This receiver is much better than similar products I've owned from Sony ES, Pioneer Elite, etc. I think the sound is better than some of the most famous audiophile gear, such as a hybrid tube/solid Counterpoint gear I tested it against. I'm fairly demanding of audio gear (my reference rig was a single-ended triode setup with no preamp or anything else to muddy the sound, to give you an idea). This isn't quite the ultimate audiophile rig, but it comes surprisingly close and it does have a really exceptional combination of quality, features, and convenience. I'm very happy with the sound quality. The manual could be better, but it is usable. The ability to configure the receiver to drive another room was a key feature for me; my better half wanted to be able to hear music or TV in the study, and this does it nicely. The audio quality from the tuner is surprisingly good; it makes me think there's far less market opportunity for the new HD tuners than I'd thought previously, but I'll keep an open mind! Still, with a strong signal the FM quality is quite surprisingly good. One drawback: there is noticable delay and a flicker in the video switching as it tries to lock onto a video signal when I change channels in my vcr tuner, and I haven't noticed it doing anything (positive or otherwise) for the video signal, but I'm just using composite so it's not a fair test. I like the extensive back panel connectivity, too; it enables a lot of flexibility in how one uses this product. I also found the EZ set self equalization easy to use. At first I wasn't impressed with the auto equalization, but after a lot more testing and experimentation it can really make a significant improvement. It's really pretty impressive, and it succeeds in compensating for a lot of speaker placement challenges and room accoustics issues that can be very hard (and very expensive & inconvenient) to address otherwise. The end result is a very significant improvement in system performance, but it took some "fiddling" with the settings. Overall, I have to say I'm extremely happy with this item, and I honestly don't know of a better integrated receiver solution.

Features - Harman Kardon AVR 635 7.1 Channel Surround Sound Audio/Video Receiver
Overviews - Harman Kardon AVR 635 7.1 Channel Surround Sound Audio/Video Receiver
Power meets power. The AVR635 combines the sonic power of a high-current, ultrawide-bandwidth amplifier with the computer power of Texas Instruments' most advanced audio DSP to deliver unparalleled performance. Thanks to Harman Kardon's advanced EzSet/EQ functionality, the AVR635 not only automates speaker, output and delay settings; it corrects for room acoustics with a parametric equalizer. Add video conversion circuits that output all video sources via component connections with on screen graphic, and you have the power to tame any system and deliver powerful performance.
Specifications - Harman Kardon AVR 635 7.1 Channel Surround Sound Audio/Video Receiver
Surround sound features include Dolby Virtual Speaker, Dolby Headphone processing, and Dolby Pro Logic IIx processing (which provides an expansive, full-range 7.1-channel program from any stereo or 5.1-channel source). The receiver handles all other popular formats (including Dolby Digital EX and Dolby Digital 5.1), all standard DTS modes (including 6.1 DTS-ES Discrete, DTS-ES Matrix, DTS Neo:6, Cinema 6.1/5.1, and Music 6.1/5.1), and even the latest DTS 96/24 high-resolution audio technology. In addition, the AVR 635 provides HDCD (High-Definition Compatible Digital) processing to deliver the best possible CD playback quality from HDCD-encoded discs. You also get Harman's proprietary Logic 7 audio for enhanced multichannel reproduction from both matrix-encoded and 2-channel recordings. The latest implementation of Logic 7 provides improved post-processing for the rear surround channels. The receiver's many audio and video connections include three wide-bandwidth, assignable HDTV-compatible component-video inputs. The AVR 635 also features multiroom/multisource operation with independent, simultaneous playback of two program sources, assignable back surround amplifier channels, A-BUS connectivity, and a Zone II remote. The A-BUS Ready system simplifies multiroom connectivity without external amplifiers. It uses a standard Cat5/Ethernet cable to connect the receiver's rear panel in one room to a Harman Kardon AB 1 A-BUS-compatible amplifier/control module in a separate room. Along with its extensive video connectivity, the receiver offers a array of digital and analog audio connections, including multiple coaxial and optical digital audio inputs and outputs. It sports both analog and digital front-panel inputs, 6-/8-channel direct audio inputs, and 7.1-channel preamp outputs to accommodate a DVD-Video, DVD-Audio, SACD, or universal player. The AVR 635 is also among the first receivers to include EzSet/EQ, which provides automated system calibration and room equalization, which greatly simplifies installation as it improves system performance by tailoring the output of the receiver to your speakers, compensating for the effects of room acoustics. The receiver's quadruple-crossover bass-management system lets you choose from six different crossover frequencies for the front L/R, center, surround L/R, and surround back L/R speakers. Most receivers and DVD players have far more limited crossover filtering or none at all. Moreover, you can set different speaker-size configurations for different AVR 635 input sources according to your needs. You get a high-quality FM/AM tuner with 30 station presets and a Listener Preference System that lets you specify a surround mode according to the program source. You can also set speaker-channel levels for each program source and DSP format (for example, the subwoofer level can be set differently for multichannel movie viewing and 2-channel CD music listening). What's in the Box
Amazon.com Product Description Harman Kardon's AVR 635 7.1-channel audio/video surround receiver includes the company's latest features and technologies on top of near-universal surround-format compatibility. Internally, the receiver is engineered for extraordinary sonic performance, featuring a discrete-output amplifier section that delivers seven channels of high-current (+/- 50 Amps), ultrawide-bandwidth amplification--7 x 75 watts into 8 ohms, 20 to 20,000 Hz with less than 0.07 percent THD--in addition to state-of-the-art 192 kHz/24-bit audio digital-to-analog converters and a high-power Texas Instruments 32-bit DSP processor.
The AVR 635's wealth of cutting-edge technologies also includes quadruple-crossover bass management, automatic digital input polling, video cross-conversion (which converts all composite- and S-video sources to high-resolution component-video), bidirectional RS-232 connectivity with software and firmware upgradeability, A/V sync delay, and a slot-mounted tuner that may be upgraded at a future date to accommodate HD Radio.
