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.

Emotiva. The name sounds like the latest cure-all marketed by Big Pharma on the evening news programs. (Remember “restless leg?”) It is, in fact the consumer-audio brand of Tennessee’s Jade Designs. And Jade Designs, in turn, is the direct-to-consumer brand founded by a longtime veteran of the rough-and-tumble electronics OEM (original equipment manufacturing) world.

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.

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.

It’s a fact of modern life. The higher you climb in the high end of anything, the less, at least in one sense, you will get. You will find, I believe, few gargoyles on buildings designed by I.M. Pei, and even fewer rear-seat DVD screens in Paganis.

Over a decade ago, while writing for a now-defunct audio magazine, my editor shipped me a pair of monoblock Cary tube amps he’d never gotten around to reviewing. Something must have shook loose during transit, because instead of music, all I got when I powered them up was a wisp of smoke as one monoblock sadly committed hara-kiri! The Cary Cinema 12 and Model 7.125 are an eternity of light years away from those fragile forays into bottle socketry. They exude an air of quality and reliability that physically and musically justify their significant price.

Call me weird, but I get excited when I see XLR connectors on my audio gear. Time spent in my fledgling home studio has taught me why pros prefer them. The Cinema 12 offers both single-ended RCA and true, differentially balanced XLR outputs, an arrangement and circuit design mirrored on the Model 7.125 amplifier. The Cinema 12 even offers a pair of stereo analog XLR inputs and a single balanced digital input beyond the roster of seven single-ended analog input pairs. Audio purists will appreciate the fact that you can bypass all digital conversions for your analog sources, including the 7.1 analog input you might use with an SACD player.
