Summary: I previously owned a Pioneer receiver. It lasted a short time for me when it stopped sending video thru the HDMI. The clarity and sound effects of this receiver far surpasses anything I've ever owned. I've only had it for a month, so far I'd say you'd do we'll purchasing this model.
Summary: First off, I am not a huge audio guy... I just know what sounds good and what doesn't. I run a very simple setup at home... 2 Klipsch KG4's, a big Klipsch center channel speaker, and a 10" Klipsch powered sub. The KG4's each have a 12" woofer on the back, in addition to twin 8" woofers and a horn on the front... they pound. My dad is bringing over his Forte's next week...
Summary: This is the first received I've owned. I connected it to a 7.1 channel in-wall surround sound system and paired it with a Yamaha subwoofer then added a 55" Samsung Smart television. We now have an excellent theater system in our new living room. Very simple to connect all the components and the sound is impressive. Now to learn how to tweak the system to its full capabilities!
Summary: I am too old to get into a lot of minutiae when it comes to audio; first I remember the audio wars of the 60s/70s; secondly, my hearing is now 60 years old. I got this to replace a 4 year old Onkyo; worked well enough when it did; but it got senile and started losing its settings. When this came up as a Gold Box deal, I grabbed it. Glad I did.
My 2 cents after 20 months of ownership, great receiver/amp

Summary: Update August 21, 2013. Seeing more than I expected number of reviews stating this Receiver fails after a year or so I wanted to advise I have my TV picture & sound running through the V671 via hdmi cable along with CD player, Blu-Ray and newly purchased AppleTV. This means my Yamaha is turned on & off whenever I watch TV which is at least daily. No problems.
Summary: Bought this unit to replace my 10 year old RX-V495 which is still kicking. Power button on the remote conked out about 2 years ago and it's hardly been turned off since then. What a trooper. I first got the 671 from a big box store after watching the price here and comparison shopping for a couple of months. One week after I purchaced it from the big box store Amazon dropped the price by alot.
Summary: I waited about 60 days before completing this review. This receiver replaces an Onkyo TX-SR605 which also was a great receiver. My mistake was updating the Onkyo TX-SR605 to a Onkyo TX-NR616. While I do not want to turn this review into a bashing of the 616, I had two of them and there was nothing but problems with them. Yes, I did the firmware updates, yes I know AV equipment. There was just one issue after another with both of them so returned and tried Yamaha.
Summary: This receiver was easy as pie to set up with supplied pictures. It comes with a DVDrom manual but I haven't used it yet because it works fantastic just as it sits. I was unprepared for the fact that the image quality would get better using my receiver HDMI switch as opposed to my external switch. I know my other receiver was getting old but this is crazy how much more in depth the sound is. I am very impressed.
Summary: I am very happy with this receiver. I have had it for about 2 months with no issues. It replaced an RX-V467 that I had for about 2 years with no problems. I just decided to move up to 7.1 and Internet capabilities. Sold the 467 and got a great deal on this 671. Didnt care for the YPAO setup which I ran 3 times and got 3 different setups. I just set it up manually and it sounds great.
