MSB’s Analog DAC

I still remember how much I enjoyed the sound of hi-rez files decoded by MSB’s DAC, when it resided briefly in my system after I performed the measurements to accompany Jon Iverson’s review last October. So MSB’s room at the Atrium was one of my first stops. A pair of YG Anat 3 Signature speakers with Billet-Core midrange units and woofers was being driven by MSB’s S200 200Wpc, zero-feedback, class-A amplifier ($17,995) and source was the Platinum Data CD IV transport. However, the bits were being converted to analog not with the Diamond DAC but MSB’s new “entry-level” Analog DAC ($6995 with standard outboard power supply, $9990 with upgraded Analog Power Supply, which shares the same form factor and is shown sitting underneath the DAC), which is said to offer “a generous percentage of MSB’s technology.”

Magnepan: “Made in America, Sold in China”

That was the message on the poster in Magnepan’s room. Wendell Diller, celebrating his 40th anniversary with the Minnesota company, explained that Magneplanar speakers use 90% US-sourced parts and demmed the new, 48”-tall, two-way-plus-woofer Super MMG ($1199/pair with one bass panel, $1750 /pair with two) with an Ati amplifier and a Theta Casablanca preamplifier. The sound on a varied program was sweet, almost full-range. I couldn’t see the bass panels; Wendell pointed to the end tables on the outside edges of the speakers. To increase the Spouse Acceptance Factor, he had disguised the planar woofers.

The Tweak Studio Presents Elac

Chicago retailer Tweak Studio has been a fixture at the 2013 shows, and proprietor Arnold Martinez was demming a system featuring Elac 249 Black Edition speakers ($8000/pair) driven by a Burmester 911 amplifier ($31,000), Esoteric C-03X preamplifier, Burmester A/D phono preamplifier ($26,500), and Music Hall MMF-11 turntable fitted with a Goldring Legacy cartridge ($600). Wiring was all WireWorld Platinum series and the racks was a Stillpoints. The L-shaped lobby-level room had problematic acoustics, which Martinez had addressed by firing the Elac speakers, with their AMT tweeter and distinctive faceted lower-frequency drivers, across a diagonal, A dub version of Bob Marley’s “Waiting In Vain,” played from LP, was musically convincing.

Dynaudio’s Evidence Platinum

Because the show was too big for one person to see it all, Jason Serinus and I split our responsibilities: he would cover the Hilton and I would cover the Atrium Hotel, plus some of the rooms at the Hilton that he failed to visit. The first room I visited at the Atrium was the large ballroom on the mezzanine featuring Dynaudio’s new Evidence Platinum loudspeaker ($85,000/pair). Did I say “large”? I meant to write “enormous”! The room was way too big, but with acoustic treatment from Vicoustic, the system produced much better sound than I was anticipating. I listened to Jeff Buckley’s “Lilac Wine” (from Grace), Bill Evans in hi-rez, and a live Dutch recording from David Crosby with an electric band performing a song called “Morrison”; with all three recordings, the imaging was solid and tangible, the low frequencies rich but well-defined, and the midrange uncolored.

Dean Peer Rocks

T.H.E. Show featured a full program of live music all weekend. As they have done at many recent shows, Cardas Audio sponsored concerts by electric bassist Dean Peer, accompanied by percussionist Bret Mann, poolside at the Atrium Hotel. Dean fed his bass through a variety of effects pedals to produce a wide variety of sounds, but the music came from his hands. In vain did I peer (ha!) at those hands to see how he was producing those chords of harmonics and the underlying rhythmic pulse while floating melodies on top. The man is a monster!

Turntable Set-Up Demystified

I have to hand it to Stereophile’s Michael Fremer (right), who also edits AnalogPlanet.com. The man has large attachments! I find cartridge set-up intimidating and I don’t even attempt it until I am in the “zone.” But Mikey does it in public with a video camera amplifying his every motion. At one point in one of his two packed 90-minute seminars at T.H.E. Show, he even picked up the VPI turntable he was working, provided by David Weinhart (left), founder/owner of Ambrosia Audio & Video and owner of Los Angeles retailer Weinhart Design, Inc., to rotate it with the stylus still resting in the groove so the video camera could get a better view! As I said, large attachments.

Velodyne DF-661 loudspeaker

Silicon Valley–based Velodyne was founded in 1983 to develop a range of subwoofers that used servo-control to reduce non-linear distortion to vanishingly small levels. They succeeded in this goal to the extent that Velodyne is now perhaps the best-known subwoofer company in the US, currently employing 65 people. At the 1994 Winter CES, Velodyne launched the subject of this review: the DF-661 ($1800–$2600/pair), their first full-range loudspeaker (the "DF" stands for "Distortion-Free").

The three-way DF-661 was designed from the ground up to continue the Velodyne tradition of ultra-low distortion. "We had developed the technology and resources to attack distortion elsewhere in the audio chain," wrote company President David Hall, "and started with the premise that, by definition...distortion in loudspeakers is wrong." (His italics.) "We went to the laboratory for a solution, with the living room as the ultimate goal." Velodyne calls this attention to technological detail "The Silicon Valley approach to sound."

Just How "Absolute" Is Recorded Sound?

John Atkinson at the 2012 Rocky Mountain Audio Fest

Since I gave this presentation at the Rocky Mountain Audio Fest in October 2012, based on one of the topics in my Richard C. Heyser Memorial Lecture and mentioned in my March 2013 "As We See It," I have repeated it at Music Matters evenings at Definitive Audio in Seattle and Listen-Up in Denver, and at audiophile society meetings in Minneapolis, California's Central Coast, and Connecticut. I will be repeating the presentation at a Music Matters event at Georgia retailer Audio Alternative, Wednesday April 24, at 6pm, at T.H.E. Show Newport Beach, at 12 noon, May 31, and at The Audiophile Society in Brooklyn, NY on June 22.
