As part of this issue's coverage of the recent Consumer Electronics Show (see Sidebar), I report on my dissatisfaction with almost all the surround-sound demonstrations I experienced in Las Vegas. As a music-lover, the last thing I want is to have trumpets and drums attacking me from behind, yet almost without exception, that is what record producers seem to feel is an essential part of the DVD-Audio and SACD experiences.

I have to hand it to Stereophile’s Michael Fremer (right), who also edits AnalogPlanet.com. The man has large attachments! I find cartridge set-up intimidating and I don’t even attempt it until I am in the “zone.” But Mikey does it in public with a video camera amplifying his every motion. At one point in one of his two packed 90-minute seminars at T.H.E. Show, he even picked up the VPI turntable he was working, provided by David Weinhart (left), founder/owner of Ambrosia Audio & Video and owner of Los Angeles retailer Weinhart Design, Inc., to rotate it with the stylus still resting in the groove so the video camera could get a better view! As I said, large attachments.

In common with the mood of our times, there seems to be an increasing amount of bad temper in the High End. There are more people around who, in Jonathan Scull's timeless phrase, have a "level of audiophile rage very close to the surface." Witness, for example, the "cancel my subscription" letter from Professor Daniel H. Wiegand in this issue: he obviously feels a line has been crossed.

As they had done at CES, Andrew Lipinski (right) and Lukas Lipinski set up a full surround system using their L-707 two-way monitors that had so impressed Larry Greenhill when he reviewed them for Stereophile last December.

Loudspeakers from Kentucky-based Tyler Acoustics have created a bit of a buzz on the Internet, but Axpona was my first opportunity take a serious listen to them. The lastest version of the Taylo Reference System shown in the photo ($4800/pair) combines a 6" magnesium-cone midrange unit from SEAS with a 1" soft-dome tweeter from Scanspeak and a 15" woofer from Eminence in a sealed enclosure. Crossover frequencies are 150Hz and 2kHz. The system featured a Basis turntable, Krell CD player, Sutherland phono preamp, and Rogue preamp and monoblocks, wired with DH Labs cables.

Headphone listening is hot these days, due not only to the ubiquity of the iPod as a music source but also because it is possible to get state-of-the-art headphone playback without having to have stupidly bottomless pockets. A plethora of affordable high-quality headphone amplifiers are available, and high-performance 'phones can be had for a few hundred dollars. Used with a computer or iPod to play uncompressed WAV or AIF files or losslessly compressed FLAC or Apple Lossless (ALAC) files, a headphone-based system can offer the audiophile on a budget seriously good sound.

I have been following with interest the goings-on at Nevada-based Wisdom Audio, since the company was revitalized with members of the team that had led Madrigal to success in the 1990s. But their concentration on in-wall speakers, using planar technology developed by David Graebener, means that they fall within the bailiwick of our sister publication Home Theater. Going in their room at CES, however, I was confronted by the LS4 floor-to-ceiling on-wall ($80,000/pair), which sounded magnificent driven by Classé's superb new CT-M600 monoblocks and reinforced below 80Hz by a pair of Wisdom enormous STS 2x15" subwoofers ($10,000 each; STS stands for "Steamer Trunk-sized Subwoofer"). The system controller, which includes an active crossover and room correction, costs $6500.

The LS4 uses four identical push-pull modules, each comprising a central HF section operating above 750Hz flanked by midrange sections covering the 80–Hz range. The backwave is absorbed within the enclosure, but the enormous radiating area still gives a sensitvity of 100dB/2.83V/m. (Impedance is 4 ohms.) Though the LS4 is fastened to the wall behind it, the weight is supported by a single spiked foot.

The LS4 is where architectural audio becomes aspirational audio.

Some products at CES—all-black products, with black highlights, and with the lettering tastefully done in black, in a darkened room—defeat all but the most-determined photographers. So my thanks to Larry Greenhill for managing to photograph the new Classé CTM600 600W monoblock amplifier ($6500 each).

"The large peak at 16kHz reported by Stereophile...was nowhere in evidence...The most probable explanation of this discrepancy is that the [Waveform supertweeter's] very light ribbon depends on the air load for damping, and that load is much smaller in the thin air up there at 7000' in Santa Fe than at altitudes where less lightheaded and scientifically more accountable reviewers dwell." Thus spake Peter Aczel (footnote 1), erstwhile loudspeaker designer and Editor/Publisher of the reincarnated The Audio Critic, a publication that advertises itself as having "unusual credibility among the top professionals in audio."
