Ever since I raved about Krell's K-300i integrated amplifier after it was released in early 2019, I've wanted to review other Krell products. After spending more than a year and a half (since its prerelease announcement) awaiting the opportunity to review Krell's new flagship mono power amplifier, the KMA-i800 ($73,000/pair), the time has come. Both Krell models utilize the company's proprietary iBias technology, albeit in different iterations, and both were designed by longtime Krell engineer Dave Goodman.

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.

One of the finest chamber music performances I have ever attended took place this past August under far from ideal circumstances. The venue was one-month-old Field Hall in Port Angeles, Washington, a city of fewer than 20,000 people known more for its port and proximity to the Olympic National Forest than for its rich culture. Perhaps that reputation will soon change, because the performers in the concluding concert of the Music on the Strait chamber music festival included its two local founders, violinist James Garlick of the Minnesota Orchestra and violist Richard O'Neill, the newest member of the Takács String Quartet. These excellent musicians, who have been friends since high school, were joined by the superb pianist Jeremy Denk and cellist Ani Aznavoorian. These are world-class musicians who attract eager audiences to New York's 92nd Street Y and Carnegie Hall, London's Wigmore Hall, and other prestigious venues. . .

What was true for that live performance in Field Hall is also true for performances reproduced on audio systems: A system can be less than technically perfect yet still transmit with eloquence every iota of care and feeling that artists and engineers put into recordings. Perfection is not an essential component of musical truth. Inspiration is.

Lest readers think this preamble is intended to suggest some shortcoming in the component under review, the Accuphase A-300 monophonic power amplifier ($51,900/pair), let me reassure you at the outset: Time and again, the A-300, like Jeremy Denk's artistry, inspired a state of wonder. The more I listened to the A-300 monoblocks, the more I wanted to listen. In my too-busy life, every occasion for listening was an occasion indeed, a special event.

I should have trusted my ears. When I first encountered Infigo (pronounced In-FEE'-go) electronics, paired with Alta Audio's Adam loudspeaker, at T.H.E. Show 2022 in Long Beach, California, I wrote, "Timbres were beautiful on bass and high-pitched percussion. The chimes and vibes sounded special and clean, colors were plentiful, and deep bass was all of one piece." Nor was I exaggerating. In that system, Infigo's Method 3 monoblocks ($55,000/pair) pleased my ears as much as their blue-illumined interiors delighted my eyes.

Rather quickly, Editor Jim Austin suggested I review the Method 3. Perhaps he'd already been tipped off by Ken Micallef's praise when he first encountered Infigo in November 2021 at the Capital Audio Fest, and by the ensuing buzz.
