Summary: The front right speaker channel sounds like it's trying to push all five channels sound through it. It crackles and kills audio quality. I've tried every change in settings to no avail. troubleshooting, I found that it was my HDMI two and three ports which were broken with one being even worse off than the other. Also, my right rear and right surround channels make beeping noises randomly while pushing audio. I can't recommend this receiver to anyone now.
Pros: The best looking receiver with good sound quality when it works. A big step up from my five year old JVC with no HDMI ports.
Cons: Beeping noises from speakers and two HDMI ports broken.
Summary: IF YOU ARE RUNNING HDMI AND HAVE A BLUE RAY PLAYER 3D COMPATIBLE DO NOT BUY THIS RECEIVER, HAS AUDIO AND VIDEO PROBLEMS WHEN RUNNING THE BLUE RAY PLAYER. THIS PARTICULAR MODELHAS A SOFTWARE UPGRADE AVAILABLE. IM IN THE PROCESS OF DOING THIS NOW. JUST A LOT OF AGGRAVATION FOR THE MONEY. THEY NEED TO MAKE THE BUYER AWARE OF THESE ISSUES.
Summary: I've had this receiver for just one year and it just fizzled out. It sounded good at first with good power and sound but then started to show problems. Just a little static at first which became annoying noise coming from the center channel. After that the unit stopped recognizing commands from the remote. Using the front panel of the receiver proved useless. Contacting Harmon service center with the warranty intact was just as useless.
Summary: First the good, the receiver delivered the high quality sound one would expect from Harman Kardon. It did not however play well with my 720p LG plasma TV or my 2nd generation AppleTV. After down-scaling the receiver's output to 720p so it would be visible on my 720p TV the HDMI signal still dropped out for a few seconds here and there, and about half the screen would constantly flicker video static.
Summary: I purchased this system to replace a 7.1 Pioneer A/V component receiver. This is my second HK, they have never disappointed - until now. It was just as easy to set up as my previous two receivers, plugging in speakers, HDMI, optical and RCA cables. The problems began almost immediately. The audio would cut out sporadically for a second or two, the video would do the same a short time thereafter, only for longer periods. Customer service... ah, what an experience.
Summary: It's MORE THA DIFFICULT to install, the menu to do it is so primitive. It's like from the stone age. I been trying to intal it for more than three weeks at no avail, and still trying. Up to now, I have done it partially... Only the radio -and it comes in the AVR-, the TV imposible to install, the DVD I did no even try to install, I don't want to try the rest. The users manual, it's so simple it's pitifull, less than basic.
Summary: I bought this item back in March, and had trouble from the start. My fault for not returning it sooner, I know. When watching a DVD (Blu-Ray or otherwise) the picture and sound would occasionally cut out completely, for several seconds. Sometimes when this happens, the "blackout" lasts for several minutes. Not much fun watching a movie when I have to keep my finger on the pause button of the DVD remote to stop the disc when the picture cuts off.
