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.

THE VERDICT
With support for all key immersive audio formats, 16-channel output, and Dirac Live room correction, the Monolith HTP-1 surround sound processor punches well above its price class.

It's been interesting to watch the evolution of Monoprice in the home theater market following the introduction of its Monolith product line. Monolith encompasses a broad range of components, including speakers, subwoofers, and amplifiers, all produced in partnership with big names in A/V product design and development, and all offering impressive performance at a strikingly low cost. The company's latest market disruptor is the Monolith HTP-1 surround sound processor, a stunning freshman effort that includes features typically seen only on components that cost significantly more than the $3,999 HTP-1.

THE VERDICT
Marantz’s new flagship surround processor makes the most of the Dolby Atmos, DTS:X, and Auro-3D formats while providing a notable sound quality improvement over its predecessor.

I remember my first flagship A/V receiver like it was yesterday. It was the year 2000, and Onkyo’s TX-DS989, which sold for a cool $3,200 and featured seven channels of built-in amplification plus support for the latest, greatest THX Surround EX and DTS-ES codecs was every home theater enthusiast’s dream. With rear surround speakers now added to the mix, a home theater could actually match the arrays found in cinemas.

THE VERDICT
Rotel returns to analog amplification for their latest top-of-the-line home theater machine—and the results are golden.

Is the Rotel RAP-1580 the surround receiver that dares not speak its name? In keeping with the two-channel distinction between stereo receivers and integrated amplifiers, Rotel calls it a surround amplified processor because it doesn’t include an AM/FM tuner. But to my mind, the defining trait of a surround receiver is that it combines a surround preamp/processor and a multichannel amp in one box. So I prefer to call this an audiophile receiver. You say tomato... [Editor’s Note: I’d call it a surround amplifier, and I don’t think it’s the last of this type we’ll be seeing...but, whatever.—RS]

THE VERDICT
The AVM 60 has everything you want in an A/V preamp/processor—and less. The stuff that Anthem has left off their more affordable pre/pro model contributes to simplicity and usability, and most buyers will end up thanking them in the long run.

For much of the home theater epoch, system builders who (for whatever reasons) have favored a separates-based system— built around an A/V preamplifier/processor and a suitable amplifier or amps—and have preferred such a system over the more usual A/V receiver approach have had, in essence, two choices. They could select one of a few very expensive, esoteric, high-end American or European designs, with the knowledge that they would probably lag a generation or two behind in HDMI version and latest-greatest surround and video processing. Or they could select a latest-model Japanese offering—recently, this has meant, effect-ively, Integra/Onkyo, Marantz, or Yamaha—and get more up-tothe-minute tech and more digestible pricing, at a certain cost in audiophile street-cred and (perhaps, depending on your belief system) sonic refinement.

THE VERDICT
A noteworthy addition to the high-end preamp/processor ranks, with Dirac Live a fascinating, must-hear plus.

Talar du svenska? Emotiva does. Enough Swedish, at any rate, for the Tennessee tenderer of direct-to-consumer A/V gear to bake Swedish firm Dirac’s speaker/room-correction DSP into its new preamp/processor, the long-awaited XMC-1.

If you’ll forgive a Miller analogy, Dirac is to Uppsala University as Audyssey is to USC: Dirac, too, evolved out of original academic electroacoustics research—although USC’s weather is better, and I’m pretty sure the Trojans could take the Swedes on the gridiron.

THE VERDICT
Krell’s aptly named, sonically sophisticated Foundation counters a foolish industry trend toward sacrificing sound quality for useless and/or redundant features.

We live in a bizarre world where automobile commercials tout peripheral accessories while omitting mention of engines, transmissions, and brakes. What’s more important: Stopping distance or voice-activated Bluetooth?

So it’s not surprising that in much of today’s home theater electronics, sound quality takes a backseat to features and widgets. Backseat? In some, sound quality doesn’t even go along for the ride.
