1 out of 5 eggsThe unimaginable horror

Pros: Sounds Great

Cons: Flaked out and got really bad just 6 months into ownership. Onkyo's response? Ship me an empty box (receive in 7-10 days), and then it gets shipped to some 3rd-party authorized repair shop. Turn-around time? Unknown.

Other Thoughts: Just another review, like many others with problems. I've owned this for 6 months, but only used it for 4-5 months. It lives on a shelf with plenty of opportunity for air circulation.

It was working great, sounding great. And then... strange things started happening. Remote would not work unless I held it 2 feet or less from the front of the receiver. Other days, it would work from clear across the room. Last week it started a new behavior -- switching to strange mode combinations (like DVR Dock) and then not recognizing ANY front-panel button including the power button. Remote's batteries were changed several times, I also performed factory resets on both the receiver and the remote.

Now I've got to wait for the heart of my home entertainment system (primary TV, DVR and music) to be repaired for weeks, with no estimate of when it might be fixed (and based on other reviews... WHETHER the repair will hold...)

Just say NO to this box!

1 out of 5 eggsMajor Issue with TX-NR708

Pros: Worked well until it didn't.

Cons: Google the following to see a 300+ page discussion on problems with 2010 Onkyo Receivers on the AVS forum.
"The "OFFICIAL" Onkyo RC270, NR708,NR808, NR1008, NR5008, Integra 80.2 Failure Thread"

Other Thoughts: Shame on you Onkyo for not providing better customer support on known issues with these recievers.

1 out of 5 eggsWorked Great Until It Didn't

Pros: The unit worked great and switched up to 7 HDMI inputs. Plus it had a built in phono setting so I could still play my old records.

Cons: First thing I noticed was packing foam particles on the inside of the display window. That should have been a clue of upcoming quality issues.

Other Thoughts: After about 7 months of service the unit started flipping endlessly through listening modes (like THX, music, etc) all by itself. When that happened I couldn't even turn the unit off.
I drove it an hour into the city to an authorized repair facility for warranty service. They said they fixed some loose connections.

A few weeks after getting the unit back we had more problems. It turned itself on while we were shopping and switched to the "cable/sat" input. If I changed it to something else like TV a few seconds later it would switch it back to "cable/sat". Weird.

For those that might think it was errant IR signals the unit would do this even if I covered the front with my hands.

I even filmed it with my cell phone to show to the tech. He seemed puzzled. I'll post again if I ever get the unit working properly.

I have purchased Onkyo before and never had problems. But, I won't be purchasing Onkyo in the future.

1 out of 5 eggsWonderful when it worked

Pros: features

Cons: Locked up after 5 months of ownership. Remote won't control it, front panel buttons have no effect. Cycling power isn't even a reliable fix. It is an embarrassment to Onkyo.

1 out of 5 eggsHideous quality control - don't buy Onkyo!

Pros: Worked great for 6 months.

Cons: This and other Onkyo receiver models for the 2010 model year have known issues with the remote suddenly failing to operate the receiver - the remote is fine, the receiver has a failure internally that causes it to no longer receive commands from ANY remote - even a universal remote like a Harmony. Others have had issues with the front panel buttons failing to work including the power button, and some have had them fail completely going into a power cycle loop.

Other Thoughts: This is my first Onkyo product - and my last!

2 out of 5 eggsSome serious problems here

Pros: Great feature set to match up with my new Samsung 8000 3D TV. I've added more speakers to my system to have a really enveloping sound. The HDMI switching was one of the main reasons I upgraded from my old Yami 1000.

Cons: Zone 2 speakers only output sound from an analogue source, so I hooked up an old AppleTV to stream analogue music for my outdoor and workshop speakers. Didn't realize that at first.
Biggest problem was finding the 708 and TV "on" when we returned from vacation. We had not left them on! (Both were protected by surge protection.) Input selection didn't work anymore, so I took it in to the local warranty service center. They replaced a couple IC's. Hooked it all up again this afternoon. I set up and renamed all my inputs. Sort of tedious, but a nice feature. It worked fine for about 2 hrs, now it will not respond to the remote. I reset both, still nothing. Disappointing, to say the least.

Other Thoughts: I guess I'll pull it out of the entertainment center again, and return it for more warranty service. : (

1 out of 5 eggsOnkyo TX-NR706

Pros: Looks nice...

Cons: The worst receiver I ever had. It broke down 40 days after shipping from Newegg. When working, the sound was very low.

Other Thoughts: Not worth it for the price.

5 out of 5 eggsWOW - great buy

Pros: Lots of inputs, wanted to use with my Win t Media Ctr PC and it sounds better than I could have imagined. It was easy to set up. BUT, it could be could complucated if you go beyond the basics.

Cons: The on screen display is a little 1990s. This could really be improved.

Other Thoughts: Got it during the holidays for a great price.

5 out of 5 eggsTX-NR708

Pros: Sound quality
Network/Internet/USB (IPOD)
Zone 2

Cons: Not really a knock on this AVR, but in general the lack of feeding digital audio to second zone. I know it's rarely available in AVR's in this proce range...

Other Thoughts: It took me about 3 hours to disconnect the existing connections to my, roughly, 10 year old Panasonic [HA-SE70] and reconnect to the TX-NR708. Part of the delay was due to the fact that I'd hooked up the surround speakers to the Back surrounds which caused Audessy set up to fail. Keep that in mind when hooking this up...

Once I had the Audessy set up complete, I popped in The Dark Night Blu-ray and the sound, or rather sound field was incredible, it was so enveloping.

One of my reasons for upgrading was the HDMI capabilites of this receiver and it has been so nice to select an input ie- (SAT/CBL) and have everything switch over. Before I had to select the audio on the AVR then switch the remote over to the TV and select the source. My wife loves that!

Also love the Networking/Internet/USB features of this AVR.

Overall absolutley love this AVR, and I would highly recommend it.

FYI - I have my system connected to Energy Micro 5.1 speakers. It's as nice paring...
