Surround Processor Reviews

Separates Are What Keep Us Apart

Back in the days when CRT front projectors roamed the earth, any serious home theater required a separate surround processor and amplifier. In fact, it wasn’t uncommon to find a Tri-Amplisauri from Parasound, Proceed, and others covering those three all-important front channels. Of course, technology has advanced significantly in the past decade. These days, unless you have some very special needs, you can’t go wrong with today’s powerful and reasonably priced one-piece receivers. Many have more amplified channels than Hillary Clinton has pant suits. Rotel makes a number of A/V receivers. I even reviewed one for UltimateAVmag.com a few years ago. But the separates I reviewed here are not simply a case of cutting the baby in half. This here is a new species.

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.

THE VERDICT
Rotel's RSP-1576MKII lacks some features you'd expect to see on a surround sound preamp/processor circa-2021, but audiophile-grade sound quality and Dirac Live Full room correction help make up for any deficits.

Any new surround sound processor circa-2021 is bound to have a heap of demands placed upon it. Along with support for the latest immersive audio formats—Dolby Atmos, DTS:X, etc.—there's music streaming, Auto EQ/room correction, and HDMI video switching of the latest 4K/high dynamic range video formats. And because a surround sound processor serves as the main user interface in an A/V system, ergonomic considerations are paramount—how easy is it to switch between sources and tweak audio settings like surround, subwoofer, and center-channel levels on the fly?

Grander than ever.

While Sunfire's Bob Carver isn't quite the household name that Apple's Steve Jobs is, he absolutely qualifies as a bona fide audio legend. Carver's greatest hits range from his early high-power amplifier, the 350-watt-per-channel Phase Linear 700, to Sonic Holography, Bob's virtual-surround generator. Carver also did much to inspire the new breed of super-potent, ultracompact subwoofers with his much-copied Sunfire True. His knack for audio innovation pumped my expectations for a couple of his latest creations, Sunfire's Theater Grand TGP-5 pre/pro and the TGA-5400, a 400-watt-per-channel amplifier.

THE VERDICT
The Altitude16 may be a luxury purchase, but for those seeking an upgradeable surround sound processor with fantastic sound quality, cutting-edge room correction, and support for all the latest immersive audio formats, it's a true standout product.

I've been reviewing A/V gear for over 15 years, and it's rare that something new comes along that will intimidate me. But all that changed when I found out I'd be reviewing the Trinnov Audio Altitude16, an $18,000 surround sound processor offering up to 16 discrete output channels plus the company's proprietary Optimizer speaker/room correction, that's arguably the most sophisticated and flexible offering of its kind on the market.
