THE VERDICT
Yamaha’s new pre/pro is a surefire contender, though its matching 11-channel amplifier wasn’t quite the same caliber.

If you’re in the market for a new AVR, you can spend countless hours researching all of the various manufacturers’ Websites and, when all is said and done, still have 20 or more models to choose from that have all the bells and whistles you want. The same can’t be said for the surround processor market, which is extremely limited by comparison.

Most companies offer only one model—if that—and it’s generally a reconstruction of their flagship AVR minus the amp section. Don’t expect a discounted price, though; with such a limited audience for pre/pros, you can expect to pay top dollar even when the amps are absent. That said, this isn’t such a bad deal because you can then choose an amplifier that mates well with your particular speakers. Furthermore, by having the electronically noisy amps in a separate enclosure, energized by their own dedicated power supply, you can theoretically enjoy improved audio quality. Of course, you also get an increased footprint in your rack with additional black boxes. The quest for audio nirvana certainly isn’t easy.

As A/V enthusiasts, we are constantly on the lookout for the best audio and video we can find, and when we reach that state of nirvana, we enjoy our equipment until the next CES or CEDIA when we then hear about something new and begin to worry that our system will soon be second best. Writing for Home Theater makes me an unwilling accomplice in this never-ending cycle of upgrade-itis, but truth be told, I’m just as affected by this as the rest of you. Thankfully, I’m able to get my fix by having lots of equipment moving through my rack, but every now and then, I fall in love with a piece and don’t want it to leave my possession.

Price: $3,500 At A Glance: Enormous power output • Remarkably compact • Class D

Class D amplification has a narcotic-like hold on the audio electronics industry. These switching-mode designs mesmerize with a dazzling array of advantages: high efficiency, high power output, low weight, compact dimensions, and depending on implementation, enormous cost savings.

Do you dream in surround sound? Since you’re reading this magazine, the answer is probably yes. Psychiatrists say dreaming is good for you. Thumb through any issue of Home Theater and you’re more likely than not to encounter components, systems, and lavish, dedicated rooms equipped with the latest 4K projectors and high-powered, surround-sound systems that most of us can only dream about.

Price: $4,400 At A Glance: 4K scaling • Reference-quality video processing • Audyssey MultEQ XT32 ups the ante for room EQ • Nine channels of THX Ultra2 amplification

I don’t know what’s more impressive, the fact that Integra can produce a new state-of-the-art surround processor each year, or that the company can find new audio/video processing modes to add to its already ridiculous list of features. The Integra DHC-80.3 is the latest home run from Integra, with some of the most future-proofing features the company’s delivered yet. I can’t imagine adding much more to a surround processor, but I’m sure Integra will pull some new surprises out of the bag next year.

I’ve reviewed several of the past incarnations of Integra’s A/V processor, but this time up, Integra also sent out its nine-channel THX Ultra2–certified amp, the DTA-70.1. This monster delivers 150 watts per channel and sports balanced inputs and a gorgeous solid-aluminum front panel that matches the DHC-80.3 perfectly.

The Ladder to the High End

You’ve got to have sympathy for sound- and build-quality-oriented A/V electronics manufacturers like Rotel. You can go online, and for four hundred bucks and change buy a “630-watt” 7.1-channel AVR from a big-name manufacturer with all the latest lossless audio decoding from Dolby and DTS, video processing, 1080p HDMI switching, upconversion, and more. Since many people these days don’t care about good sound and because they’ve never actually heard it, they think, “Everything sounds the same.” And they think they should get it all for a pittance.

Core Audiophile Values

During the last decade or so, specialty audio manufacturers have seen the marriage of home theater and high-performance audio become contentious at best and life threatening at worst. These days, companies have fewer financial resources and longer R&D lead times. Relatively small audiophile-oriented companies that sought the A/V path have been overwhelmed. Sometimes, fast-moving, shelf-life-shortening developments­—such as the adaptation of new audio and video formats—have burned these companies outright.
