Teresonic Speakers Play Loud

One of my last stops at THE Show at the Flamingo was the Teresonic room, where Mike Zivkovic demmed his 6'-tall single-driver Ingenium Silver Edition speaker using his own single-ended 2A3 tube amplifier. According to Mike, the amp uses interstage and output transformers from Lundahl and "there is not a capacitor in the circuit."

Epos Aims High With the Encore 50

Since the ES14 from the mid-1980s, speakers from the English Epos company have been renowned for their midrange magic, not for ultimate dynamics. But Mike Creek, Epos's owner, is aiming for both with the Encore 50, which made its debut at CES. This three-way floorstander, priced at $9995/pair, uses two port-loaded 9" woofers with Kevlar/carbon-fiber/pulp-composite cones, in a large cabinet to achieve a high 90dB sensitivity, while the metal-dome tweeter uses an injected-molded roll surround to give high excursion. The midrange is fed by a tapped autotransformer to allow adjustment to a tight tolerance in production.

Battery-Powered Tube Preamp from Siltech

Siltech's Edwin van der Kley handed me his new preamp. There were no wires attached, but the four tubes were glowing. "It's battery-powered, and I could use a low 25V voltage rail for the tubes because they are ECC86 dual-triodes, which were developed for car-audio and microphone use." Edwin went to explain that as this tube uses a 6.3V heater, he could run the heaters of the four tubes in series from the same 25V supply. It also offers very low 1/f noise for a small-signal tube, he told me. Siltech has a plentiful supply of the tubes and the preamp wil sell for $28,000.

Audio Research class-D Integrated

<A HREF="http://blog.stereophile.com/ces2010/audio_researchs_magnepan_amplifier/… in this report</A>, Brian Damkroger writes about the new Audio Research DS-450 class-D power amplifier. However, I was more taken by the Minnesotan company's $5995 DSI200 integrated amplifier, which offers 200Wpc into 8 ohms, compared with the larger amplifier's 410W, and had its top off. (This is Las Vegas, after all.) The 93%-efficient class-D outputstage was developed in-house and is coupled with a hefty linear power supply.

Trial By Stereophile

Most of the time at CES, <I>Stereophile</I>'s writers prowl the corridors in solitary fashion. But occasionally we find ourselves in the same room at the same time, which was the case in the Blue Smoke suite at the
Mirage, where we had gathered to check out the company's new server that Jon Iverson blogs about <A HREF="http://blog.stereophile.com/ces2010/blue_smoke_black_box_music_server/"… in this report</A>. Seen in this photo are (from left to right): Erick Lichte, Jon Iverson, Kalman Rubinson, Larry Greenhill (partially hidden), Blue Smoke's Peter Sills (back to the camera), and someone whose name tag I couldn't see. It gives you an idea of the inquisitorial mode we are in at Shows, desperate for detail but eventually satiated with sound.

Old Times, Good TImes

CES is where you can see the new but it is also where you can catch up with old acquaintances. Caught here in the CES Press Room in Jon Iverson's photo, I'm standing on the left with my partner in Stereophile Inc. for 12 years, Larry Archibald, who is both enjoying his retirement from the high-end audio industry and missing it, and Larry's wife, Laura Chancellor. It was on the 700-mile drive back to Santa Fe, New Mexico, from the CES in January 1986 that Larry, Laura, and I mapped out the future of <I>Stereophile</I>.

dCS Puccini SACD playback system

It's now 10 years since the launch of the two high-resolution audio disc formats, <A HREF="http://www.stereophile.com/asweseeit/164">SACD</A&gt; and <A HREF="http://www.stereophile.com/asweseeit/1099awsi">DVD-Audio</A&gt;. Yet, perhaps partly because both were <A HREF="http://www.stereophile.com/asweseeit/257">hobbled in various ways</A> to please the record industry, perhaps partly because too many supposed hi-rez releases sounded no better than CD, and perhaps partly because record retailers weren't sure how to display the formats to their best advantage, neither took off in any substantive way. DVD-A disappeared, and SACD survived only as a niche format for high-quality classical releases in both two- and multichannel forms. As we got deeper into the same decade, digital technology, despite various sparks and flashes, went into the doldrums. Mainstream digital technology was increasingly concerned with squashing the music into fewer and more portable bits, not with increased sound quality. Even the concept of "CD sound quality" began to seem an unattainable goal, as <A HREF="http://www.stereophile.com/features/308mp3cd">MP3 files</A> became the dominant music carrier.

A Bad Year

Though the January 2010 issue of Stereophile will be hitting newsstands before the holidays, this is nominally the last issue of 2009. But already in October, on my return flight from Denver to New York following this year's Rocky Mountain Audio Fest, it struck me that 2009 had not been a good year for the world of high-end audio. Yes, the worldwide recession has bit deep into the economic health of audio manufacturers and retailers, but in the past 12 months too many of those who have helped make our hobby great, and have helped promote our shared passion for listening to music with as high a quality as possible, have breathed their last.

Aerial Model 5B loudspeaker

In October 2005's "<A HREF="http://www.stereophile.com/thefifthelement/1005fifth">The Fifth Element</A>." I said of the Harbeth HL-3P-ES2, a descendant of the <A HREF="http://www.stereophile.com/standloudspeakers/361">BBC LS3/5A</A>, "Gloriosky, these little speakers are just great to listen to!" Later, in <A HREF="http://www.stereophile.com/standloudspeakers/1293harbeth/index5.html">A… 2007</A>, John Atkinson endorsed that remark.
