Until recently, you weren’t likely to find many $2k + receivers out on the market. Perhaps this is because, in the minds of most consumers (and many A/V enthusiasts as well), that $2k price point indicates that you just flew past the mile marker for the law of diminishing returns on the A/V super highway. At some point we ought to consider the option of separate components and their premium performance as an alternative to a pricey receiver. That is, unless the receiver in question is a total knock-out.

What you get in a receiver priced at around $2 grand, in the case of the Denon AVR-4311CI, is just about A/V feature you’ve ever heard of and then some. We wonder, though, if the advanced functionality and sound of this high-end A/V receiver is so mind-blowingly awesome that it’s worth the lofty price tag. We took our time digging in to the 4311CI and we think we have the answer.

Out of the Box

Denon’s AVR-4311CI comes packed along with a heavy gauge power cord, radio antenna, Audyssey microphone, a main zone remote, a zone two remote, batteries and a manual. The 4311CI measures 6.7” x 17.1” x 16.6” (h,w,d) and weighs a respectable 38.2 pounds. As we lifted the receiver from its box, we were surprised to feel that its 38 pound heft was not concentrated entirely in the power supply section – rather it was evenly distributed throughout the chassis. The black facade is adorned with two large rotary dials, 7 small control buttons, a smoked display window and a flip-down panel. Denon softens the look of the receiver by adding some curves to the trim of the display window and implementing a sunken relief on the top and bottom edges of the chassis. Denon also bucks the blue LED trend by backlighting its power switch with a soft green LED.

Features

Denon’s 140 watt per channel AVR-4311CI is so jam-packed with features and functionality that we just can’t list them all here, but we will highlight some of the more advanced and unique aspects for your techno-geeking pleasure.

The 4311CI is technically a 9.2 receiver as it has 9 discreet amplifier circuits, and it offers the option to assign two stereo channels as you wish. These assignable outputs can be configured to perform several different surround and multi-zone roles. For instance, it is capable of up to 11.2 channels of surround sound, including surround back, front height and front width channels, which promise to add more dimension to surround sound tracks, but you’ll need an external amplifier for one of those pairs of speakers. If multi-zone audio is your thing, you can run a 5.2 theater and two separate zones of audio. If you would prefer to bi-amp your front speakers, you can still run surround backs, front height or front width channels. The potential combinations are dizzying.

If multi-room control is what is needed, the 4311CI offers flexibility in serving the second and third zones. It sports two HDMI outputs, both with audio return channel, and can decode digital audio signals for amplification in the other zones. No more unnecessary analog cables. Users can even configure crossovers, bass, treble and default volume settings for both zones 2 and 3.

The 4311CI is equipped with Audyssey’s top of the line MultEQ XT32, which applies filters to each speaker in the system, including the subwoofer(s), based on readings it takes from up to 8 positions in a room. MultEQ XT32 can be easily upgraded to PRO level which offers up to 32 different measurement positions. For those who prefer a manual calibration, the 4311CI offers all the tweaky adjustments one could ask for including 10 different crossover points for each speaker, a fully manual EQ and a clever system for balancing two separate subwoofer output levels.

The 4311CI is a very network friendly receiver. Its front and rear USB inputs will accommodate flash drives, hard drives and a direct iPod interface including simple on-screen navigation. It is DLNA certified, so it will stream audio and pictures from any networked computer that is sharing content. There is access to Rhapsody, Pandora, Napster, Flickr and internet radio. As if all of that content weren’t enough the 4311CI is one of a handful of Denon receivers that can be upgraded to use Apple’s AirPlay. For $49.95, the 4311CI can be upgraded with the AirPlay option which allows iTunes and most other iDevices to stream audio to the receiver for playback in any zone.

Denon didn’t seek THX certification for this model so it doesn’t offer any THX post-processing but is, of course, capable of decoding all of the latest surround codecs and offers plenty of its own post-processing options too, including a proprietary Cinema EQ processor that tames some of the brightness commonly associated with movie mixes. It even supports SACD and HDCD playback via HDMI.

The 4311CI packs in plenty more but we’re running out of space here. So, if you need to know if the 4311CI offers a phono input, headphone output (it offers both) or any other specifc feature, feel free to browse Denon’s extensive product description here.

Performance

To evaluate the AVR-4311CI, we connected an LG BD-370 Blu-Ray player, an Xbox 360, Pioneer turntable with Ortofon OM5E cartridge, an iPhone 3G, a Kingston flash drive loaded with various quality music files and an Ethernet cable for network and internet access. For speakers, we used systems from Aperion Audio and Boston Acoustics.

Since the Denon 4311CI is so capable and feature rich, setting it up is an unavoidably complex proposition. To Denon’s credit, much has been done to present the overwhelming and sometimes intimidating settings menu in an intelligible and navigable manner. The 4311CI uses a scrolling icon-based menu that gives you a preview of what’s available in each sub menu before you actually enter it. There’s no trail of breadcrumbs to keep you oriented within the menu so users may want to keep the user manual nearby to keep from getting lost or sidetracked.

