Onkyo TX-SR605: HDMI 1.3 and next-gen surround decoding, for an amazing $600
(Credit: Onkyo USA)For the past 12 to 18 months, astute readers may have noticed an increased bit of hedging in our reviews for AV receivers. Yes, even low-end receivers offer more features and flexibility than $1,500 models did just three or four years ago and yes, there are plenty of great-sounding receivers available out there at great prices. But smart shoppers looking for a no-compromise, future-proof AV receiver have been stymied, even if they've been willing to pay upwards of $2,000.
At least, that was the case--until today. Onkyo has become the first mainstream manufacturer to officially announce an array of home audio products that offer the two big features that have been MIA on home audio products to date: HDMI 1.3; and onboard decoding of Dolby Digital Plus, Dolby TrueHD, and DTS-HD Master Audio soundtracks found on HD DVD and Blu-ray discs. The news itself wasn't a surprise, as most of the details had been leaked on the Web earlier this month. And there is no doubt that other manufacturers will be announcing similarly equipped receivers in the next few weeks and months. But because specs, pricing, and availability have been confirmed, we can now say authoritatively that Onkyo looks to be offering some of the most exciting--and surprisingly affordable--A/V receivers seen in recent years.
Full specs for each of the seven announced receivers are highlighted below. In addition to HDMI 1.3 and Dolby TrueHD/DTS-HD support (on all but the two low-end models), most offer support for XM and Sirius satellite radio (with the respective subscriptions and accessories). All seven models offer Audyssey automatic speaker calibration, 7.1-channel analog inputs, at least two HDMI inputs and one output, and compatibility with Onkyo's iPod docks.
The 2007 Onkyo receiver lineup is as follows (note that this is nearly identical to the leaked specs published earlier this month, but with confirmed/official details and pricing; all models are available in black or silver):
TX-SR505 ($380, now available)
7.1 A/V receiver, 75 watts per channel
2 HDMI inputs (video passthrough only; audio requires separate connection)
Audyssey 2EQ auto speaker calibration

TX-SR605 ($600, May 2007)

THX Ultra2 Certified

The whole lineup is impressive, but the sweet spot--especially for those on a reasonable budget--definitely looks to be the TX-SR705 and TX-SR605. Given their amazing feature sets (including options that were heretofore unavailable), their $900 and $600 price points are downright disruptive. While a hands-on evaluation is needed for a final determination--and, to be sure, CNET's on the list for one of the first SR605 review samples--the mere existence of both receivers makes anything else in the sub-$1,000 range pale by comparison (sorry, Yamaha). Personally, I'd hold off buying any A/V receiver until we determine if these Onkyos--and their eventual competitors--can deliver on their groundbreaking potential.

CNET editors' buying advice
We have not reviewed this product but here is CNET's buying advice on AV receivers. This content was chosen based on the features included with this model of av receiver.
High-end AV receivers ($600 and up)
Audio/video receivers differ quite a bit from old audio-only stereo receivers you might be familiar with. Almost all models have the baseline home theater capabilities: video switching, 7.1 channels of sound, and basic Dolby and DTS surround decoding. And even many inexpensive receivers now utilize HDMI inputs and outputs, which offer the potential for all-digital audio and high-def video hook-ups on a single cable.
In a perfect world, power ratings would give some indication of the loudness potential of AV receiver. But unfortunately, not every 100-watt-per-channel receiver is created equal. What's inside does make a difference, and beefy power transformers and capacitors are not only heavy but also expensive; that's part of what you're paying for here. And while the THX certification is mostly a marketing gimmick, it's usually a sign of more-honest power ratings--although you shouldn't pay more just for THX.
Some high-end receivers have Ethernet or Wi-Fi connections through which they can stream audio or Internet radio on a home network. Since these features can be added to a home theater system with the purchase of a separate media streamer (such as the Apple TV or Logitech Squeezebox), there's little advantage to paying extra to have them bundled into the receiver itself.
Look for a receiver with as many HDMI inputs as possible, and one that offers analog-to-digital video conversion (sometimes called "HDMI upconversion"), so any non-HDMI AV sources will still appear on the receiver's HDMI output. Also, avoid receivers that offer only "HDMI video passthrough," which means that the audio soundtrack requires a separate cable. For those models with analog-to-digital video conversion, you'll need to make sure the system also has a good video processor (just like a DVD player). Poor processors mean ugly looking video from non-HDMI analog sources (such as the Nintendo Wii or an older DVD player); the better the processing, the better the image conversion from those sources.
