Amazon.com Product Description
The AVR-688 surround sound receiver is network ready and can integrate into a home networked system when used with the optional ASD-3W/3N iPod docks, allowing more sources for playback then ever before. HDMI 1.3a video switching has been employed for today's demanding HD sources, providing rich color quality for 1080p signals. Digital audio is distributed by either optical or coaxial connections to high speed surround processing circuits for premium quality Dolby Digital and DTS Digital decoding. Seven high-current style amplifiers are used in the AVR-688 to deliver clean, clear performance for unmatched sound quality from your DVD or set top box digital devices. Analog video up-conversion makes switching various types of analog video signals easy, as duplicate wiring can be eliminated and signals channeled into one single component video output. Audio Delay is provided to allow for exact matching of audio and video signals when signal delays occur from some audio/video sources. Our newly styled pre-programmed remote control provides ease of use for the newcomer, or enhanced use for the seasoned user.

customer review :

My 2005 Yamaha 650 series was very good to me until my dog chewed one of the speakers wires and shorted out the receiver, so I decided to try the new Onkyo TX-SR605 model everyone was raving about besides the overheating problem with Onkyo, everything I heard about the receiver was good. Which I agreed until I tried the Denon. I did all the automatic speaker calibration which worked very well. The sound was ok but not very impressed so I tried tweaking with the sound but did not get much better. Remember, I was comparing this unit to my Yamaha. Then I decided to look to see what else what out there around the same price and the Yamaha and Onkyo. I found the Denon AVR-688, so I tried that out since I knew Denon was pretty reputable. Both places had a 30 day return policy so I new I had 3 1/2 weeks on left on the Onkyo to do the comparison. After the lengthy set up with the Denon (took me 4 times longer to set up the Denon than the Onkyo), which is not as hard as people say as long as you go step by step through the instruction. I decided to play some music and all I can say is this thing sounds 20% better than my two year old Yamaha and 40% better than the Onkyo. The Onkyo was very good for the money but the sound did not have the depth of the Denon. Listening to a TV program, the center speaker sounds so much more life like. The Onkyo had a very thin sound compared to the Denon. It was almost like teh Onkyo was playing through curtains. This is playing on a $400 center speaker. I wish I could put a picture on here of me with both receivers just to prove that I did the test. This is not just my opinion but even my wife, who could care less of how it sounds, said she could tell a difference. I had them both out side by side so I could quickly plug up one to compare. I also use banana plugs to for the speaker connectors to make the swap even faster. I will be returning the Onkyo this weekend. I do have not have a vested interest in this article but the difference in sound was worth writing.
