Onkyo TX-SR805 review

£699 inc VAT

Manufacturer: Onkyo

Our Rating: We rate this 4 out of 5

The Onkyo TX-SR805 is a home-theatre receiver that can decode HD audio formats, and produces the best audio we've heard outside of a cinema.

The Onkyo TX-SR805 is a home-theatre receiver that can decode HD audio formats, and produces the best audio we've heard outside of a cinema.

When Onkyo introduced its TX-SR805 home-theatre receiver last autumn, it was the only receiver capable of decoding high-definition audio formats - Dolby TrueHD and DTS Master Audio - which are part of the Blu-ray and HD-DVD specifications). These formats are to audio as high definition is to video, allowing discs to deliver extremely high-quality soundtracks.

Unfortunately, no Blu-ray or HD DVD player could output audio in Bitstream format, so the player - not the receiver - had to decode the Dolby TrueHD or DTS Master Audio audio, And that situation made the Onkyo TX-SR805's unique capability worthless (temporarily, anyway). Since then, however, a few players capable of outputting Bitstream have reached store shelves.

We tried out the £699 inc VAT Onkyo TX-SR805 with a £349 Panasonic DMP-BD30 Blu-ray Disc player, which can output Bitstream through either its HDMI port or its digital audio ports, thus enabling the receiver to decode high-definition audio.

The combination results in phenomenal audio--possibly the best you can get in your living room today. The Onkyo TX-SR805's price seems very reasonable given its capabilities.

Audiophiles want their best piece of gear to handle decoding so they can enjoy optimum audio quality from their system. Presented with a high-end DVD player and an inexpensive receiver, an audiophile would set up the system so that the DVD player, rather than the receiver, performed the video upscaling. Many Blu-ray and HD DVD players pale in comparison to high-end home-theatre equipment; if you're using one of these players with a surround-sound setup, it makes sense to have your receiver do the audio-decoding work.

Using the powerful, well-decked-out Onkyo TX-SR805 for decoding makes sense. It outputs 130 Watts per channel, can drive up to 7.1 channels, and has three 1080p-compatible HDMI 1.3 inputs (plus one HDMI 1.3 output for connecting a TV). The unit's massive transformer and heat sink contribute to its anvil-like weight of 23kg (the Blu-ray player we used with it weighs only 3.3kg).

The receiver works with Sirius and XM satellite radio, and can power stereo speakers in a second room (to handler that, however, you'd have to string speaker cables, probably through walls). The Onkyo TX-SR805 lacks an HD Radio tuner and can't pull in digital audio over a network (Onkyo's TX-NR905 adds network features to the mix).

The receiver comes with an adequate plastic remote that has backlit buttons. We occasionally had trouble using the center thumbwheel to navigate menus. And just before we returned the receiver to Onkyo, the spring-loaded catch for the panel that conceals lesser-used controls broke; the plastic retainer should be sturdier than it is.

We connected our Blu-ray player to the Onkyo TX-SR805, and used a Pioneer PDP-5080HD HDTV and NHT Classic Three 5.1-channel speakers as outputs. The receiver comes bundled with a speaker-calibration utility and a microphone. To calibrate, you plug the mic into a port on the front of the receiver and start the utility (which you can view on the TV screen).

The receiver produces "blat-blat-blat" test noises through each channel, measures audio level through the mic, and sets appropriate speaker output levels automatically. The calibration, which took about 10 minutes to complete, worked very well: output seemed perfectly set, even from the surround channels. You also have the option of adjusting the output manually via the receiver's onscreen controls. The controls aren't pretty - they look like a DOS screen - and they have almost no explanatory text.

The Onkyo TX-SR805's biggest problem is that it's such a complicated product. For example, when we tried to play DTS Master Audio tracks from a Blu-ray Disc, we could get the receiver to output simulated surround-sound formats - but not the DTS Master Audio - until we turned off the HDMI Monitor (video output) feature. But that meant we had to choose between watching a movie and listening to its high-definition audio; we couldn't do both at the same time.

After scouring the 120-page manual and fiddling with every setting we could find, we gave up and contacted Onkyo. A rep instructed us to turn off a setting that directs audio to be sent through the HDMI output connected to the TV; this setting was buried in one of the onscreen menus.

After we set everything correctly, the receiver showed a 'DTS-HD MSTR' message in LED text, confirming that it was driving five channels, plus the subwoofer. We couldn't find any Dolby TrueHD content in our library of Blu-ray discs, but we found several movies with DTS-ES and DTS Master Audio tracks.

The Onkyo TX-SR805 is an impressive product. Compared with other receivers in or out of its price range, it's a steal. Some audiophiles may sneer at the TX-SR805, because Onkyo is a midtier brand. It's certainly no NAD or Mcintosh, for example. But the Onkyo TX-SR805 costs a fraction of what a receiver from one of those companies costs - and neither of them makes receivers capable of decoding high-definition audio.
