LATEST ADDITIONS

It was released in 2009, but Krell's Modulari Duo Reference loudspeaker ($65,100/pair) was new to me when I visited THE Show and ventured up to the 28th floor of the Flamingo. The two-box speaker features all-aluminum enclosures, and features twin port-loaded woofers and a ring-radiator tweeter. The Modularis were hooked up with Zen Satori cable to Krell's new Evolution 2250e amplifiers, which offer 250Wpc into 8 ohms and 500Wpc into 4 ohms ($20,000/pair). Also new to the Connecticut company's line at CES was the Phantom preamplifier ($17,500, or $20,000 with optional crossover module, completely adjustable for high-pass and low-pass slopes and frequencies) and the 525 CD player ($12,000 in basic form).

I was initially confused when I walked into this room, as there appeared to be two different systems set-up, with loudspeakers from two different manufacturers. However, playing while I was there were the new Legacy Audio Focus SE speakers in Black Pearl finish (left, $8995/pair), with the Lumenwhite Artisan speakers (not quite so left) silent. Common to both system was an Ayon Audio CD55 CD player and Synergistic Research cables, and Ayon Triton tubed monoblocks drove the Legacies.

Broadly similar in concept to the Focus 20/20 speaker that Paul Bolin favorably reviewed in January 2004, the 25th Anniversary Focus SE is considerably more refined. It uses an AMT supertweeter and a leaf tweeter, between two unique 7" midrange units that use a cone comprising a sandwich of Rohacell and a weave of silver wire and graphite. The two 12" woofers take over below 200Hz and have a low-Q ported alignment to take advantage of the usual room gain without booming. Frequency range is specified as 16Hz–30kHz and sensitivity a very high 95.4dB (4 ohm impedance).

The cabinet is narrower and deeper than the older speaker's, with sculpted edges that progressively reduce the baffle width for the HF drivers to optimize diffraction. The crossover uses Solen metalized polypropylene capacitors and braided silver Kimber Kable is used to connect the supertweeter. The drive-units are matched to within ±0.25dB and designer Bill Dudleston hand-tunes the crossover network of each SE speaker.

Hansen's cost-no-object speakers have always sounded excellent at CESes, so one of the first rooms I visited at the Venetian was Hansen's, to hear the new The King E (for Enlightened) loudspeaker ($98,000/pair). A 63"-tall, 6-driver, 3-way design weighing 420lbs, The King E was being driven by Tenor mooblocks and preamp, with the front-end a Clearaudio turntable fitted with a Graham Phantom II tonearm. (My apologies for not noting the phono cartridge being used.)

Listening to a 45rpm remastering of Manuel de Falla's The Three-Cornered Hat, I was struck by the effortless sweep of sound and low-frequency performance that suggested that The King's specified frequency response of 18Hz–23kHz was not hyperbole. Percussion and pizzicato strings had a start-stop character that was very lifelike, with not a hint of overhang or boom.

The Stein Music Harmonizers (approx. $1100 each; distributor Walter Swanborn of Fidelis AV is putting together package deals that include Stein’s Harmonizer accessories) are one of those mysterious sound-improving devices that are hard to explain to those who have not heard them. They certainly impressed Sam Tellig, who recently discussed them in his monthly Stereophile column.

They’ve also impressed me greatly. A set of four Stein Harmonizers has been residing in my reference system in Oakland for several months, bringing me much pleasure. To these ears, when set up correctly, they have a far from subtle effect on three-dimensionality, transparency, and realism. They take me one step closer to the real thing, making what comes out of my speakers sound less like hi-fi and more like music.

I was delighted to spend some time at T.H.E. Show with the Harmonizers’ designer, Holger Stein of Germany. Stein was showing the newest version of the Harmonizers, which were five years in the making.

The latest Harmonizers have a three-position switch on the rear. Those positions are (1) on with light, (2) on without light to preserve battery life for up to two years, and (3) off, to save energy when the system is not playing. Besides that, they function identically to their predecessor (which I have).

So how does the Stein Harmonizer work? Best to quote directly from Stein. Since, for him, English is a second language, I’ve given him an assist in the editing department:

AAudio Imports' Brian Ackerman holds what must the world's most expensive AC strip, the Weizhi PRS6. Priced at $3200, the PRS6 is machined from a block of Super Duralumin alloy and features a graphite grounding module. There are no isolating transformers or conditioning circuits, the PRS6 is purely passive. The thinking behind the product, said Brian, is "to get the noise out of the line without changing the sound."

Yes, the Weizhi is a gorgeous piece of audio jewelry but do people really pay $3200 for peace of mind? Brian told me that he is currently shipping 10 units a week, so I guess they do.

Audioquest formally released their current top-of-the-line reference USB cable at CES, the Diamond USB ($650/1.5m). The cable’s conductor is solid-core, perfect-surface silver (100% silver).

A key feature of the Diamond USB, which is held in the photo by Audioquest’s Andrew Kissinger, is the Audioquest DBS (dielectric bias system). Invented and patented by Richard Vandersteen, with the cable version co-patented by Vandersteen and Audioquest’s Bill Low, the DBS creates an electrostatic field that saturates and polarizes the molecules of the insulation to minimize energy storage in the dielectric. The result is claimed to be much greater dynamic range, lower background noise, and reduced phase distortion.

Steve Silberman, VP of Marketing, explained that all insulators have capacitance. Energy from the conductor enters the insulation and needs to discharge. The DBS’ electrostatic field lowers the discharge, which in turn lowers the amount of phase distortion and makes for a cleaner signal.

In a very short demo, Silberman compared music through a stock USB cable that came with his printer to music through the Diamond. Using the new Arcam R asynchronous USB DAC, Arcam AVR 600 receiver, AQ Niagra interconnects ($1600/1m pair), AQ Redwood speaker cables ($2300/3ft pair), and Vandersteen 2Ce 30th anniversary edition speakers, the difference in transparency and color was striking.

Joe Lavrencik, owner of Critical Mass Systems, designs all Critical Mass Systems Precision Component Support Systems. All of the company’s products are built in the Chicago area.

The newest Critical Mass product is Maxxum ($5650 per shelf), a precision component-support system. The shelf and rack architecture operate together to mitigate vibration in the floor, the rack, the shelf, and the component at the same time.

“We do more than isolate,” the sleep-deprived designer offered by way of explanation. “We give energy in the air a pathway out of the component so that components are not saturated with vibration from the loudspeakers.”

Lest you think Critical Mass Systems only manufactures high-priced products, prices start at $195 for a set of four MXK spikes, and $195 for a basic shelf. “Even though we’re very expensive, we start very low,” says Lavrencik.

At CES 2011, Critical Mass Systems products were used in the Lamm, Hansen/Tenor, and BAT rooms. In the photo, Lavrencik kneels near his Maxxum amplifier/component stands ($5650/each) and the Lamm ML3 Signature monoblocks ($139,290/pair) being used to drive Wilson Alexandria II speakers.
