Musical Fidelity's "Supercharger" concept is simple, which is perhaps why no one had thought of it before: If you love the sound of your low-powered amplifier but your speakers are insensitive, or you just need more loudness, you insert the high-power Supercharger amplifier between your low-powered amp and speakers. The Supercharger loads the small amplifier with an easy-to-drive 50 ohms, and, in theory, has so little sonic signature itself that it passes on the sonic signature of the small amp unchanged, but louder.
Some reviews take longer to gestate than others. But in the case of Cary's CD 306 SACD Professional Version SACD/CD player, it has taken me literally years to get this review into print. I had visited Cary's impressive facility in North Carolina just before Christmas 2005, when I'd been playing the high-resolution master files of some of my recordings at an event being promoted by Raleigh high-end dealer Audio Advice. Cary's head honcho, Dennis Had, had been playing me music on a system featuring his Silver Oak loudspeakers, with the front-end one of the first samples of the original CD 306, playing discs through the two-chassis Cary SLP 05 preamplifier that Art Dudley ended up reviewing in the September 2006 issue. "Now that's a product I'd like to review!" I enthused, looking inside the CD 306, and I drove back to Brooklyn with a review sample.
"Physical discs seem so 20th century!" That's how I ended my eNewsletter review of the Logitech (then Slim Devices) Squeezebox WiFi music server in April 2006, and it seems that increasing numbers of Stereophile readers agree with me. In our website poll of January 5, 2008, we asked, "Are you ready for an audiophile music server?" The response to that question was the highest we have experienced: 32% of respondents already listen to music via their computer networks, many using home-brewed solutions, and 44% intend to. We've published a lot of material on this subject in the last five years, and it seemed a good idea to sum it up in this article.
As Jason mentioned earlier, I gave 5 hour-long presentations at RMAF entitled "Hearing is Believing—Is Hi Rez Digital the Future of Audio?" To allow Showgoers to hear the differences between the hi-rez masters of my recordings and CD and MP3 versions, I used a system put together by HiFi+ editor Roy Gregory for his demonstrations of system tuningAyre A7-xe integrated amplifier, Avalon Evolution NP2.0 speakers (which I reviewed in July, Vertex AQ cables, Stillpoints rack and speaker stands, and Quantum QX4 "field generator"to which I added a MacBook running iTunes 8 driving a Wavelength Audio Cosecant USB DAC.
A close-up of the Wavelength Cosecant v3 DAC ($3500) that I used for my hi-rez dems. Using a single 6GM8/ECC86 dual-triode to drive the single-ended, transformer-coupled output, this is one of a very few USB-input DACs on the market that runs the USB link in "asynchronous" mode, whereby the DAC controls the flow of data from the computer and not vice versa, thus drastically reducing word-clock jitter when those data are fed to the DAC chip. I was impressed by its sound, playing 24-bit/88.2kHz files from my laptop, so I have asked for a review sample.
I was surprised not only by the ease to the sound of my hi-rez audio files played on the system in the Wavelength room, but also by the resolution. Surprised, because I am not naturally a tube guy, and not only is Gordon Rankin's gear tubed, it is unshamedly single-ended.
RMAF was my first chance to hear the new McIntosh MT10 turntable ($9500) that had starred in our 2008 CES blog. But after I had listened to vinyl on the McIntosh system for a whileand very good it sounded, tooRon Cornelius drew my attention to the MCD500 SACD/CD player ($6500) at the top left of the stack shown in the photograph.
Luxman and Vivid distributor Philip O'Hanlon, of On A Higher Note, always has a great selection of music at Shows, and RMAF was no exception. With a system based on Vivid B1 stand-mounted speakers ($13,500/pair) driven by a Luxman 30Wpc class-A integrated amplifier via Synergistic Research cables, the sound of an open-reel dub of a Reference Recordings Malcolm Arnold orchestral piece was distinguished by an enormous, stable soundstage, and excellent dynamics, with superb resolution of low-level orchestral detail. But I just can't get used to the speaker's alien-pod appearance.
I admit it. I have found YG Acoustics' hyperbolic promotional material off-putting. But having recently listened to the Colorado company's 4-way Anat Reference Professional speaker system in Wes Phillips' systemhe is reviewing it for our February 2009 issueI made a point of seeking the speaker out for a longer audition at RMAF.
