The Daniel Hertz M1

Stephen Mejias Apr 16, 2011

The Daniel Hertz M1 ($100,000/pair), designed by Mark Levinson (the man), uses a high-frequency horn, a 12” mid-woofer, and an 18” woofer. The stainless steel frame surrounding the horn is said to optimize waveform termination and imaging quality, while those frames surrounding the woofers are used to increase the rigidity of the drivers. The speaker is divided internally into two sections: One section for the horn and 12” driver, damped using sheep’s wool for its high mass and absorptive properties, and one section with two tuned ports for the 18” driver.

As seen here, the M1 is designed to be powered by four Telikos M5 Mono Reference amplifiers ($8000 each): Each channel uses one M5 switched to frequencies above 80Hz and one M5 switched to frequencies below 80Hz. Also in the system was a Telikos M6 preamp ($10,000). The source was a $400 laptop running WAV files from iTunes.

Interesting story: Daniel Hertz (the company) takes its name from the two sides of Mark Levinson’s family. Daniel Levinson was Mark’s father, while Heinrich Hertz (1857-1894), a German physicist and the first to demonstrate the existence of electromagnetic waves, was Mark’s great uncle on his mother’s side.

The YG Acoustics Anat III Signature

Stephen Mejias Apr 16, 2011

The YG Acoustics Anat III Signature ($119,000/pair) employs a new circuit in its main module which enables the speaker to play louder while minimizing midrange distortion. Though the Anat maintains its rated sensitivity of 89dB, its impedance is more even, which should make the speaker easier to drive. Completing the system were a Veloce preamp, Krell 402 amplifier, dCS Scarlatti system, and Kubala Sosna Elation cables.

Alright. As some graceful piano came slowly tinkling into the room, I was immediately struck by the system’s combination of scale and delicacy. And when the first voice came in, it was one of those holy shit moments. And when the second voice came in, it was another one of those holy shit moments. And when the two voices came together, all I could do was sit there and grin like a dummy, in awe of the texture and tone and exquisite delineation of images. And then the percussion&#151fast and clean and authoritative. It added up to a compelling complete performance, just as sonically impressive as it was emotionally involving.

I heard myself thinking wild thoughts: It’s incredible that reproduced music can sound this good…. Sitting there listening to Herbie Hancock’s The Imagine Project, I was having the same sort of reaction as when walking the halls of a museum or strolling down 34th Street between Fifth and Sixth Avenues, looking up at the Empire State Building: I’m just sort of amazed that humans can create such beauty.

Miles and Miles of Tweaks

Stephen Mejias Apr 16, 2011

Well, not really miles, but definitely a lot. Feet and cones and spikes and pucks and all sorts of fun stuff. I kinda just wanted to run as fast as I could and fling myself right up onto this table to swim with all of these little goodies. But I managed to restrain myself.

DaVinci USB DAC Does 384kHz

John Atkinson Apr 16, 2011

"It's fitting for the world premier of the Da Vinci 384k DAC to happen on the first day of Axpona," explained Light Harmonic's Larry Ho, "as today is Leonardo da Vinci's birthday." 384k? Yes, the Da Vinci DAC ($11,999 regular price, $8999 Axpona price [NOTE: The actual retail price ended up at $20k-ed.]) will operate at sample rates up to 384kHz. At the show, in a system featuring Wilson Sophia 3 speakers driven by Pass Labs amplification, a 2L recording of Ole Bull's violin concerto, sourced from a Mac 2-modded Mac mini running Pure Music and recorded with a 352.8kHz sample rate, according to the DAC's front panel display, offered up some of the sweetest-sounding, natural violin sound and the most solid stereo imaging I have experienced from a classical recording. The 384k DAC uses the USB2.0 protocol and functions on a Mac without a driver having to be installed.

Sutherland's Phono Block

John Atkinson Apr 16, 2011

"I made this for myself," explained the genial Ron Sutherland, as he showed me the interior of his new monophonic phono preamplifier ($9800/pair). The power supply on the right, which uses both choke and RC smoothing, feeds DC to the active circuitry on the left via a ribbon cable running in a channel machined in the front panel. Plug-in daughterboards are used to change loading and gain and three chassis grounding options allow for the lowest noisefloor: floating, grounded directly, and grounded via a 50 ohm resistor. Ron has used 1/8"-thick circuit boards to lower dielectric effects. There are two outputs to allow a mono cartridge to to be fed to both left and right inputs of the phono preamplifier.

Bob's Devices

John Atkinson Apr 16, 2011

"A North Carolina firm called Bob's Devices has joined my list of favorite phono step-up suppliers," wrote Art Dudley in June 2010. There in the Analog Ballroom at Axpona was Bob Sattin himself, showing off his range of affordable step-ups, using selected new and vintage transformers from manufacturers like CineMag, Sowter, and Altec.

Dean Peer, Musician

John Atkinson Apr 16, 2011

Electric bassist Dean Peer's concerts with drummer Bret Mann at the Montreal Show two weeks ago had been a highlight for me of that Show. At the Atlanta Show, Dean Peer was scheduled to take part in a jam session Saturday night, but Friday and Saturday afternoon, he gave a 60-minute talk on how he approaches playing the bass, making recordings, and how a musician and composer became involved in the world of audiophiles. He also played some of his compositions, including a favorite of mine from his first album Ucross, which was released exactly 20 years ago. Can't beat that live music!

Michael Fremer Explains Turntable Set-Up

John Atkinson Apr 16, 2011

An enthusiastic crowd turned up on the first morning of the Show to catch Michael Fremer's workshop on how to optimally set-up a turntable. With the help of close-up video, Michael used a Spiral Groove turntable and arm, and Lyra cartridge to show how to optimize headshell offset, overhang, antiskating, VTA, azimuth, and other analog mysteries. The session is being repeated Saturday at 11:30am in the Goldmine seminar room.

Audio Show Porn

John Atkinson Apr 16, 2011

While making my way to the Goldmine seminar room at Axpona, to catch Michael Fremer's turntable set-up talk, I came across pianist John Yurick playing some smooth jazz improvisations to a background of a Lamborghini and Aston Martin that happened to be parked in front of the Stereophile booth.

Record Store Day at Criminal Records!

Stephen Mejias Apr 15, 2011

Hey, as I type this, it’s 2am, which means it’s officially Record Store Day. Woo! Earlier in the week, I was feeling a bit bummed about not being able to participate in the festivities. Since I’d be covering Axpona, I figured there’d be no way that I’d get out of the hotel and down to a record shop. Don’t ask me why, but after 33 years of life, I continue to rob myself of opportunities, enforcing upon myself limitations that need not exist. It’s as if I’m still punishing myself for having been born. What is up with that? I don’t know. Good thing I’m getting soft in my old age, succumbing to peer pressure with much more enthusiasm than when I was a kid. A friend here at the show convinced me that I’d be out of my mind to pass up an opportunity to get a behind-the-scenes look at one of the country’s greatest independent record stores. So, at around 5pm this evening, he and I snuck out of the show and made the quick trip to Criminal Records in the colorful, entertaining Little Five Points section of Atlanta.
