Wavelength's Cosecant 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.


Listening to Hi-Rez

As Jason mentioned">http://blog.stereophile.com/rmaf2008/101208house/">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 tuning—Ayre A7-xe integrated amplifier, Avalon Evolution NP2.0 speakers (which I reviewed">http://www.stereophile.com/floorloudspeakers/708ava/">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.


Big Boy Does Good

After a short visit to the Daedalus room, during which time Peigen changed speakers and cables, I returned to hear the F200's big daddy, the F300 ($14,900/pair). This is a 3-way, 4-driver vented box, with a rear-firing supertweeter, Air Motion Transformer tweeter, and copper shorting ring on the woofer to facilitate tighter bass. Frequency range is 24Hz–40kHz, sensitivity 89dB, and weight 158 lbs each. The speaker comes in two parts, so that the mid-and high-range unit can be used separately as a center channel with an impressive frequency range of 40Hz–40kHz. Associated components were the same as with the F200.


Tell It Like It Is

As I walked into the E.A.R./Marten room, Nat King Cole's voice sounded as beautiful as I have ever heard it reproduced. Through the modest-looking Marten FormFloor speakers ($6500/pair) and Marten FormSub ($4500), Reference Recordings' triumphant version of Rachmaninoff's Symphonic Dances was so thrillingly full and colorful that I could not hide my amazement. On Dialoghi, a demonstration-quality CD from Bob Attiyeh of Yarlung Records that Robert Levi of the Los Angeles Audio Society urged me to play, the sound of Elinor Frey' cello was as warm and beautiful as anyone would ever want it to be. I was in love.


Making Fine Music

Lou Hinkley's Daedalus Audio teamed up with an old friend, Art Audio/Gill Audio, and a new friend, Manley Labs. Showcasing the Daedalus Audio Ulysses loudspeaker ($10,950/pair), now boasting new improved internal wire, the system's dark presentation was very well delineated, with impressively three-dimensional sound. The midrange was especially mellow and inviting.


RMAF'S Present Success and Future Plans

As John Atkinson (right) and I were saying our goodbyes until the 2009 CES in Las Vegas, RMAF co-directors Al Stiefel and Marjorie Baumert were compiling attendance stats for this year's show. Although the fact that there were far more rooms this year, with exhibits spread over two hotels, left some exhibitors thinking that attendance was down, attendance was actually up just over 7%. Almost 3500 people attended this year's RMAF. The Sunday walk-ins were 407—almost 150 over last year.


Daedalus Audio Ulysses

More beautiful woodwork was found in the Daedalus Audio suite. The Ulysses ($10,950/pair; add $500 for matching plinths) is Daedalus Audio's top-of-the-line speaker. It uses a 1" Eton dome tweeter, two 5" custom-modified Fostex midrange units, and two 8" proprietary woofers, and has a rated sensitivity of 97dB.
