At Stereophile, we don't generally allow Mulligans—review do-overs. Usually, we take a second look at a product we've reviewed only when the first sample turns out to have been defective, especially if it was damaged in shipping—and we rarely do even that.

Peter Ledermann, founder and chief designer of Soundsmith, Inc., began his adventures in phono cartridges by reverse-engineering Bang & Olufsen's Moving Micro-Cross moving-iron cartridges for customers B&O had abandoned when it got out of the LP player business, and putting them into production. The B&O cartridges were of the direct plug-in variety; once they were no longer made, a worn or broken B&O cartridge would render a B&O turntable unusable.

Why am I once again falling down the rabbit hole of alternating current? A while back, I committed to listening to SMc Audio's AC Nexus power conditioner, designed by SMc founder Steve McCormack and distributed by dealer Hi Fi One.

Bergmann Audio (footnote 1) launched its first turntable—the Sindre, which featured an integrated tonearm—in 2008. The Sindre's acrylic platter and tangential-tracking tonearm both floated on air bearings; it had an outboard motor controller, a separate air pump for the air bearings, and cost $21,000.

Among the electrically connected, the phrase short circuit induces panic and horrific images of tripped breakers, blown fuses, acrid blue smoke, and melted circuit boards. Nonetheless, near short circuits are becoming popular among the analog set. Moving-coil cartridges of an inductance and impedance so low they're nearly short circuits are now more common, thanks to powerful neodymium magnets that help produce more and more electrical output from fewer and fewer turns of coil wire. Perhaps the most extreme example of this is the Haniwa HCTR01 Mk.II cartridge, which has an internal impedance of 0.4 ohm and an inductance of 0.3µH.

As I begin writing this column, I'm on an airplane on my way back from the funeral of David A. Wilson, founder of Wilson Audio Specialties. Two days before I left for Provo, Utah, came the news that my friend and analog mentor, Wally Malewicz, had died the previous day in Minneapolis, after suffering a massive heart attack. Immutable Music's Seiji Yoshioka, designer of the Transfiguration phono cartridges, passed away February 17, after a lengthy hospital stay.
