As I walked through Stereophile's Taipei High-End Hi-Fi show (see the full report next month), I was startled to see four ladies in their 50s carrying Stereophile bags full of brochures. They'd just left a demonstration of Martin-Logan CLSes driven by Aragon electronics and were talking animatedly among themselves as they busily made their way to the next exhibit room. My surprise was repeated throughout the show as I saw an amazingly diverse group of people who had enough interest in high-end audio to get themselves to the Taipei Hilton and pay the show's admission price. Young couples, old couples, entire families, and women were all there to see and hear high-end audio. This was in sharp contrast to the narrow demographic group seen at US and European hi-fi shows: predominantly young to middle-aged males to whom audio is a hobby.
A man who had just looked through his very first Stereophile---April's "Recommended Components" issue picked up at a newsstand---recently called to ask my advice on a certain inexpensive CD player made by a large mid-fi company. I told him I hadn't auditioned the player and thus couldn't comment on its worth. The man then proceeded to read me the player's specifications, finally informing me that the player "had the new 1-bit thing"---all in the belief that I could make a recommendation based on what he'd just told me. He apparently had been conditioned to believe that not only was "the 1-bit thing" superior, but that choosing a CD player was merely a matter of evaluating technical specs.
I should begin this review by confessing that I've never been a fan of subwoofers. Most subwoofer systems I've heard have been plagued by a familiar litany of sonic horrors: poor integration between subwoofer and main speakers, boom, bloat, tubbiness, slowness, excessive LF output, and an overall presentation that constantly reminds the listener he is hearing a big cone moving. To me, subwoofers often sound detached from the music, providing an accompanying thump that bears little relationship to the sound from the main speakers. Rather than revealing the music's harmonic underpinnings, subwoofers often obscure them in a thick morass of featureless boom. In addition, adding a subwoofer often destroys the qualities of the main speakers that made you buy them in the first placejust to name a few of my observations (footnote 1).
As founder of California-based Vacuum Tube Logic of America, David Manley is at the forefront of the current renaissance in vacuum-tube audio equipment. In addition to manufacturing some highly regarded audiophile components, VTL has introduced a line of tubed professional equipment that is finding its way into recording studios. David has a lifetime of experience in tube electronics, recording studio design, disc cutting, music recording, and most recently, analog/digital and digital/analog converter design.
The past 12 months have seen some remarkable developments in digital playback. Standards of digital musicality are far higher than they were a year ago, both on an absolute performance basis and in terms of what you get at various price levels. No other component category has seen such tremendous gains in value for money or number of new products introduced. It seems hard to believe that since Vol.13 No.6 (12 issues ago), we've reviewed such noteworthy digital processors as the Meridian 203, Proceed PDP 2, Stax DAC-X1t, Theta DSPro Basic, Wadia X-32, Esoteric D-2, PS Audio SuperLink, and VTL D/A. Each of these converters brought a new level of performance to its price pointor, in the case of the Stax and VTL, established a new benchmark of ultimate digital performance.
Just as these units provided stiff competition for previous products, so too will they come under the assault of improving technology. The art of digital processor design is so young that we can continue to expect further improvements coupled with lower prices as designers move up the learning curve.

The whole field of subjective audio reviewinglistening to a piece of equipment to determine its characteristics and worthis predicated on the idea that human perception is not only far more sensitive than measurement devices, but far more important than the numbers generated by "objective" testing. Subjective evaluation of audio equipment, however, is often dismissed as meaningless by the scientific audio community. A frequent objection is the lack of thousands upon thousands of rigidly controlled clinical trials. Consequently, conclusions reached by subjective means are considered unreliable because of the anecdotal nature of listening impressions. The scientific audio community demands rigorous, controlled, blind testing with many trials before any conclusions can be drawn. Furthermore, any claimed abilities to discriminate sonically that are not provable under blind testing conditions are considered products of the listeners' imaginations. Audible differences are said to be real only if their existence can be proved by such "scientific" procedures (footnote 1).
Last July I reviewed the $4850/pair Hales System Two Signature loudspeakers and enthusiastically recommended them. In fact, they displaced the B&W 801 Matrix 2 as my reference loudspeaker, and have become a fixture in my listening room. Over the past seven months, my impressions of the Signatures have been largely confirmed: transparent and uncolored midrange, resolution of fine detail, precise imaging, superb transient abilities, and, most importantly, an ability to thoroughly involve the listener in the music. These qualities earned the Signature a Class A recommendation in Stereophile's "Recommended Components." I've greatly enjoyed the many hours spent with the Signatures.
Hales Audio makes another loudspeakerthe System Two reviewed herethat is very similar to the Signature, but much less expensive (footnote 1). Because the System Two is such a close relation to the Signatureit uses identical drivers, a nearly identical crossover, and similar cabinet constructionand costs nearly 2 kilobucks less, I was eager to hear what the smaller system had to offer. Because the Signature was recommendable at $4850, the System Two just might be a bargain at $3000 if it even came close to the Signature's musicality.
The Snell Type C/IV's design has been highly influenced by both the testing methods and philosophy of Canada's National Research Council in Ottawa. Other well-known loudspeakers to have benefited from the NRC's testing facilities include the Mirage M-1 and M-3, PSB Stratus Gold, the Waveform, and Camber 3.5. The NRC provides a variety of services to loudspeaker designers, notably use of their testing facilities which include a full-sized anechoic chamber. In addition, the NRC is heavily involved in carefully controlled blind listening comparisons between loudspeakers, used to aid the loudspeaker designer while the product is under development. The NRC doesn't provide design services, but rather the means of testing and evaluating work in progress and finished products.
Despite not offering design aid, many loudspeakers created with the NRC's testing and listening laboratories share some common philosophies. Chief among these is the belief that flat amplitude response is far and away the most significant factor in listener preferences and thus should be the paramount design goal. Many NRC-influenced loudspeakers share steep crossover slopes, wide dispersion, smooth off-axis response, and pay considerable attention to the way the loudspeaker interacts with the listening room.
