Audacious Audio

As we approach the end of the 21st century's "oughts" decade, many feel that playing music from a discrete physical medium is positively 20th century. Much of my own music enjoyment now comes from computer files, often high-resolution, streamed to my high-end rig via a Logitech Transporter or Bel Canto USB Link 24/96. It is perhaps a paradox, therefore, that high-end audio companies are still devoting so much effort to developing expensive, state-of-the-art disc players. In April I very favorably reviewed Meridian's superb 808i.2 CD player–preamplifier, which costs $16,995 as reviewed, and Michael Fremer is about to review the ultimate Scarlatti SACD playback system from another English company, dCS. The $80,000 price tag of the Scarlatti makes the subject of my review this month, the Boulder 1021, seem relatively affordable at $24,000.

Can an $18,000 power amplifier be a bargain?

Can an $18,000 wristwatch?

For several decades—from well before I toured the Boulder factory in 2016—I've wanted to get a handle on the best sound the now–41-year-old company can offer. Multiple listening sessions at shows had more than hinted at excellence. But neither my time in Boulder's large, dedicated music room, which was intentionally dry, nor exposure at various hi-fi shows left me convinced that I'd heard Boulder's full potential.

My first opportunity for an in-home audition came in 2021, when I reviewed the 866 stereo integrated amplifier ($17,500 with DAC, $16,000 without). But that entry-level (by Boulder standards) product, which Senior Engineer Jameson Ludlam said was released to build brand awareness and expand the company's reach by offering "a more accessible product that provides the features we think many people are looking for with the performance they have come to expect from Boulder," only provided a peek at the excellence I expected Boulder to achieve.

So when a last-minute review cancellation opened space to review the just-released Boulder 1151 mono power amplifier ($47,000/pair), I thought, "At last!"

Why bother with three phono preamps most of us can't afford? For the same reason the enthusiast automobile magazines cover the newest Ferraris and Lamborghinis: just reading about them is fun.

Founded in 1984, Boulder Amplifiers is a conservative audio company that goes quietly about its business, choosing not to call attention to itself with marketing flash or acronym-laden features. Change comes slowly to such companies, which is why the just-retired 2010 preamplifier enjoyed a 17-year run.

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.

The "Bowers" in the name of British manufacturer Bowers & Wilkins (B&W) refers to founder John Bowers, whom I got to know fairly well before he passed in 1987. In recent years, I've reviewed two Bowers & Wilkins loudspeakers: the 705 Signature two-way standmount in the December 2020 issue and the Diamond Series 804 D4 three-way floorstander in the January 2022 issue. More recently, Tom Fine reviewed the three-way, floor-standing Signature Series 801 D4 in March 2024.

Currently there are two models in the Signature Series, which was launched in 2023 to pay tribute to the company's groundbreaking John Bowers Silver Signature from the early 1990s: the 801 D4 and the subject of this review, the two-way 805 D4 standmount, which B&W describes as its "highest performance standmount ever."
