Behind the loudspeaker reviewed here is the story of a man with skill and interest in two seemingly unrelated fields: stonework and speaker design. Valerio Cora had the idea to bring those two fields together, and set about through painstaking development to bring that idea to fruition.

Reviewers' Choice Hi-fi as physical art—that’s a concept manufacturers (and consumers) have wrestled with since sound reproduction became a thing. To deliver music into a living space, you need speakers, an amplifier, and a source component. There are many ways to accomplish this. One way is to build the speakers into the wall and sequester the electronics in another room. This works reasonably well, but it would take a monumental effort to achieve the same sound quality as that delivered by a pair of freestanding speakers and some performance-driven electronics.

Reviewers' Choice About eight years ago, I was sitting in the lobby bar of the Hotel Bonaventure in Montreal, Canada. It was the Saturday night of the 2017 Montreal Audio Fest, and the bar quickly filled up with many of the exhibitors. I recall that particular evening as a time of easeful conversation lubricated by very good local beer. I spent a good hour chatting with Harry and Mat Weisfeld of VPI Industries. That father-and-son partnership made for good company—Harry’s quiet and calm demeanor, along with his wealth of analog knowledge, paired perfectly with Mat’s unbridled enthusiasm.

I’ve owned a record player since I was 13 years old—1976, if I remember correctly. That record player became a turntable about four years later, with my acquisition of a Technics SL-B2 standalone deck. The Technics begat a Rega, and the Rega begat a Roksan. From Roksan to Pro-Ject, then from Pro-Ject to VPI, we arrive at the present.

Reviewers' Choice I’m not sure I’m the right guy for this job. With all the reviews I write for SoundStage! Ultra, I never cease to be conscious of how expensive these products are. Speaker cables that cost more than a car. Preamplification components that could put my daughter through a year of private school. Every Ultra-class component that comes through my house and my system is a reminder that I’m not rich.

Danish loudspeaker manufacturer Audiovector, launched by Ole Klifoth in 1979, introduced an audacious wedge-shaped cabinet that year that broke away from the conventional boxy designs of the time. Unlike rectilinear cabinets, which are susceptible to internal standing waves, Audiovector’s design had no large parallel surfaces, thereby effectively eliminating this problem. It also had a back-leaning baffle that ensured phase alignment of the drivers. While tilted baffles have been featured in speakers from other brands, the Trapeze design was unique and remains unparalleled.

In this month’s editorial, I spent a fair bit of time relating how I perceive certain products in the world of high-end audio. I didn’t dwell much on sound quality, although that aspect of performance is obviously the most important factor when choosing an audio component. But still, there’s more than sound quality to consider.

Reviewers' Choice In today’s overcrowded hi-fi market, quality products can sometimes be difficult to identify among the many run-of-the-mill offerings. Every so often, though, an audio component is of such exceptional quality that it stands out. A few such outstanding performers can be found in digital audio, from brands such as Chord Electronics, dCS, MSB Technology, and EMM Labs, which eschew off-the-shelf DAC chips, choosing instead to develop their own DACs. The result? Some of the finest digital playback available today.

The world of fanciful, unlikely, unbelievable audio tweaks is constantly evolving. Over the years, we’ve had such outlandish concepts as the Beltist idea that wrapping your cold-water pipes with solder wire will improve the sound of your system, as will parking your car in the driveway facing out. Next came little dots that you place on your walls to . . . do something, I guess.

The power amplifier is the tough guy of the audio world. A good power amp is quiet, solid, and powerful. There are no moving parts in an amplifier. It does one thing only, and, if it’s a good one, it does that with grace, strength, and purpose. My martial-arts teacher, a quiet, solid, powerful Korean gentleman who’s now in his early 80s, says that while you can’t always tell who is tough by looks alone, it’s pretty damn easy to determine who isn’t tough.
