In 2023 I visited Vertere Acoustics, a small London-based manufacturer of turntables and related products. The company was founded in 2006 by mechanical engineer and turntable designer Touraj Moghaddam after he separated from Roksan, a company he had cofounded some 20 years earlier. Roksan achieved early success with Moghaddam’s first turntable design, the Xerxes, which is still in production, after many iterations, and is still highly regarded.

The Swiss know how to make high-quality, compact machines. They own the high-end automatic watch market, right? Every year, a Swiss manufacturer like Audemars Piguet brings out a new complication—movement—that contains even more parts, does more crazy computations, that never needs resetting for leap years, the orbit of Neptune, Easter, all that stuff. I own an Omega Speedmaster watch, and it doesn’t do any real tricks. It’s a NASA-approved chronograph, so I can time my steaks superbly to ensure they’re medium rare every time, but other than that, all it does is tell the time with great accuracy. I have seen this watch with the back cover removed, and there’s a whole world in there—gears, levers, springs—all manufactured with insane precision. Switzerland is the land of miniaturization.

Reviewers' Choice The NAP 350 is the third and final component of Naim Audio’s 300 series to be evaluated here on SoundStage! Ultra.

Naim has an illustrious history of amplifier manufacture, but the vast majority of its power amplifiers to date have been stereo designs. Perhaps the firm’s most famous mono power amplifier was the legendary NAP 135, which first emerged in 1984 and became established as a more powerful alternative to the stereo NAP 250. In active guise, a sextet of NAP 135s could be assembled into a magnificent “six-pack” active system to drive three-way speakers such as Naim’s cavernous DBL.

Reviewers' Choice Design and development

In 1962, when The Beatles were raising the roof at Liverpool’s Cavern Club, Hideo Matsushita founded Audio-Technica in a small apartment in Japan. His first product, the AT-1 phono cartridge, received a warm reception and was quickly followed by the AT-3 and AT-5 moving-magnet designs. By the 1970s, Audio-Technica was the biggest manufacturer of phono cartridges in the world. With the advent of digital audio and the CD, the firm diversified into headphones and microphones, fearing the impending decline of vinyl. While vinyl sales did indeed fall, the firm continued producing an array of cartridges to suit all budgets. The resurrection of vinyl from its 1990s nadir has enabled A-T to continue to innovate and to grow its cartridge-manufacturing operation.

Reviewers' Choice This wasn’t how a review process normally starts. I’d just received the Thales TTT-Compact II turntable for review and was rolling up my sleeves to dig right into this fascinating product. According to Wynn Wong, the Canadian distributor, the Thales ships to the dealer, and thus the customer, as a ready-to-go package, complete with their Simplicity II tonearm and—this is what threw me—the X-quisite Voro cartridge.

I have a sweet tooth when it comes to turntables, but I’m not stuck on one type of confection. I’m an equal-opportunity fetishist. I love turntables made from solid steel, real wood, MDF painted to look like wood. Piano lacquer, matte paint, or—gasp—clear acrylic.

Technology and design

The Naim NAC 332 is the second component in the new Naim 300 range to be reviewed on SoundStage! Ultra. The 300 series is only the fourth generation of Naim amplification to be launched since the firm’s inception in 1973. Priced at $10,999 (all prices in USD), the NAC 332 preamp sits in the middle of Naim’s hi-fi separates series, above the new 200-series NSC 222 streaming preamplifier ($8999) and below the existing NAC 552 preamplifier ($32,000), which will continue in production unchanged, save for switching to white front-panel illumination. In effect, the NAC 332 replaces both the discontinued NAC 282 and NAC 252 preamplifiers with a single unit. It’s all part of a simplification strategy that’s admirable, not least because the NAC 332 is priced only slightly above the NAC 282 (currently retailing at $8599) and below the recently discontinued NAC 252 ($12,599).

Reviewers' Choice I feel like I’ve been chasing this speaker around the world.

Back in 2022, I flew to Denmark for a tour of DALI’s headquarters and an in-depth introduction to the company’s new statement Kore loudspeaker. I was surprised to learn that DALI—an acronym for Danish Audiophile Loudspeaker Industries—is the second-largest manufacturer of speakers in the world. I was equally surprised by the depth of DALI’s investment in the infrastructure and technical expertise that went into the Kore project. While the folks at DALI were rather coy on the issue, they did hint that some of the Kore-specific technologies were likely to trickle down to future products . . .

Reviewers' Choice History, technology, and design

Last year, Naim Audio celebrated its 50th anniversary. It’s incredible to think that there have only been four iterations of Naim’s core model range during those 50 years. Put that in the context of mass-market brands that revamp their entire product line every year, and you’d think the R&D engineers in Salisbury spend most of their day playing croquet on the corporate lawn before retiring inside for a spot of tiffin! I have been behind the scenes, though, and the factory is a hive of activity. The place has a vibe reminiscent of Bletchley Park, where the Enigma code was cracked during WW2: a hodgepodge of buildings and a whole lot of boffins. Serious-looking types stare intently at advanced CAD workstations, while others bustle about in white or beige engineer’s coats, taking prototype next-generation audio hardware under cover into secret listening rooms.

It was a snap decision. Back in May, at the 2023 High End show in Munich, Germany, I found myself sitting in YG Acoustics’ room getting the cobwebs of a hangover blasted out of my skull by the Denver, Colorado, company’s new Ascent speakers. The room was populated by a bunch of young folks, all wearing YG Acoustics polo shirts, all extremely enthusiastic, all ready to talk about the company’s speakers, and all more than ready to take musical requests. It was a fun visit, and I was exceptionally keen to get in a pair of these new speakers for review. So I put a bug in the ear of CEO Matthew Webster, and followed up several times via email to make it so.
