LATEST ADDITIONS

It's been a long time coming, but it is finally happening. As I write these words, T.H.E. Show (aka The Home Entertainment Show), the successor to the late Richard Beers' original T.H.E. Show that began as an alternative high-end showplace to CES, is about to begin in the Long Beach Hilton. (That's Long Beach, California, for the uninitiated.) Dealers and exhibitors have set up in 20 or so rooms and numerous marketplace booths, said their prayers, enjoyed dinner in the hotel or in downtown Long Beach, and begun to burrow in for the night. As they do, components cook, cables settle, and the acoustic gods and karmic gatekeepers prepare to hold their traditional midnight meeting of the minds to decide each exhibitor's fate.

This is a speaker we've been fairly intimate with over quite a period of time. Designed by John Bau, the SC-50i started out three years ago as an inexpensive speaker system ($330/pair) not sold through dealers.

One of the factors allowing it to cost so little was the clever adaptation of cardboard tubes, normally used as forms for pouring concrete pillars, for use as speaker enclosures. They have a number of advantages, other than low cost: their circular form helps eliminate resonance of the back wave within the enclosure; the material is rigid because of its shape, and is non-resonant due to its construction.

As ALF would say, "There's more than one way to cook a cat." We've been so overwhelmed with linear pulse-code modulation (PCM) recording, we forget there are other ways to pass from the analog domain to the digital.

One of these is delta modulation. The Greek delta (which in its upper-case, block-letter form, looks like an equilateral triangle) is the mathematical symbol for the difference between two quantities; accordingly, in delta modulation, we record not the absolute value of a signal sample, but the difference between successive samples.

How do you like your tangential-tracking tonearm: with a captured air bearing? If so, a stationary bearing and moving rail—or a moving bearing and stationary rail? A hovercraft-style air bearing? Trolley-wheel or servo-mechanical bearing? Or pivoted, with some kind of offset at the pivot or the headshell—or both? In today's crowded market of analog playback, you can buy whatever type of tangential tracker you prefer, from Bergmann, Clearaudio, Kuzma, Reed, Schröder, Thales, and others.

MQA has once again floated to the surface of the perfectionist-audio pond—not belly-up as some have hoped but forced there by relentless pursuit by anti-MQA predators posing as impartial jellyfish.
