Thiel's press conference at the Sands Convention Center on Day One of the 2008 CES opened with a detailed critique of the complexities and challenge of installing a home theater system. Ekin Binal, Vice President, Product Development, of BICOM, an IT company partnering with THIEL to address these issues, spoke in detail about the complex, labor intensive, time-intensive, cost-intensive installation of multiple speakers and channels. Furthermore, updating such a home theater system is never simple nor convenient, nor is moving a system from an old house to a new house either simple or inexpensive. Because installation is custom work, there is no universal package a single manufacturer can create that can fit most domestic locations.

"Wow, that's great," I said, looking down at B&W's new $599 Zeppelin iPod player, the football-shaped Zeppelin, as it played a track from Tal Wilkenfeld's new Transformation album off of my Apple iPhone. Tal Wilkenfeld, a 21 year-old, very pretty, Australian girl, was all the buzz after she played bass with Jeff Beck at Eric Clapton's Crossroads Festival Concert in Chicago last summer.

"The best loudspeaker on earth!" proclaimed the sign for the YG Acoustics Limited Exhibit. The company's founder, designer, and CEO, the ever-upbeat Yoav Geva, was just as proud as the papa of his new $33,000/pair "Kipod" floorstanding speaker. And proud he should be. "Kipod means hedgehog," he told me, "which is my daughter's nickname because of her hairstyle."

When I arranged to review the Bryston 28B-SST monoblock power amplifier, I wanted to be certain that the 1kW amplifier wouldn't be starved for current. Bryston advised me that Plitron, who manufacture the 28B-SST's toroidal transformer, also make Power Isolation Units (PIUs), under the brand name Torus Power. Torus explained that its PIUs combine surge suppression with massive toroidal transformers to provide AC power conditioning and protection from voltage surges.

Carl Kennedy, director of JL Audio's Home and Professional Sales division, leaned forward and quietly asked, "Would you like to review our Fathom f113 subwoofer?"

I've long admired Vacuum Tube Logic's line of amplifiers and preamplifiers. Owners Luke Manley and his wife Bea Lam routinely appear at the Consumer Electronics and Home Entertainment shows with luxurious, microprocessor-controlled tube gear, soothing new music, good-sounding rooms, and a friendly, unhurried manner. Their show setups are dialed in so well that I often find myself taking refuge there, sitting and listening for hours with other Stereophile writers.

Patrick Chu, creator and designer of the $80,000/pair, two-way, Mandarin Supreme loudspeaker, explained that the products’ name is a synthesis of two words: Loimin means "delightful understanding" and Chay means "ateliar or studio." The frequencies from 750Hz upwards are handled by a 1" tweeter loaded with a 19" horn comprised of alternating layers of cherry and oak wood. The bass, which is rated down to 22Hz, is handled by 10" and 12" woofers. This composite was by far the least active speaker material I've come across. Rapping it with my knuckles was like tapping on granite. The woofer enclosure was made of concrete with a cloth covering. I didn't ask about the loudspeaker's weight because I didn't want to know. The nominal impedance is 8 ohms, and the voltage sensitive a very high 92dB. Although I didn't audition any familiar reference recordings, the speaker had a dynamic sonic texture with a midrange emphasis.

...and 3.6kW into 2 ohms! All in a day's work for Krell's $40,000/pair, Krell Evolution 900 monoblock amplifier. On passive display with its top off, you can see that the amplifier has three output modules, each containing a pair of driver stages, 28 bipolar output devices, and a massive heatsink that vents heat in chimney fashion through vents in the top and bottom of the chassis. The power supply features two 3kVA toroidal transformers, 52 electrolytic capacitors, each rated at 1800µF, 900watt, and 105°F. Weight? Again I didn't want to know, but was told it was a mere 175 lbs!

"That's an impressive soundstage for a two-way monitor," I thought looking at the diminutive Confidence C1 loudspeaker, but hearing a wide, deep soundstage. Dynaudio's 25 lb pound, two-way ($7000/pair plus $450/pair for two) features a 7" woofer and the Danish company's acclaimed Esotar2, 28mm, soft-dome tweeter. The drivers are mounted on a baffle that is said to be decoupled from the cabinet. Dynamic range was superb driven by Simaudio Moon W-7M monoblocks, thought JA, who thought that this system's reproduction of Stereophile's new Attention Screen CD was one of the best he heard at the Show.

Todd Eichenbaum, design engineer at Krell, walked me through the design of their new amplifier, the $10,500, 300Wpc 302. The power supply employs a 3kVA toroidal transformer, built-in power conditioning, a current-mirror input stage, a push-pull driver stage, and low negative feedback (8dB) around the output stage. It was paired with the $10,000 Evolution 222 stereo preamplifier.
