7.2.4.
I've had a 7.1 system for several years and I was having a hard time down sizing to 5.1 when using Atmos (which would actually be 5.1.4). Sure, the 4100 is also a 7.1 system, but not in Dolby Atmos. And sure, I could switch speaker configurations when not using Atmos, but if I wanted to use Audyssey (and I love what Audyssey does for the sound) I would have to run room calibration each time I wanted to reconfigure my speaker setup, and that would be a pain in the a**! So it just made more sense to me to go with the 5200 and have the best of both worlds. I love you, Babe! :o)
Update:(10/7/2014) Great news... my wife's speaking to me again. We finally watched our first dolby atmos movie (on the 5200) and we were both impressed. The sound field was much more immersive than either one of us expected. Looking forward to more atmos releases.
Just bought the new X4100W couple of weeks ago based on its feature set and Denon Track Record. I have to say that this AVR completely fulfilled my expectations.
Coming from an Onkyo that even had the HDMI board failure this AVR is a completely deferent experience, I paired it with some Polk speakers (RTIA7, CSIA6, RTIA1 and DSW550) and i have to say that the X4100W has no problem to drive them even at full power.
WiFi and bluetooth are killer features and the work excellent. I have became a lover of Airplay from my IPad which right now is mainly my music source now.
On the video side I have connected it to a Samsung UN65HU9000 4K Screen and it has been working flawlessly, even with the HDMI-ARC (Audio Return Channel) to send audio back from the TV to the Receiver when using the Samsung APPS like Netflix and Skype.
I have found a small issue in the operation together with the Samsung UN65HU9000 and the ARC, however the problem is not of the Denon Receiver but the Samsung TV. The problem is that in order to have ARC enabled, you have to enable HDMI-CEC and Anynet on the TV. When the TV comes up always switchs the AVR to the TV audio instead or leaving the A/V though the source selected in the AVR.
As long as I get more time with this AVR i will be updating this review
WOW! This is a WONDERFUL RECEIVER! You won't REGRET IT!
This is a wonderful, wonderful, wonderful, wonderful system. I used to have an old Denon receiver and got this receiver two weeks ago with Definitive Speakers, WOW! I can finallly enjoy music the way one is supposed to hear it! I have no complaints. At first I could not connect any RCA input in the back, but then when I called Denon they walked me through the setup for each RCA inputs and everything worked well. So far, this is a fantastic system. I purchased this based on other customer ratings and I am glad I did because I am very very happy with this purchase. Thank you so much for all the details of the other feedback providers. Yes, I would definitely recommend this system to anyone. For me the price was a little stiff, but I guess for this kind of system and because it is a new model the price is a little high, but the quality is excellent. Thanks to all of you who already wrote detailed feedback on this, I am really happy with this receiver. FD
The best AVR that i ever enjoy. Elegant, beutiful and Powerful.
