Like its more expensive sibling, Denon's AVR-991 features 7 discrete power amp circuits, with each channel is rated at 125 watts (8 ohms, 20Hz to 20 kHz, .05% THD), a 20-watt per channel gain over the 2311ci or 891, and a .03% reduction in Total Harmonic Distortion.
The AVR-3311ci has 6 HDMI 1.4a inputs which provides 3D pass-through for Blu-ray and Broadcast content, and also supports Audio Return Channel. There are also two RGB component inputs (capable of up to 1080i), two S-Video inputs, four RCA composite inputs (including the front), two coaxial digital inputs, two optical digital inputs and seven stereo RCA inputs (including the front). iPod owners can connect via the USB input or they can also purchase an optional iPod docking station such as the ASD-11R for around a hundred bucks.
Handling all the video from the many analog and digital inputs of inputs is Anchor Bay's fourth-generation video engine, ABT-2015 10-bit Video Processor / Scaler. The ABT2015 upconverts and deinterlaces all signals to a native 1080p (24fps or 60fps) resolution with mutli-cadence detection.
In the category of surround sound processing, AVR-991 decodes all the modern codecs with ease. On the Dolby side of the fence, there is TrueHD, Digital Plus, Pro Logic IIz, and IIx. DTS capabilities include HD Master Audio, ES Discrete 6.1, Matrix 6.1, Neo:6, and 96/24. It also has Audyssey's DSX surround processor which derives both front height and front width channels. On top of the surround processing, Denon includes Audessey's MultEQ XT Auto Calibration along with Dynamic Volume and Dynamic EQ. Using Denon's Power Amp Assign function, owners can choose to use 2 of the amp channels for surround sound back channels or front height speakers (using Pro Logic IIz), or they can be assigned for stereo second zone mutli-room use.
The AVR-991 is also a Network Ready receiver and will connect to most wired broadband home networks (via the RJ-45 LAN connection). Not only can users connect directly to internet radio via Pandora or subscription music services such as Rhapsody and Napster, but they can also connect to any DLNA-compatible multi-media home PC to share music and photos. Photo viewing via photo sharing websites such as Flickr is also available.
The Denon AVR-991 is a very capable mid-level entry into the world of 7.2 channel surround sound. Missing are pricier higher end features on the 3311ci as well as THX certification, 9 or more channels of amplification, and WiFi connectivity. The 991 is available online and in local retailers for around $999.00.
