HDMI 1.4a Support for 3D Video and Audio Return Channel
The eight HDMI 1.4a inputs on the TX-NR5008 let you simultaneously connect high-def sources such as a Blu-ray player, gaming consoles, and a cable/satellite tuner. And the two HDMI outputs let you send a pristine signal at the same time to two different high-resolution displays. As the latest version of this connector, HDMI 1.4a adds the exciting possibilities of 3D video and an Audio Return Channel. 3D video is the next big thing in home entertainment, with movie, game, and broadcast content on the increase and 3D-compatible TVs coming to market. The TX-NR5008 also offers the convenience of an Audio Return Channel via HDMI. Audio content received directly by your HDTV’s tuner can be sent "upstream" to your A/V receiver, without the need for a separate S/PDIF audio cable.
PC Audio and Internet Radio with DLNA 1.5 and Windows 7 Compatibility
As one of Onkyo's new breed of receivers that can link directly to the Internet or to your home PC via a local network, the TX-NR5008 takes streaming audio and Internet Radio to a whole new level. MP3, WMA, WMA Lossless, FLAC, WAV, Ogg Vorbis, AAC, and LPCM audio files--whether on your PC or from the internet--can now be played back through your main system with unprecedented power and fidelity. The TX-NR5008 brings to life a huge array of Internet Radio channels from Pandora, SIRIUS Internet Radio, vTuner, and more*. As well as being compatible with earlier platforms, the receiver is compatible with Microsoft's Windows 7 platform, which includes the DLNA 1.5-specified "Play To" media-streaming feature. Another benefit of having the TX-NR5008 connected to the Internet is that you can then easily update its firmware.
THX Ultra2 Plus Certified
The ultimate benchmark for home audio performance, THX Ultra2 Plus is specified for rooms where the screen-to-seat viewing distance is more than 12 feet and the room volume is 3,000 cubic feet or greater. To achieve THX Ultra2 Plus certification, the TX-NR5008 must meet the world's most demanding standards for home theater audio quality and performance, and must play at reference volume levels with minimal distortion.
Advanced Video Processing and 1080p Upscaling with HQV Reon-VX
HQV Reon-VX is the most sophisticated video-processing chip available for home theater. It provides the ultimate support for 1080p scaling; for filtering of jaggies and artifacts; and for the reduction of random, "mosquito", and block (codec) noise. HQV Reon-VX also enables color region enhancement and the rendering of more than one billion colors.
VLSC (Vector Linear Shaping Circuitry)
Onkyo's VLSC employs a unique digital-to-analog conversion circuit to mitigate the effects of signal noise. Data is converted between discrete sampling points, which are then joined with analog vectors in real-time to produce a continuous output wave form. The result--a noiseless, smooth analog signal based on the digital source.
Harnessing Power for Audio Performance
Onkyo's H.C.P.S. (High Current Power Supply) concept is based around power transformers with the capability to respond to the wide dynamics of home theater. In the case of the TX-NR5008, a massive toroidal transformer improves power efficiency and radiates very little noise into the surrounding circuitry, while two separate transformers cater specifically to audio and video processing. You’ll also find capacitors (operating at up to 22,000 microfarads) that store the charge necessary to support an effective power supply, along with large new custom-designed transistors to drive high currents.
Customized Audio via Audyssey and Dolby Technologies
The TX-NR5008 is equipped with MultEQ XT32, Audyssey's most powerful room-correction technology. MultEQ XT32 gathers frequency and time-domain measurements from up to 8 positions in the listening area, to help create a clear, well-balanced, and natural sound. Two other Audyssey technologies, Dynamic EQ and Dynamic Volume, work to optimize frequency response and dynamic range at all volume levels. In a similar vein, Dolby Volume performs independent loudness adjustments to different frequencies and channels to produce a listening experience that includes all the dynamics of the original mix at whatever volume you choose. It also offers the option of maintaining playback volume at the same user-chosen level across all input sources.

Most Helpful Customer Reviews
Like many "gear heads" a great deal of research online and in various A/V mags went into the prep for purchasing a new receiver for my dedicated home theater. I had been a pretty loyal Denon owner in the past with my last one being the 3808ci. It was a great unit but I wanted a new receiver with the Audissey x32 that could better calibrate for new front high and wide speakers. I also wanted the newest HQV Reon processor for enhanced upscaling of video. Frankly, this Onkyo was much more price efficient than the current Denon equivalent. I took the leap and purchased thru Amazon...one of my best decisions of 2010! It did take me a couple of shots with Audissey, playing around with the microphone positioning; but, the end results were fantastic. My Paradigm speakers never sounded so full and brilliant. The depth and soundstage this receiver creates blows away any receiver I have ever had. A couple of key features for me...1) a full rich soundstage even at lower volumes; 2) the THX Ultra2 Cinema settings... Hats off to Mr. Lucas!... I have never been a fan of using "enhanced" preset sound settings but this is absolutely amazing. If you have at least a 7.1 speaker setup this setting will transform your typical hohum cable TV 5.1 Dolby into a 7.1 aural soundfest! I have found that when I have guests over to watch a blu-ray in 5.1 DTS Master HD, and the back row seating is occupied, near the back surround speakers, I will use the THX to bring the back surrounds to life for them. They love it, and IMHO there doesn't seem to be much, if any, loss in sound integrity. A similar setting, THX Cinema, will even make the inherent 2.0 sound from sources such as Netflix or Amazon VOD come to life. Of course, this is all just my opinion but for this home theater junkie it's like heaven. Oh, and BTW the video upconversion is excellent too. In this price and category, I believe you are unlikely to find a better A/V Receiver; the equivalent...maybe; better... I don't think so... Do your own due diligence and enjoy whatever your purchase may be!

