Onkyo TX-NR5008 review

Onkyo has updated its flagship AV receiver for the 3D generation. We look for refinement amid the metal mayhem

Our Verdict

As a movie machine, it's a West End theatre capable of throwing a sonic envelope wide and loud; but it's also a sophisticated musician, at home with hi-res source material. While integration of new media sources could be a little more seamless, it's well worth an audition

For

  • Extensive codec support
  • network streaming for audio
  • ample connections

Against

  • Can sound coarse at very high volumes
  • net functions need further integration

When Europe's biggest AVR brand unveils a new flagship, it's time to take your head out of the popcorn bucket and pay attention. Not only has it outsold pretty much every other brand in the UK (and Germany) since 2009, but the Japanese marque has also consistently been first to market new AV receiver technology.

As I write it sounds as if cars are being lobbed into each corner of my viewing room. Onkyo's latest heavyweight, the TX-NR5008, is in full flight. The heavy metal objects landing around me are Iron Drones, dropping down to square-off against Shellhead and War Machine, for their climatic face-off in Iron Man 2 on BD.

What follows is 360˚ of bedlam, with ordnance panned every which way. The big NR5008 handles the DTS-HD Master Audio multichannel mix with thrilling precision. The wife complains that it sounds as if the house is being demolished. Welcome to home cinema sound on a devilishly large scale.

Feeling familiar

If you're looking for a radical form factor to usher in 2011, then you won't find it here. The TX-NR5008 is a cookie-cutter battleship, indistinguishable from last season's TX-NR5007. Unlike rival Marantz, which has applied an entirely new design aesthetic to its latest AV receiver range, there's no fresh ground being trod here.

Connections are extensive. There are eight HDMI inputs (including one under the fascia flap for a quickie console or camera hook-up), all of which are 3D capable (one of the key differences between this model and last year's NR5007 iteration).

Also new is a PC VGA/mini-jack audio input that helpfully outputs over HDMI, and with a view to family friendly integration, you get HDMI pass-through for those who want to play a disc without utilising the AVR. A pair of HDMI outputs is provided to feed both a display and a projector, simultaneously if you like.

Other niceties include Onkyo's Universal Port jack for iPod and peripheral accessories, Ethernet and USB (one on the rear, another under the fascia flap). Basically, if you need a connection, it's probably there.

Marketing Information

Onkyo's new flagship network receiver answers all your home entertainment questions-even some you hadn't yet thought to ask. The quality starts at the very foundations: a massive toroidal transformer, 22,000 µF capacitors, gold-plated terminals, and separate transformers for audio and video processing. Speaking of video, HQV Reon-VX offers the ultimate in 1080p upscaling via HDMI, while ISF calibration gets the best out of every video source. On the audio side, 9.2 speaker channels let you take advantage of lossless Dolby and DTS codecs, as well as expanded surround formats from Audyssey and Dolby. The extra channels also allow you to enjoy a multichannel source in your main room and powered stereo in two other zones. Connections abound, with eight HDMI 1.4a inputs, two USB inputs, and an Ethernet port for streaming audio from your PC or internet radio. To simplify set-up and adjustments, Onkyo provides a new overlaid on-screen display and Audyssey room correction.
