The lacquers from which LPs are pressed are cut in a straight line, and that's how the LP groove should be traced. Even when set up perfectly, a pivoted arm describes an arc across the disc surface, maintaining tangency to the groove at only two points on that arc. Yet despite numerous attempts at building and selling linear-tracking tonearms, few remain on the market, and most are fraught with technical problems. Linear-tracking arms can be anything but linear, committing more sins of geometry as they meander across the record surface than do their pivoted brethren.

Thirty-one flavors may work for an ice-cream chain, but a speaker manufacturer who sets out to please every sonic palate ends up with a serious identity crisis, pleasing no-one. From its inception in 1985, Audio Physic, based in Brilon, Germany, has been an event-oriented speaker company. Founder and original chief designer Joachim Gerhard focused much of his attention on providing listeners with the sensation of "live" by emphasizing coherent three-dimensional imaging and soundstaging—though not to the exclusion of timbral accuracy. Except for the Medea, based on a Manger driver (a fascinating design nonetheless), every Audio Physic speaker I've heard has fulfilled the company's mission statement.

"It costs as much as a car—and not a used jalopy, either." That's what goes through your head as you contemplate this magnificent $20,190 piece of audio jewelry. I don't mean "jewelry" pejoratively; the tubed Jadis RC JP80 MC Mk.II is a gorgeous, gleaming hunk of retro-looking machinery. Two hunks, actually: an equally large remote power supply is connected via an umbilical cord terminated with an elbow connector the size of house plumbing.

Loudspeaker design is an art and a science. Anyone who tells you it's only one or the other is probably building or listening to some awful-sounding speakers. Design a speaker in an anechoic chamber for the "theoretical" world, and there's no guarantee it will sound good in the real one. Even building a speaker that excels at "real-room" measurements doesn't guarantee that it will sound all that convincing when reproducing music. We can't measure everything, and what we can measure can't be reliably ranked in terms of what's important to most listeners.
