Stand and Rack Reviews

Of late, Stereophile has written a lot about vibration-isolating footers under loudspeakers. The idea of isolating loudspeaker vibrations from floors is controversial. Many (perhaps most) designers believe that dynamic loudspeakers in particular—those with significant moving mass in their cones—should be rigidly connected to the floor as is typically done with spikes. A rigid connection of the speaker to the floor reduces the Newton-1 reactive motion of the cabinet in response to the motion of the cones, heavy woofers in particular. Cabinet motion could be expected to smear the loudspeaker's sound.

In the early 1960s, young people who were anxious see the Beatles on The Ed Sullivan Show had to first sit through a seeming eternity of bad comedians, bad puppet shows, and acrobats spinning dinner plates to the tune of Khachaturian's Sabre Dance. So it is here: Before I can get to the Miyajima Saboten L phono cartridge, I have to report on something I left out of my April 2018 column, which was devoted to Zu Audio's modification of the classic Denon DL-103 cartridge. And since this is information I've been holding on to for almost a year, I suppose I also left it out of my August 2017 column, which was devoted to the MusiKraft Audio's own modification of the Denon DL-103.

One more word for unhappy consumers, in any marketplace, who confuse praise for the new with rebuke for the old: 20 years on, I continue to admire the best qualities of my Linn Sondek LP12 turntable (itself not the first LP12 I've owned). I smile to think of all the records I enjoyed during those two decades.

About once a week, I hear about some new audio accessory heralded by breathless claims of stunning performance gains that "you've got to hear for yourself." Most of these I ignore, and of those I do consider, nearly all wither when subjected to logical engineering analysis. Every so often, however, one of these wonder widgets finds its way into my system.

When American architect Louis Henri Sullivan said "form ever follows function" (footnote 1), he was referring to the transition from the 19th-century view of architecture, driven by aesthetic concerns, to the bold new 20th-century approach of beginning with a building's functions, and letting the design flow from there.

It's no longer news that uncontrolled spurious vibration is one of the greatest threats to high-quality sound and video reproduction. Source components are, by themselves, a nightmare to isolate from the omnipresent vibrations in the environment. The intrusion of uncontrolled spuriae into the playback of LPs, CDs, SACDs, and DVDs has a deleterious and occasionally disastrous effect on the ability of the stylus or laser to precisely do its almost-molecular-scale job. Electronics are nearly as susceptible to such vibration-induced headaches as microphonics.
