Summary: This is a unit that performs very well if you can find one, The down side is that it runs very hot (you can burn yourself if you touch it) and it has reliability problems that I think stem from the high operating temperatures. Also it can not process 3d video. I installed it with a lap top cooler under it and a 8 inch fan on top. Runs cool. For 3d I installed a HDMI switch to bypass the unit in 3d mode and use a digital audio feed to the unit.
ONKYO will fix sound issue for free outside of the warranty!

Summary: This is a great receiver with excellent sound. However, after 4 years the sound quit working completely. Come to find out this is a widespread problem. So widespread that onkyo is covering the problem free of charge through 2018. I found this information on onkyos forum at http://www.onkyousa.com/Support/service_info.php I purchased my unit in 2010. They are sending out a shipping container with a prepaid label. Hoping to get it back quickly.
Summary: I was happy until it stopped working. Known design flaw where the HDMI audio switching components fail, leaving you with a receiver that cannot produce any sound. Onkyo customer service will do nothing to help you, even though their design is at fault. I'll never buy Onkyo again. Marantz and other brands offer better reliability and better sound quality.
Summary: Loved this unit for the first several years I owned it and then one day: no audio (small problem for a receiver, don't you think?). In any case, this unit as well as the xxx8 and xxx9 series have a known issue with heat and their HDMI cards. Basically, these units run quite hot and eventually they fry their HDMI boards.
Summary: I have owned this receiver for just over a year now and was impressed. Now this unit failed and the research is showing a KNOWN issue with the HDMI BOARD. Onkyo needs to step up and take responsibility for this known problem. They fail all the time and cost $800+ to replace! STAY AWAY FROM THIS BRAND...
after owning for 3.5 years onkyo repaired for free
14 November 2013
Summary: have owned this receiver 3.5 yrs now, hate it, dosent work, do a internet search for nr3007 no sound before buying this receiver updated: onkyo came thru and stood behind this product, put a new hdmi board in for free after warranty had been expired for 1.5 years, its fixed and rockin the house again
Summary: Worked great for a year then started with no sound when first starting. Frustrating - contacted Onkyousa and they said they would pay for a repair as it was only 30 days outside a 1 year warranty! had to drive it 200 miles south into Mass where they kept it for almost 2 months - sent it back to me and reinstalled it and it worked fine for about 30 days when it started the same thing again! Have to turn it off and on a couple of times to get the sound working!
Summary: It is not every day that I dump an AV receiver in the trash, but that was the fate of the Onkyo NR3007 that I purchased from Amazon.com. This is already an old model hence the feedback may not reach most potential buyers of Onkyo products, but I strongly sugggest you google "onkyo no sound" or variations thereon to see the many dissatisfied customers who had QC experiences with this model.
