Art Dudley mentioned earlier in this show report the Audio Power Laboratories tube monoblocks driving Wharfedale's new Neo Airedale flagship loudspeakers ($25,000/pair). Source was a Musical Fidelity CD player, preamp an Audio Research, and the sound in this room was indeed one of the best at Axpona: extended lows, clean highs, and impressive dynamic range.
Zesto Audio was a name new to me, but their versatile Andros PS1 tubed MM/MC phono stage ($3900) was getting great sound from Billie Holiday's "Day In, Day Out," played on a Thorens TD309 player ($1900) fitted with a Dynavector DV-20X2L cartridge ($850). The rest of the system comprised a ModWright LS 100 tube preamp ($3495) and ModWright KWA 150 solid-state amplifier driving Fritz Carbon 7, Rev.5 speakers ($1795$1950/pair), wired with WyWires.

One of the enduring myths of audiophilia is that of the recording as a true and honest picture of a musical event—a sonic "snapshot" that captures a unique moment of time the way a photograph captures the light of a day long since past.
Neil Sinclair gave me a tour of Theta’s new multi-channel amp, which keeps the signal exclusively in the digital domain from the S/PDIF inputs to the PWM output stage, the latter said to operate at the super-high frequency of 1MHz. Designed by veteran amp engineer Dave Reich, what is in effect a powerDAC—that’s what it says on the output-stage printed circuit boards—will find its way, I hope, into some two-channel products in due course.

We received the following press release last night. No more information was available and there was no word when this story was first posted on whether or not Thiel cofounder Kathy Gornik will remain with the company. Since then, however, CEPro.com has reported that Kathy and her daughter Dawn Cloyd, who was director of international sales, will both leave Thiel. Why the sale? Our suspicion is that while Thiel remains a great brand, it is too small a company, with no access to a significant source of capital, to be able to compete effectively in today's market.
Kentucky manufacturer Thiel has acquired a reputation for the coherence of sound presented by its range of distinctive, sloping-baffle, floor-standing loudspeakers. Designer Jim Thiel gives a high priority to linearity of phase response; as a result, he chooses to use phase-linear, first-order crossovers in his designs, the target response being the combination of electrical and mechanical filtering. As the out-of-band rejection is then only 6dB/octave, it places demands on his chosen drive-units to be well-behaved, not only in their passbands, but also outside of them. In effect, the loudspeaker has to be designed as a whole system, the interaction between the drive-units and crossover being considerable.
In the past year, Stereophile has reviewed a number of cost-no-object flagship loudspeakers. B&W's Signature 800, MartinLogan's Prodigy, Burmester's B-99, Snell's XA Reference Tower, Krell's LAT-1, Linn's Komri, Dynaudio's Evidence Temptation, Sony's ES SS-M9ED, and Rockport's Antares have all passed through the review mill. Manufacturers like to submit their flagships for review for a number of reasons, not the least of which is the pride they take in showing what their engineers can do when given a blank check. However, while all these models do indeed provide great (if different) sound for the tens of thousands of dollars they demand from their owners, they are out of reach of the majority of audiophiles. It is important, therefore, for reviewers to spend time with real-world designs; when I heard the $1990/pair CS1.6 from Kentucky's Thiel at the 2002 CES last January, I requested a pair for review.
As a reader pointed out, missing from Wes Phillips' coverage of Wednesday's Thiel CS3.7 press conference was a picture of the new speaker. Here it is, pictured with Jim Thiel waxing lyrical about his new midrange diaphragm.

I've said it before and I'll say it again: a would-be loudspeaker designer shouldn't even start to think about the possibility of maybe designing a full-range, multi-way loudspeaker until he (and they do all appear to be men) has cut his teeth on a small two-way design. There is still as much art as science in designing a successful loudspeaker, even with all the computer-aided this and Thiele-and-Small that, that even a two-way design requires a designer either to be possessed of a monster talent or of the willingness to undergo months, even years, of tedious and repetitive work—or of both. For a would-be speaker engineer to start his career with a wide dynamic-range, multi-way design, intended to cover the entire musical spectrum from infra-bass to ultra-treble, seems to me to be a perfect case of an admittedly well-intentioned fool rushing in where any sufficiently self-critical angel would fear to tread.
A reviewer's life is not all fame and fortune. There are downsides, too, one of which is that, while many great-sounding components pass through your listening room, only a few get to stay there on anything like a permanent basis. (And that involves money changing hands, as in [gasp!] "purchase.") Before I bought my long-term reference loudspeakers—a pair of B&W John Bowers Silver Signatures—back in 1994, the speakers that had spent the most time in my 2900-cubic foot listening room were a pair of Thiel CS2 2s. I reviewed the '2 2 in the January 1993 issue of Stereophile (Vol.16 No.1), and although it was relatively affordable ($2250/pair at the time of the review), it did most of what I wanted a speaker to do. Other than a limited dynamic range in the bottom audio octave and a slightly exaggerated top octave, the CS2 2 sounded effortlessly smooth and free from coloration throughout the midrange and treble. It was also a real imaging champ.
