Summary: Bought this only because it had abus control, moved into new house that was quoted for it. The sound on hk is supposed to be top notch but this one isn't. The Yamaha I had set up before sounded much better and didn't have problems playing all 4 of my speakers.
Summary: the Receiver works very well as long as long as your speakers don;t start to make a chirping sound and it will move from one speaker to another, I called Tech support at Harman Kardon and the man helping, could not understand me very well, they are based out off the Philippians, so his conclusion was the chirping was because the Receiver was going into protection Mode,, I told him why it was at 30-40% volume it should not do this,,,,so I got NO HELP from them at all,,,,...
Summary: Thought I was buying quality, Audio and Video problem 2 years into purchase. Finnaly the video quite. Took it too a HK recognized service centre. I was told the HDMI board was gone and replacement parts not available. Sounds like others have had the same problems with same results.
Summary: My top line is- dont buy, it will have issues but the customer service is just NOT worth it. !! Its way more hassle than its worth, their customer service needs a major overhaul.... My AVR3600 worked well for about 10 months, literally no issues, and its a great machine when its working. Then it started to go awry. Sound would shift into different modes, as I had only 2 speakers rigged, this meant that some of the sounds were not coming through.
Summary: While unavailable for purchase at the time of writing (2013/27/07) this receiver deserves a review. The previous comments detailing the various snafus with this receiver are correct but none of it has been a deal-breaker. Much to the testimony of the build quality this receiver lived through a severe power short at my household causing the power to be highly irregular. The protective circuitry did it's task more than once.
If you are looking for a great surround sound receiver,ths is it!

Summary: I have owned surround sound receivers ever since they first came out and this one is the best one I have ever owned! It comes with a microphone that you put in the listening spot, then it sends out frequencies to all the speakers to calculate how to calibrate the surround channels! No more guessing how to set the delay values! The remote has a 'glowing' button that you can push to light the whole thing up so you can see where you want to go on it.
Summary: I bought this for my brother and sister in law as a welcome gift to their new home. They love the sounds and the power it delivers. The only issue they had was that it didn't offer pass through so they couldnt have the TV on using the TV's speakers while the cable box was plugged into the receiver. This wasn't good for them at night time but he found a way around that with an hdmi splitter.
