LATEST ADDITIONS

Suweet! Beyerdynamic head headphone designer Gunter Weidemann is responsible for the T1 headphone (open back; $1295) and its extraordinary driver that exceeds 1 Tesla of magnetic field strength. Previous high-end Beyerdynamic designs delivered 0.6 Tesla; the new driver delivers 1.2 Tesla in the gap. Field strength is nothing without low moving mass, so significant effort has been exerted to design a novel and performance-based diaphragm and voice-coil to provide speed and absence of diaphragm break-up. My significant experience with these cans puts them in the world-class category in my mind; especially remarkable for their natural and powerful vocal range reproduction.

Also, I think anything named after Nicola Tesla (and not a rapper, dammit) is really cool.

When I walk into the room, Amphion’s Anssi Hyvönen is demonstrating a small, attractive system made of Audio Analogue electronics and Amphion loudspeakers. He talks about the calming nature of music, and then he does something unexpected: He turns the volume down...

Avantgarde's Armin Kraus stands next to the new version of the three-way Duo speaker, the Grosso ($36,000/pair). Finished in "Lamborghini Orange," the Grosso substitutes two 12" woofers for the Duo's 10-inchers, and drives them with twice the amplifier power. The midrange and treble horn units are the same, but the speaker is now supported by a sturdier space-frame with spikes that are adjustable from above. And again, this is a horn speaker that offers the advantages of horns—high dynamic range, sensitivity, and "jump factor"—without the disadvantages, such as midrange coloration.

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.

Bluebird Music's Jay Rein wanted to hear the Bluetooth-driven Chordette Gem-based system at the front of the room, with Spendor A6 speakers, but my attention was drawn to the familiar-looking speakers at the other end of the room, Peak Consult El Diablo Vs ($89,000/pair), which Michael Fremer reviewed in May 2007. Jay explained that he is ow the North American distributor for these Danish speakers.

The speakers were being driven by Chord SPM1400 monoblocks ($$32,900/pair) and a Chord CPS5000 preamp, with van den Hul's new Mountain interconnects and Nova speaker cables. Jay put the Reference Recordings CD of Scheherazade (RR-89CD) with Jose Serebrier conducting the London Philharmonic Orchestra into the Chord Red Reference Mk,II CD player ($25,900) and for an all-too-brief interlude, I was transported from the fake glitz of Las Vegas into the more real sonic world of the Arabian Nights.

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:
