Strain-gauge phono cartridges are rarely made and seldom heard; for most vinyl fans, they are more myth than fact. Panasonic once made one, as did Sao Win, but those were decades ago. I've heard about those two models for years but have never seen, much less heard one.
As if he's not got enough to do building his extensive lines of moving-iron cartridges, preamplifiers, amplifiers, and speakers, Soundsmith's Peter Ledermann also makes a full line of strain-gauge cartridge systems available with a choice of six user-replaceable stylus profiles. I believe the Soundsmith is the only strain-gauge cartridge currently made anywhere in the world. Ledermann says it takes him a full day to build one.
Computers and vacuum tubes go together like Trent Lott and flyaway hair, right? The last time filaments glowed in computers was during the 1960s, when a computer was a building. I remember laughing at the ponytailed computer-science dweebs back then, who spent their college days playing nursemaid to a football field's worth of electronics capable of little more than adding two plus two. Chained to a computer half the day, as most of us now are, guess who had the last laugh?
Ron Sutherland has devised the Timeline, a device for testing the 33.33 and 45rpm speeds of turntables. It's housed in a disc of aluminum and Delrin that fits over the platter spindle. Turn it on, and an LED shoots a red dash of light at the wall (if there is one) behind your turntable. If the dash doesn't move, the speed is correct. If it drifts to left or right, you'll need to adjust the 'table's speed. Unless your wall has hash marks, there's a bit of subjectivity involved, and at $399 the Timeline isn't cheap, but Sutherland says he's not making much money at that price, and that it will take a lot of sales to recoup the R&D he's put into designing something as precise as he claims the Timeline is.Michael Fremer
The $3000 moving-coil (MC) PhD, available from Chad Kassem's Acoustic Sounds operation, is a monumental achievement that, for me, sets new standards for the cleanness and transparency possible in a phono preamp—and I've had a lot of experience with phono preamps.
In the early 1970s, Stereophile's founder, J. Gordon Holta man I used to describe, with all due respect, as having been clothed by the haberdasher to the homelesssaid that Audio Research's SP-3 tubed preamplifier was "the closest thing available, in fact, to the ideal straight wire with gain" ie, it would amplify the signal without editorializng in any way. Back then, the SP-3 cost $595. Today it would cost around $3500. But TAD's C600 dual-mono, solid-state, balanced preamplifier costs more than 10 times that: $42,000.
The "Want to make an easy $1,000,000?" e-mail wasn't a scam from Nigeria but an alert from Paul DiComo, late of Polk Audio and now of Definitive Technology, about a double-blind cable-identification challenge made by The Annoying Randi, a magician and debunker of paranormal events who goes by the name of "The Amazing Randi."
Monoblock power amplifiers seem to be moving in and out of my listening room faster than green-onion salsa from Chi-Chi's. Over the past six months I've had the Parasound Halo JC-1, the Halcro dm68, the Pass XA-160, the Musical Fidelity kW, and now these 300W (into 8 ohms), $4500-each beauties from Theta Digital. All of these amps sounded as different as they looked, which was no surprise; too bad the "measures the same, sounds the same" dogmatists remain open for business.
Record playback could have been designed to go from the inside out instead of the other way around. With most pieces of music ending louder than they started, doesn't it make more sense to end the side at the widest circumference, longest wavelength, least congested part of the groove spiral? Compact discs read from the center hole out, and they don't even have to.
