Audacious Audio

I jumped at the chance to review T+A's $47,900/pair Solitaire S 530 loudspeaker for a few reasons. First, because T+A is a well-established company with an approach I like and respect: They make hi-fi equipment of the highest quality but with prices that, though substantial, are in line with their technology and execution. Their stuff is very handsome with impressive industrial design, but T+A doesn't do audio jewelry. What's more, though T+A is aggressive in R&D—their "Company" webpage says, "Actually, we're scientists ..."—but they are selective in the use of new technology. The third reason I was interested in reviewing a product from T+A is that their prices and technical level place them in a market segment I know well.

What I didn't know until recently is that T+A makes loudspeakers, and they're quite different from the loudspeakers other companies make. I only learned this when I started hearing about the S 530 and its larger sibling, the S 540, from friends—friends whose ears I trust.

Based in Bulgaria, European audio company Thrax has been active since 2009. Their ingenious and varied design approaches seen over several product lines have continued to intrigue me with their conceptual originality, innate musicality, and imaginative use of a broad spectrum of technologies. Their products range from valve (tube) amplification to digital audio and, more recently, loudspeakers . . . The range of distinctive high-end electronics has continued to expand to include a loudspeaker, the standmount Lyra, now joined by the smaller Siren ($13,600/pair), also a standmount and the subject of this Stereophile review.

Edmund (Ed) Manfred Meitner's name and reputation have long been synonymous with pioneering achievements in the fields of digital audio, especially DSD. In 1971, after designing the first fully automated studio console, Ed identified what he calls "the jitter problem." He worked with Sony and Philips to help create and refine SACD and subsequently designed the first complete six-channel DSD playback system for home use.

In 1998, while developing the eight-channel A/D and D/A DSD converters still used to create most SACDs, Ed founded EMM Labs and became head of design, with the goal of bringing DSD to the consumer realm...

Less widely discussed are Ed's amplifier circuit designs, which are the heart of the EMM Labs MTRX and MTRS amplifiers he designed collaboratively with Mariusz Pawlicki, EMM manager of R&D, and the late Zenon "Zanny" Muzyka.

When standalone digital/analog processors made an appearance a quarter-century ago, they were limited to the CD medium's 16 bits of resolution—at best. These days, almost every DAC can process at least 24 bits, and many models offer between 20 and 21 bits of real-world resolution. Modern models from Benchmark, dCS, , Merging, Mola Mola, Okto, and Weiss illustrate not just the skill of the circuit designer but also that of the engineer who laid out the printed circuit board.

One of the first digital processors I encountered that offered 21 bits of resolution was the Weiss DAC202, which Erick Lichte reviewed in January 2012. Subsequent processors from this Swiss company have consistently performed well, not just on the test bench but also in the listening room.

Back in August, I received an email from Editor Jim Austin. Subject line: "Want to do a big review?" He had my attention. Jim wrote that he had visited Bowers & Wilkins parent company Masimo Consumer in Carlsbad, California, for a demo of the brand-new B&W 801 D4 Signature and 805 D4 Signature loudspeakers. (That visit was chronicled by Jim in the September 2023 Industry Update section.) B&W had offered Stereophile the first US review of both products—look for John Atkinson's review of the 805 D4 Signature in the coming months—and Jim thought the big 801s would be "right up my alley."

Indeed! The voice of my full-range system in the living room is a pair of B&W 808 speakers, ca late 1980s. The smaller-scale system at our house upstate features a pair of B&W 805 D2s. So, outside of my mastering studio, most of the music I listen to is through Bowers & Wilkins speakers. I am accustomed to and enjoy B&W sound and styling.

Wilson Audio's new Sasha V loudspeaker (that's "V" as in victory, not "five") extends the line that began in 2009 with the debut of the Sasha 1 model. The installation manual includes a page titled "Sasha Evolution," with elegant line drawings of the various versions of the Sasha loudspeaker—now four—which were preceded by the two-box WATT/Puppy combo, which dates from 1989. The Wilson Audio Specialties Sasha V ($48,900/pair) replaces the prior Sasha model, the Sasha DAW, in the Wilson lineup.

The hefty, floorstanding Sasha V maintains a close family resemblance. The new Sasha's width and height are almost identical, logging 14½" and 45 1/16", respectively. The cabinets gain an inch in depth and now measure 23 15/16". The cabinets' subtle beveling is slightly different; probably only recent Sasha owners would notice. Extra thickness in the cabinets adds 9lb for a total of 245lb per speaker.

When Jim Austin offered the Plinius Reference A-150 stereo amplifier ($14,995) for review, it felt like a welcome blast from the past. Plinius has, lately, maintained a low profile in the US, likely due to several changes in US distributorship...Under the auspices of Ralph Abramo and California-based Plinius Audio Sales and Repair, Plinius's US profile seems to be rising again.