This is the 3rd Onkyo receiver I have purchased. The other 2 didn't die, they just became outdated. I was originally looking for a couple models below this level, but the Amazon virtually half-price made this lower priced than than those, and an absolute bargain. My only negative is that using Zone 2 or Zone 3 doesn't allow you to use the full 9.2 channels, but being able to pump out internet or computer tunes to the pool for the kids while still being able to watch Bluray movies in 7.2 THX definitely outweighs the negative. The receiver was very easy to set up and it's filled with the latest technology. If you plan to use the internet and network connectivity I highly recommend purchasing the Netgear XAVB5004 Internet Adapter. It streams at up to 500Mps, works off of an electical outlet, and allows you to connect up to 4 devices to it. I never experience any speed degradation with this combination.

I have had the Onkyo TX-NR5008 for about 4 months now.
My past experiences have been with a high end Yammie, a mid level
Pioneer, Sony's, Akai, Teac, others. This is by far the highest end
receiver I have had. I have yet to fully explore the potential of this
receiver as I have not hooked it up to my network. I am still
discovering which sound processing (or none) I prefer for music, movies,
games, etc. With the choices available it's a lot of fun.
1st off this thing is a TANK. Really it has a firing rate of... well
O.K. it's not actually a tank but it is very heavy and pretty big.
You'll need a good space for it to fit and breath. I have never had any
heat problems but some people complain about the heat of this unit. My
only complaint is how cumbersome it is. And that might not be a bad
thing as it has a toroid transformer which I do not know if I would
notice the audio difference from a standard transformer. But on paper it
is apparently better.
One of the major reasons I purchased this receiver aside from the build
quality was video capability. It has plenty of HDMI ins and outs (I only
need 1 out and three ins) but there are more if needed. The 5008 also
has video upconversion or the ability to do a straight pass through.
This is great if your source is clean and has the resolution you want.
You can also adjust the white balance and video noise of the signal on a
PER SOURCE BASIS. Very cool.
A friend of mine challenged me to run a little volume test. I couldn't
run from the challenge. So we cranked up some Rush to ear pearceing
levels and neither the 5008 nor my Axiom M-60's broke a sweat. We were
bombarded with a wall of blazing drums, screeching guitar, and of course
funky bass. It was like front row in a rock concert! The TX-NR5008 will
deliver, just make sure you have speakers that can take it.
What about low levels? I can get very tight and defined bass at low
volume levels. This could be a combination of the speakers and the
receiver, but whatever it is it is working.
As the centerpiece of my home theater I am very confident in the quality
and performance of the Onkyo TX-NR5008. It is a receiver that I chose
over other brands for many reasons. Build is one of them, along with
features, power, and reputation. I did a lot of research and listened to
a few good receivers. The Onkyo won by a large margin. I'm happy with
the purchase and have not been let down one bit. Do your own research,
don't just take my word for it. You may choose another product. However
if you choose the Onkyo I'm sure you'll be completely satisfied with
it's capabilities and performance. I highly recommend this receiver.
***update***
A few points to add as I have been combing through the manual. The TX-
NR 5008 also features some very advanced volume correction utilities:
Dolby Volume control and Audyssey Volume control. Both are basically
regulating volume fluctuations. For example when a commercial comes on
and it is way too loud so you turn the volume down. Then of course your
program dialogue gets lost and you turn the volume back up, etc. They
aid in controlling that dynamic.
Additionally they moderate tonal fidelity at various levels. What this
means is that when you turn the volume up or down these process the
signal at various bandwith frequencies so that you do not miss various
sounds at low volume.
Other notes: You can utilize a 2nd and 3rd zone on the TX- NR 5008. The
zones allow you to use a set of speakers in another room or patio etc.
The speakers can be directly wired to this Onkyo or a set of RCA cables
can be used from the 5008 to an external amp. Your choice!
I had previously forgot to mention one other major part of the video
upscaling: the 5008 uses the HQV Reon-VX processor. One of the highest
regarded video processors currently available. There are other video
processors in other receivers. The preference is really up to the user.
The HQV Reon-VX takes any video source from any video connection and
allows you to upscale to 1080p (or lesser or none). I absolutely based
my purchase on the video upscaling as the key to my home theater needs.
Also the white balance control was vital (many t.v.'s lack white balance
adjustment). BTW all 8 HDMI inputs are 1.4 for people that are
interested in 3D.
As mentioned around the internet in reviews, etc. This receiver is a
powerhouse at 145Watts into 8ohms. It is NOT for the feint of heart.
Also, it is rich in very advanced features. But along with all that
muscle and brains it is balanced with definitive quality and form. I
have no hesitation recommending the Onkyo TX-NR5008 as the director of
any mid to lower high-end home theater system where separates would be
the only step forward.
