Marten is a small Swedish loudspeaker manufacturer with great aspirations, some of which the company has largely met. Leif Mårten Olofsson founded Marten and designs the speakers, while brother Jörgen Olofsson runs the business as CEO—a division of creative and administrative labors similar to the working relationship between David and Norman Chesky, the founders of Chesky Records and HDtracks.

Are you old enough to remember when the wires connecting speakers to even the most expensive and sophisticated electronics were 16-gauge, multistrand lamp cord, and the terminals on speakers and amplifiers were just little screws? Sometimes those screws wouldn't even secure all of the wires' strands, but as long as loose strands from one screw didn't touch loose strands from the other, it was good enough . . . and back against the wall went your bookshelf speakers.

Nuvistors—miniature, small-signal, vacuum tubes made of metal and ceramic—were introduced by RCA in 1959, at the dawn of the transistor revolution. RCA used them throughout the 1960s in its New Vista line of television sets, mostly in the tuner section. But by the early 1970s, solid-state devices had all but replaced tubes, nuvistors included (with a few notable exceptions). Ampex based the electronics of its well-regarded, late-'60s MR-70 open-reel tape deck on nuvistors, which were also used in microphone preamplifiers—in both cases for their very low noise and reputation for reliability and long life. For a time, Conrad-Johnson used them as well. While nuvistors may seem exotic today, they're hardly rare. On eBay you can find for sale hundreds if not thousands of used and new-old stock (NOS) nuvistors, as well as nuvistor sockets, without which the tubes are less easy to implement. (But they can be, and often are, hard-wired into a circuit.)

Pear Audio Analogue's Peter Mezek can keep you up all night spinning fascinating turntable tales. Had my mind not been numbed by Sunday evening, October 12, the last day of the 2014 Rocky Mountain Audio Fest, I might have insisted that he do just that.

Over dinner that evening he regaled Pear Audio's North American importer, Michael Vamos of Audio Skies, and me with turntable stories dating back to the late 1970s and the Linn Sondek LP12, which, until the early '80s, he distributed in Czechoslovakia. In the mid-'80s, Mezek was involved in the development and distribution of the Rational Audio turntable, designed for Mezek by Jirí Janda (pronounced Yeerzhee Yahnda), who died in 2000. For those of you old enough to remember, Janda, a founder of NAD, designed that company's 5120 turntable; among other features, it had a flat, flexible, plug-in tonearm that you could easily swap out, much as you can with VPI's current models.
