As the Mk.II Model Seven loudspeaker differs only in detail from the original Model Seven, I refer you to the measurements sidebar that accompanied Michael Fremer's review for the overall picture. I performed only a few measurements on the updated version. Fig.1 shows its electrical impedance and phase, taken with the two pairs of binding posts in parallel. This is generally similar to that of the Mk.1, and, like that speaker, drops to a low value at the top of the audioband, particularly with the rear tweeter turned on. The minimum…

I performed a full suite of measurements on one of the Vandersteen M7-HPA amplifiers (serial no.107), using my Audio Precision SYS2722 system (see www.ap.com and the January 2008 "As We See It"). I preconditioned the amplifier by running it at one-third the specified power, 100W, into 8 ohms for 60 minutes. At the end of that time, its heatsinks were warm, at 112.4°F (44.7°C). The percentage of THD+noise at this power level was 0.07%.
A note on the measurements: the M7-HPA's hair-trigger protection caused it to shut down several times…

A lady walks into an audiophile bar (footnote 1). She sees four men. They all turn to look at her.
All the first audiophile sees is some lady in a bar. He thinks nothing more. Can't be bothered. Let's face it—how often do you even see a lady audiophile?
The second audiophile does acknowledge her—but only because he clearly believes he belongs to a higher class of intelligence. A seasoned pro, he impressively regurgitates specifications and facts. This mansplaining gentleman knows what ladies like to hear. But what might she like to hear? The question never…

Many people, after seeing him repeatedly at Manhattan's Forrest Hotel in the early 1960s, might have described the lyricist and songwriter Doc Pomus as the narrator of a Damon Runyon short story depicts himself: as someone "who is just around." Pomus lived for years in lackluster hotels like the Forrest, which Runyon himself had once called home, and his cronies could be just as colorful as Runyon's creations, including the gamblers—for a…
