At some point within the last few years of his life, the late Ken Shindo designed an outboard phono preamplifiera decision perhaps made inevitable by his earlier decision to answer popular demand with line-only versions of the Aurieges and the more upmarket Vosne-Romanee preamps...
Of the hundreds of product reviews I have written over the years, it is perhaps those of power amplifiers that present the hardest task in defining their worth. This is not because power amps are unimportant. As I wrote in my review of the MBL Corona C15 monoblock, in June 2014, "it is the power amplifier that is responsible for determining the character of the system's sound, because it is the amplifier that must directly interface with the loudspeakers. The relationship between amplifier and loudspeaker is complex, and the nature of that relationship literally sets the tone of the sound quality." But because the amplifier's role is so fundamental, it can at first be difficult to determine a given amp's balance of virtues and failings. A paradox.
Late in the fall of 1982, Los Angeles turned ugly for me. I'd finished my work on Tron and despite the Academy Award nomination for Best Sound (which went to the mixing team, not the sound supervisor), it was obvious that nothing else was coming my way anytime soon. To earn a living, I had to reinvent myself.
So there I was in Las Vegas, at the 1983 Consumer Electronics Show, schlepping heavy bags filled with press kits, each containing an audio cassette of a dozen radio commercials for a car-stereo store that I'd voiced and produced, along with a résumé-bio and endorsements from clients.
Stereophile normally doesn't review audio systems. We review individual components. We've made an exception for the Bel Canto Black system because it deserves to be evaluated as such. It consists of three dense, almost identically sized cases of black-anodized aluminum. One, the ASC1 Asynchronous Stream Controller, is what in a conventional system would be called a "preamplifier." The other two, a pair of MPS1 Mono PowerStreams, would in a conventional system be called "monoblock power amplifiers."
For me, the highlights of any audio show are finding a room with great sound and visiting it often throughout the show, to relax and absorb a wide range of great music. At the NY Audio Show in April 2012 in New York City, it was the room occupied by the Valve Amplification Company. There, I fell in love with the sound coming through the Signature Mk IIa line-stage preamplifier, and remembered that while I'd heard many VAC products at audio shows over the past two decades, and had enjoyed the sound every time, I'd never had a VAC product in my house. I requested a review sample.
Google Bricasti and all that comes up are sites relating to Bricasti Design products. The name must be fancifulit sounds Italian, but cofounders Brian Zolner and Casey Dowdell most likely are not, and the company's headquarters are not in Milan or Turin but in Massachusetts.
While its name might be whimsical, nothing else about Bricasti is. As John Marks reported in his review of Bricasti's M1 DAC in the August 2011 issue, both founders previously worked at Lexicon: Dowdell as a DSP-software engineer, Zolner as international sales manager. Bricasti develops its products in conjunction with Aeyee Labs, formed by a group of ex-employees of Madrigal Audio Laboratories and based in New Haven, Connecticut.
In 1978, after enduring four or five years of wretched music made by men with long hair and beards and tendencies toward eonic guitar solos, I suddenly discovered that the only music worth hearing was made by clean-shaven men of limited musical proficiency. I embraced the Clash, the Pistols, the New York Dolls, the Ramones, and the Buzzcocks. I cut my hair and gave away some of my old records. I even threw out my copy of Jethro Tull's A Passion Playwhich, now that I think about it, wasn't that bad an idea.
Then I woke up and remembered: I'd left the baby in the bathwater.
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.
I've seen how most manufacturers work. They start out by making products they believe inproducts consumers are likely to love. But after a while they begin listening to their dealers and distributors and marketing consultants, most of whom are inclined to say things like: "You need to make a six-figure turntable, to compete with all the other six-figure turntables." "You need to make a $1500 amplifier, to fill that price gap in your product line." "You need to make a small, stand-mounted loudspeaker."
Several seconds after I began listening to it, I knew that Theta Digital's Prometheus monoblock amplifier ($12,000/pair) was different from other amplifiers. The violins and brass were more dynamic, and had more pace. The orchestra sounded more three-dimensional, depicted in relief by a degree of hall ambience I hadn't heard when I played the same recording through my reference solid-state stereo amplifier, a Mark Levinson No.334.
Powerful, massive, and expensive, Revel's Ultima Rhythm2 subwoofer ($10,000) swept me off my feet when I first saw it in Harman International's suite at the 2013 Consumer Electronics Show. It outsizes, by 49 lbs and 2.6 cubic feet, Revel's previous flagship model, the Ultima Sub30, which I reviewed in the November 2004 issue. Its specs read like no other sub's: 196 lbs; 18" cast-frame woofer; dual 4" voice-coils; 4kW peak power from twin internal amplifiers that generate 1kW RMS; 115dB peak acoustic output; a fully configurable, high-resolution, 10-band parametric equalizer (PEQ); an internal crossover with high- and low-pass outputs; and PC-based setup via USB. The Rhythm2's patent-pending design is said to let just enough air move in and out of the cabinet to prevent any distortion-inducing pressure due to heating of the voice-coils. And its veneer, shape, beveled top edges, and bottom plinth exude the quality found in Revel's top-of-the-line floorstanding speaker, the Ultima Salon2, with which I was familiar.
Do you travel? Commute, perhaps? Just like to listen to music privately around the house? No matterthe Astell&Kern AK240 is the luxury choice in high-resolution portable music players (footnote 1). It even comes with a lovely leather case that beautifully cradles its angular beauty. The AK240 can play all of your PCM files, up to a resolution of 24-bit/192kHz, as well as DXD and single- and double-rate DSD, natively, and can do so from its internal storage, from a microSD card, or from your computer via WiFi or a wired connection. It can also function as a DAC or USB-to-TosLink converter. I'm not so sure there's much left wanting.
There may have been a time when vacuum tubes and microprocessors seemed strange bedfellows. But nowadaysgiven the countless digital processors with tubed output stages, and an even greater number of tubed amps and preamps whose insides are crawling with the latest solid-state deviceswe're more or less used to the idea. Here as elsewhere, hybrids are no big deal.
The experience left me doubting my ears. After I'd performed all the measurements of Ayre Acoustics' KX-R preamplifier ($18,500) to accompany Wes Phillips's review in our November 2008 issue, I spent a weekend listening to it. To my astonishment, the sound of my system with a Transporter D/A processor feeding the preamplifier was better than when the DAC fed the power amplifier directly. Through the KX-R, images sounded more tangible, and the sound was better focused, despite the signal's having been passed through not just another set of interconnects but also through the preamp's input and output socketry, switches, a volume control, printed circuit-board traces, and active and passive parts. Logically, you'd think that having nothing in the signal path would have less of a degrading effect than so many somethings. But no, that was not what I heard, much as I would have preferred otherwise.
Can a power-supply upgrade produce audible sonic benefits? If you've upgraded the power supply of a phono preamplifier, you probably don't need to be convinced that it does, and those usually cost only a small percentage of the price of the model they power. But to add Simaudio's Moon Evolution 820S power supply ($8000) to the Moon Evolution 650D DACCD transport ($9000), which I reviewed in the November 2011 issue, almost doubles the latter's costthough the 820S can be used to simultaneously power two Moon Evolution components, like the 750D DAC ($14,000), 740P preamplifier ($9500), and 610LP ($7500) and 810LP phono preamplifier ($13,000).
