The Jeff Rowland Design Group has long been renowned for the exquisite quality of its chassis. The company was one of the first to promote fully balanced topologies in preamplifiers and amplifiers in the high-end market, one of the first to offer a sonically acceptable remote control, and one of the few to offer a battery power option for their amplifier line.

Audio Artistry's Beethoven is the banner model of the company's Composer series (footnote 1), which includes the entry-level Vivaldi as well as the Dvorak I reviewed in the April 1996 Stereophile (Vol.19 No.4, p.204). Like the Dvorak, the Beethoven is a four-piece, bi-amplified, dynamic dipole design; unlike the Dvorak, the Beethoven has been taken to the nth degree of refinement.

A thorough exploration in a magazine article of such a pervasive and complex topic as vibration control in audio systems is next to impossible; vibration and sound are so intimately bonded that it would be very easy to extend this discussion to just about any area of interest in audio. My intention here is simply to lay a foundation for understanding the basic mechanical forces affecting our quest for improved sonic fidelity, and in the process provide the tools for anyone to achieve good, practical vibration control in his or her system.
