Consider this: While Ayre calls its new DX-5 ($10,000) a "universal A/V engine," the disc player doesn't have a coaxial or a TosLink S/PDIF input. That appears crazy to me, but to Ayre, no. They've found their own road.
There is something about the performance of music that is in the nature of a spectator sport. By this I do not mean big-arena stagecraft and lights and fireworks and dance routines. I mean the actual making of the music.
To see Eric Johnson's fingers flying over his Fender Stratocaster as he hits "Cliffs of Dover" out of the park one more time is to enjoy something that is every bit as much an athletic performance and a spectator sport as baseball is. There is a thrill to watching people do difficult things exceptionally well, things that most of us can only take random sidelong swipes at.
Although, historically, Asian high-performance loudspeakers have not had much impact in the US (with the possible exception of the Yamaha NS1000), it is obvious from recent events that that situation might change. Some Japanese manufacturers are determinedly attempting in 1989 to scale the high-end heights. Onkyo, for example, launched an entire range under the Precise brandname, designed by that most idiosyncratic of talented Californian engineers, Keith Johnson, while Yamaha has licensed the Swedish ACE-Bass technology to produce loudspeakers that extend amazingly low in the bass for their size. But it is Pioneer, already well-ensconced in the US pro market with their TAD (Technical Audio Devices) drive-units and monitors, who have made perhaps the biggest techno-splash with their "Elite-TZ" speakers. These feature both high-tech drive-units and a novel (if not entirely new) method of minimizing enclosure vibrations.
The TZ-9 is the top of Pioneer's new line, and costs a cool $4000/pair, placing it firmly in the high-end category. But for that outlay, the TZ-9 owner acquires a largish and quite handsome speaker, finished in a rather orange-colored oak veneer and standing some 4' high. Both tweeter and midrange units feature domes fabricated from an amorphous form of carbon termed by Pioneer "Ceramic Graphite," which is said to have 10 times the bending stiffness and two times the internal loss or self-damping of an equivalent titanium dome. The practical result should be accurate pistonic motion in each unit's passband, with a better-damped HF resonance than a metal dome. In practice, these Ceramic Graphite diaphragms can be quite brittle. Despite the presence of protective wire grilles over the mid- and high-frequency units, the first pair of TZ-9s we received had had the midrange domes shattered, due to inadequate early packaging.
It seems to me that it should be possible to make a perfectly jitter-free CD transport without resorting to elaborate, expensive mechanical structures. This idealized transport would ignore all mechanical considerations of disc playbackvibration damping and isolation, for exampleand simply put a jitter-free electrical driver at the transport output. If such a circuit could be made, it wouldn't care about how bad the signal recovered from the disc was (provided the recovered data were error-free). The circuit would just output a perfect, jitter-free S/PDIF signal. The result would be the sound quality of the $8500 Mark Levinson No.31 Reference CD transport in $200 machines. Such a scheme would provide an electrical solution to what has been considered largely a mechanical problem.
But back in the real world there's no doubt that attention to mechanical aspects of transport design affects sound quality. Examples abound: listening to Nakamichi's 1000 CD transport with its Acoustic Isolation door open and closed; playing the Mark Levinson No.31 with the top open; and putting any transport on isolation platforms or feet are only a few of the dozens of experiences I have had that suggest that mechanical design is of utmost importance.
