Summary: Horrible!! ..I bought this in 2012 so my warranty is void. Here's the thing. I heard complaints about the Tx series and I thought the unit caught a virus through all the info read on the net. It's just a matter of time til that happens I taught so Inever hooks this system up to the net. Boy was I wrong. 1st. What an excellent system with the 110 RMS and excellent sound and video. 2nd. What a shame to pay $500 and have it fail in 4 years.
Summary: Well, I honestly wish I wasn't bashing this product. I bought it in a departure from 2 Denon Receivers that I have had forever. The first lasted me literally 20 years and the sound was incredible. I upgraded to get better features for the video and upgrade to 7.2 The other Denon is still running in the other main video room and it is a 5.1 that is still running strong 10 years later.
Summary: As others have written I will do the same. I really like Onkyo - this was my second. I upgraded 3 years ago with high hopes; in fact I was impressed and enjoyed the NR709. Then about 2 weeks ago, I noticed the audio was taking a few extra seconds to click in, then finally nothing. I use HDMI for my entire network and had read the HDMI boards were failing in some models. I'm still not sure what failed, but audio output just stopped working.
Summary: More problems with this unit in 2 years (sound goes out - like no sound from any source - no indication of connected speakers; constant 'second long 'flicker' where sound and picture 'disappear' for a second while watching DVD's or movies), than in 20 years with my old Onkyo unit (TXSV70PRO). Buttons are not illuminated, so it is very difficult to see which button does what.
Summary: My unit also failed shortly after warranty period was over. Same HDMI sound problem as of many others who are complaining in various forums. I should have taken my time to do a proper research on these reported problems. There are so many similar complaints around the web that I believe it should be a known product defect. Interesting fact is that same problem did exist on previous generation models and they have not bothered to fix it. What is worse?
Summary: Got this receiver almost 22.5 months ago. I had no issues or complaints with it, until about 2 weeks ago when all of sudden there was no audio output. I called the company, who had me take it to the nearest repair shop (1.5 hr drive round trip -with no traffic). They repaired it for free (repair guy said that this was a common problem with these units)... (SIGH) For the $550 I paid for it and having major issues after less than 2 years...
Summary: Well be aware, mine just broke just after 2 years. There is reason these are cheap. Turns on, but no music on either speaker nor headphones not even from tuner. Warranty just expired, build in obsolescence I assume.
Summary: This is one of the waste product. HDMI handshake fails repeatedly. I live in NJ and luckily there is service center in 50 miles . There was fire in receiver for TWICE and was repaired. As soon as it was returned to me HDMI is never recognized. Its one year old now but its really waste of time and money. Buy Denon. Good bye Onkyo.
Summary: Was so happy to purchase the TX-NR709. It lasted me about 1.5 years (I guess I should be thankful). Mysteriously, it decided to no longer play sound. It passes through sound to my TV speakers but won't play through the system. Restored factory settings and Audyssey won't run. It tells me to wait. I've waited for a couple weeks. We've been waiting together. I fear the 709 is going to win the battle of patience as I'm ready to go Office Space on it.
