LATEST ADDITIONS

Sharing a Hilton ballroom with Legacy and AVM, the Austrian Ayon tube amplification was being demmed with Lumenwhite Artisan speakers ($40k/pair). Source was the new Ayon Music Server and two-box preamp. Listening to Pink Floyd's "Another Brick in the Wall," I thought the sound was better than it had any right to be given the suboptimal acoustics. Then I spotted some of the Synergistic ART Acoustic bowls on the walls—my left brain knows these silly little bowls can have no audible effect on room acoustics in the audio range; my right brain was busy telling my feet to tap!

Like the MartinLogan speakers in the next story, the Belgian Venture Ultimate speakers ($59,500/pair), distributed in the US by Precision Audio & Video, were set-up in a room that was really too big for them. Even at a fairly close listening distance, the room's reverberant field was dominating what I was hearing. Even so, on "Good Morning Little Schoolgirl" from Muddy Waters' Folksinger, this three-way, five-driver tower had a natural tonality, precise stereo imaging, and a full-range sound. The 48.5"-tall, 152lb Ultimate has a specified frequency range of 26Hz–40kHz, a nominal impedance of 6 ohms, and a sensitivity of 90dB/W/m.

Whether they be Quads or Staxes, Roger Sanders' designs, or MartinLogans, electrostatic speakers generate passionate advocates. Retailer Digital Ear was demming the enormous Martin-Logan CLX speakers ($25,500/pair) in a huge ballroom in the Atrium hotel, along with two MartinLogan Depthi subwoofers, driving them with McIntosh MC601 monoblocks, a McIntosh C50 D/A preamp and a Meridian-Sooloos server, all hooked up with Transparent cable. The CLX's curvilinear section operates above 360Hz, meaning that all the harmonics of the music and the upper fundamentals are not interrupted by a crossover. Unlike Jason Serinus, I love Diana Krall's music making, so I requested a track from her Live in Paris album. Despite the size of the room, her version of Billy Joel's "Just the Way You Are" was reproduced with Ms. Krall's voice palpably hanging in the center of the stage.

Zu Audio's room was like no other. While the "normal" set-up has components facing attendees and carefully stacked on equipment racks, Zu more or less duplicated the DJ experience. Spinning vinyl as if in a cage, and very happy to be there, I might add, sat Zu owner Sean Casey's delightfully high-spirited son, Ian.

One of my fondest memories of a past CES was sitting with John Atkinson at T.H.E. Show, playing a track from one of his superb recordings of Cantus on an all-out darTZeel /Evolution Acoustics system from Jonathan Tinn's Blue Light Audio. Here, on more modest speakers and electronics, I was again blown away, this time by the fabulous soundstage height, three-dimensionality, and realistic depiction of horns and cymbals on Michael Tilson Thomas' recording of Mahler's Symphony 3.

You couldn't miss the signage for PrimaLuna and Nola; it was as big as the excellent signage for T.H.E. Show itself. You also couldn't miss the sound: lovely, warm, and extremely inviting. Although the system was playing a bit too loud for the room, the system handled bass extremely well, and made timbres on a (yes) Diana Krall recording pretty natural. Doing the honors were the Nola Ko loudspeaker ($9800/pair) and three components from PrimaLuna: Premium CD player ($3995), DiaLogue 3 linestage preamplifier ($2695), and DiaLogue 7 monoblock amplifiers ($5495/pair).

Late on Saturday afternoon, Emotiva's hall-end room at the Hilton shifted into college fraternity mode. The Emotiva Stealth 8s ($1499/pair) and ProDAC ($699), connected with Emotiva cables, were blasting mono-tonality assaultive rock that, for all I could tell, was sourced from MP3. The bass was huge, the highs searing, the outcome lamentable. I'll bet, if John Atkinson had analyzed what was playing for one of his seminars on how compression is ruining the pop music industry, his meters would have read red, red, red.

As you will read in the next story, it was a very different story in Emotiva's second room. Thank God.
