Summary: I have had this thing since 2010, never had HDMI to really work right, now, it has totally stopped passing HDMI audio, which is all I ever got, the audio, was great when it worked. Trash!! Update, just ordered the Pioneer 1123K to replace this, I know HDMI was new when this device was made, but this really makes me sick, replacing a stereo and video receiver after three years, this thing should have lasted for 15 years or more.
Summary: I have been using this for a year and love it. Harmon Kardon is one of the best and this has been proof to me. I highly recommend it. I currently have this connected in my bedroom powering the 7.1 in-wall system. Love it.
Summary: I guess I've had this AVR for about 3 years now and it's been rock solid. For an AVR with its modest output specs it really kicks out the audio. For HT use it has plenty of power to drive my 5 NHT SuperZeros, which are not very efficient. It has and continues to work flawlessly. Setup was easy. Sound quality is great. Bottom line, if you can live without some of the newest features this AVR makes a great starter.
Summary: Well, it sounded good when it worked! I had immediate HDMI passthrough issues with every device I tried. I tried several Bluray players, a few streaming media players, and finally the PS3. None worked right. I had constant droputs of both audio and video. I tried contacting HK twice without any response from them. The third time I emailed them I actually got a response.
Summary: Purchased new just over a year ago. HDMI video is temperamental at best. Eventually video dailed completely and firmaware update doesn't help. Customer Service was horrible, warranty was horrible. This is the third HK receiver that I had purchased in 4 years. Never Again! Listen to the warnings of others that have posted trouble with HK receivers hear. Too many review it after they had it for one week.
Summary: I've had this Harmon Kardon AVR 1600 for almost 3 years. Auditioned this AVR in a Home Store with the ability to switch b/t a $3000 Yamaha AV Receiver and this little 50 watt per channel HK 1600 which was pushing Klipsch RC-52's. The thing I like about this little AMP over my old ONKYO 100 watts per channel (overstated?) is the clarity. Surround was already set up w/6.1 and the HK AVR 1600 allows for 'detuning' from 7.1 However, HK doesn't recommend it...