Thankfully, our review sample was upgraded with the Apple AirPlay feature prior to being shipped to us. Still, we checked up on the upgrade process and it was simple enough. A quick trip to the Denon website revealed complete instructions on the process, which requires the receiver to be connected to the internet. Armed with some key pieces of info from the receiver, the user purchases the upgrade at Denon’s website, then ques the receiver to upgrade its self.

We chose to bi-amplify our front left and right speakers and add in rear surrounds for a 7.2 speaker arrangement. Over the course of our audition we ran Audyssey’s set-up routine seven different times using two specific measurement locations. We ran it twice on each speaker system and then once again to test the differences in results when we allowed Audyssey four measurement positions instead of just two. In every case, the result we got from Audyssey varied. The measurements for speaker level remained fairly constant, but the distance settings and EQ settings were all over the map. Sometimes the results were pretty good, other times not so much. The bass response, however, was consistently improved. During the audition we toggled Audyssey on and off along with both the dynamic EQ and dynamic volume settings and generally preferred the sound we got with all of the above turned off.

After some lengthy setup sessions, we finally got to test the functionality and sound of the 4311CI. We first dug in to the unit’s Net/USB section, which allowed us to play back content from internet radio, iPhone, USB flash drive, Pandora and everything on our networked PC. We really enjoyed the interface. Having all of the networked music options listed under one menu made navigating our choices easy and fun. We appreciated seeing the bitrate information for the files we were playing back and noted along the way that the 4311CI was able to handle even the highest bitrate files from our computer – a feat we haven’t seen pulled off by any other network receiver yet. The USB iPod interface was one of the best we’ve seen, though we still longed for something as simple as shuffle and repeat control.

AirPlay was a lot of fun to play with. iTunes recognized the Denon immediately and began playing back tracks just seconds later. Though our iPhone 3G doesn’t appear to support AirPlay, we were able to control iTunes with our phone and make playlist changes on the fly. If you aren’t familiar with AirPlay yet, then you need to know that all of the control lay with your computer or iDevice (iPhone, iPad or iPod touch)-you can even control the receiver’s volume remotely. What you can’t do is control your music selection from the receiver. With AirPlay, communication is a one way street.

The sound quality from the network content was uniformly good and consistent with the quality of the music file. With Pandora, everything comes across at 128k and sounded like your average iTunes file. Higher quality files sounded significantly better with the highest quality files rivaling CD quality. Low bitrate internet radio stations still sounded poor, but we found that some of the stations were broadcasting an AAC format that sounded really good. We didn’t find Denon’s “restorer” feature to be all that useful. It processes low bitrate files and aims to improve their fidelity. As has been our experience with similar processors from other manufacturers, it acted like a loudness button with three different tiers of intensity, each one progressively louder than the one before and with hotter highs and slightly boosted bass.

After days of setting up, measurements, tests and general poking about with the AVR-4311CI, we finally got to some meat and potatoes listening. We pulled out our arsenal of two-channel and multi-channel listening material including some vinyl, SACD and DVD-Audio as well as a handful of blockbuster movies on both Blu-Ray and DVD with surround tracks known to challenge the most powerful of receivers. For all the bells and whistles, this Denon receiver still needs to shine at audio reproduction.

The AVR-4311CI sounded great. Those who have enjoyed the Denon sound in the past will be thrilled with the articulate, nimble sound of this receiver. During our 2-channel listening, we appreciated the unmistakably clean Denon sound with its warm, slightly laid back midrange and sparkling top end. Bass was very well asserted and under tight control which helped to round out a very classy sound with just enough detail to keep you going back to all of your favorite recordings for another listen.

Multi-channel music was equally impressive. There was no discernible bleed between channels, but the soundstage they painted was well integrated. Instruments had distinct locations within the room and in places where there were no speakers, thus supporting the sonic hologram that the recording’s mix aims to create. Once again, the 4311CI’s ample headroom helped deliver poignant and highly dynamic musical moments at hearty volumes without showing signs of strain.

Movie soundtracks were a treat. The 4311CI’s hearty power supply went to work to keep all channels driven with authority. At one point, we had full size, floor-standing speakers in every speaker position and the 4311CI handled the load impressively well. Highly explosive scenes being pushed through 5 power-hungry speakers with the volume cranked up will make any receiver wince, but the 4311CI hung in there and drove the system well without breaking a sweat. We certainly had more power than our medium sized room could handle so we feel very confident recommending the 4311CI for large rooms and/or open floor plans.

Conclusion

The Denon AVR-4311CI crams in tons of features and functionality, yet still manages to save enough room for a beefy power supply, high quality DACs and muscular amplifiers. The result is a feature rich, network capable receiver with enough guts to power big systems in big rooms. While it doesn’t achieve the sonic majesty you are likely to experience with a separate pre-amp and multi-channel amplifier, it gets pretty close. Plus, you aren’t likely to find this many bells and whistles in any pre-amp short of $2k. Just be ready to invest some serious time (and patience) into the setup process if you want to forego hiring a professional installer.

All things considered, the 4311CI does a decent job of earning its asking price. It sort of creates its own category because such a rich feature set doesn’t really exist at this price point. For those who want a future proof receiver with room to meet expanding needs, we encourage you to give the 4311CI a close look.
