Understanding Loudspeakers

My loudspeaker seminar on Saturday featured Dick Diamond of YG Acoustics (to the left in Jason's photo), John MacDonald of Audience (far right) and Bill Dudleston of Legacy (immediate right with hand raised). The first half of the session featured each panelist discussing what his goals were as a loudspeaker manufacturer, what technical parameters he felt most correlates with good sound, how he balanced all the various aspects of performance to get a good balance at a specific price, and where he felt there was the greatest room for continued improvement in speaker performance. The second half of the seminar consisted of a Q&A session and there was a lively discussion, including mention of the fact that all three companies featured on the panel continue to manufacture their speakers in the US.

Michael Fremer

<I>Stereophile</I> senior editor Michael Fremer hosted two turntable set-up seminars at Axpona, explaining how to optimally install and set-up a phono cartridge and tonearm for lowest distortion and best sound. He did a great job of demystifying an arcane subject; for those who couldn't attend Axpona, you can see an expanded version of the seminar on his DVD <I>21st Century Vinyl</I>, available from <A HREF="http://ssl.blueearth.net/primedia/home.php?cat=3">this website</A>.

Mark Waldrep

In addition to his enormously impressive hi-rez surround-sound dem mentioned earlier in this report, Mark Waldrep of AIX Records and iTrax.com gave a well-attended seminar on all three Show days explaining how a computer can be used as a valid source in a high-end audio system and demystifying HD music.

The Recording Angel

Back in the last century, I mused in this space about the essential difference between recorded sound and the real thing. I had been walking to dinner with friends when I heard the unmistakable sound of live music coming from a window. But here was the kicker: rather than the instruments being of the audiophile-approved acoustic variety, they were two amplified electric guitars. Their sounds were being reproduced by loudspeakers, yet it was unambiguously obvious that it was not a recording being played through those loudspeakers, but real instruments.

Bob Carver: Carving a Name For Himself

Although it was Thomas Edison who set the tone for technological development in the 20th century, with his intellectual sweatshop in New Jersey, it is the lone inventor who has always had a special place in the heart of the American public. Since the days of Samuel Colt, Eli Whitney, and Nikola Tesla, fortune and fame have awaited the genius tinkerer who emerges from his back yard with a better mousetrap, cotton gin, etc., etc.

ASUS Xonar Essence ST/STX soundcards

With all the current fuss about getting audio data from a computer to a standalone D/A processor via S/PDIF, USB, FireWire, WiFi, or Ethernet (footnote 1), it has been overlooked that the oldest way to get audio from a PC is to use a high-performance soundcard plugged into the host machine's motherboard. I remember how excited I was when I installed a Sound Blaster Pro 16 board in the 486-based Dell running Windows 3.1 that I was using in the early Clinton era, plugged its analog output into my high-end rig, and played back 16-bit/44.1kHz files.

Wilson's Polaris Center-Channel

I know, center-channel speakers are the bailiwick of our sister magazine <I>Home Theater</I>. But as Wilson Audio Specialties' Peter McGrath told me when he explained the speaker's technology to me in the Utah company's suite at the Mirage, two Polarises work magically as a stereo pair. (Unfortunately, the speaker was only being shown, not demonstrated.)

Electric Odeon Elektra

I had gone into the Koetsu USA room at the Venetian to catch up on the latest developments to the Italian Blacknote DSS30 media server, which I hope to be reviewing later in the year. But I was very taken by the sound of the three-way Odeon Elektra loudspeakers ($19,100/pair), which, driven either by the DSS30,a Goldennote Stibbert CD player, or a Montegiro LP player, via a Goldennote 75Wpc, solid-state integrated amplifier, didn't sound <I>at all</I> like what I expect from horn speakers. Strings had a natural sheen, brass winds a natural "blattiness." Whether solo voice, classical orchestral, or solo piano (a high-rez Beethoven Sonata from 2L), the sound was uncolored, unstrained, and enjoyable.

Esoteric RZ-1 Music System

Havng recently used Esoteric's four-box SACD playback system, with its dual-mono DACs and the ultra-high-precision Rubidium Clock unit, I checked out what the Japanese company was displaying in the rooms they were sharing with cable manufacturer Synergistic Research. My eye was caught by this beautifully styled one-box SACD player/DAC/100Wpc amplifier. The RZ-1 is scheduled to sell for $6000 and as well as using one of Esoteric's highly regarded SACD/CD transport mechanisms, it has both 192kHz-capable S/PDIF and 24/96-capable USB digital inputs and—significantly for the way the audio market is going—a phono preamplifier. The 32-bit D/A section uses an AKM AK4392 chip and offers both a conventional reconstruction filter, one that resembles Meridian's minimum-phase "apodizing" filter.
