The VTL MB-450 series began life in the late 1980s as the Deluxe 300, a pair of which I once owned. Over the years the basic design has been improved and modified, in the forms of the MB-450 (1996) and the MB-450 Series II (which I reviewed in January 2008). The tube complement remains the same: eight 6550s in the push-pull output stage, a 12AT7 input tube, and a 12BH7 driver. Into a 5 ohm load, the MB-450 III is claimed to produce 425W in tetrode mode or 225W in triode, from 20Hz to 20kHz.
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.
Don't have $80,000 to drop on dCS's four-component Scarlatti SACD stack that I reviewed in August 2009, or $17,999 for their Puccini SACD/CD player that John Atkinson raved about in December 2009? Even if you do, the new Debussy D/A processor ($10,999) might be a better fit for your 21st-century audio system. Sure, you don't get an SACD transportor any kind of disc play, for that matterbut the odds today are that you already have a player you like that's got an S/PDIF output that can feed the Debussy.
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 old Saab slogan, "Find Your Own Road," was so good that the old General Motors, which once owned Saab, had to kill itjust as the newly revived GM tried, in a "Call It Chevrolet" memo, to kill "Chevy." GM did a U-turn on that one the very next day, but "Find Your Own Road" never returned, and is available for Ayre Acoustics to use. I can't think of a better slogan for a company that I admire almost as much as I do Saab.
Consider this: While Ayre calls its new DX-5 ($10,000) a "universal A/V engine," the disc player doesn't have a coaxial or a TosLink S/PDIF input. That appears crazy to me, but to Ayre, no. They've found their own road.
Show a time traveler from the 1920s an iPad and most likely he'd neither know what he was looking at nor what it might do. Show him a loudspeaker, even one as advanced as Magico's new Q5 ($59,950/pair), and he'd probably know exactly what it was and what it did, even if what it's made of might seem to have come from another planet.
Ideally, LPs should be played with the pickup stylus remaining tangential (ie, at a 90° angle) to the groovejust as the lacquer from which the LP was ultimately stamped was cut in the first place. Over the years, many attempts have been made to accomplish this. Back in 1877, Thomas A. Edison's original machines tangentially tracked his cylinders, but Emil Berliner's invention of the flat disc put an end to cylinders altogether. In the 1950s, a number of companies marketed so-called "tangential" trackers that used dual arms, based on conventional pivoting arrangements, to change the angle at which the headshell was mounted as it moved across the LP side. In 1963, Marantz introduced the SLT-12, which used a plastic pantograph to move the stylus across the record surface. Garrard's Zero 100 pivoting arm controlled its independently pivoting headshell with a bar that extended from the main bearing of the tonearm.
It doesn't take a genius to appreciate the audacity of naming a company after Albert Einstein, the iconic science and math whiz. Clearly, company founder and owner Volker Bohlmeier knew what he was doingthis German brand of boutique electronics has enjoyed worldwide critical and marketplace success since its founding more than 20 years ago.
Despite predictions to the contrary, the Compact Disc isn't dying anytime soon. Too many are in circulation, and until a smooth, friendly skin covers the computer interface, the music-server revolution will remain nascent. We're still in a long, shaky period of transition.
The minuscule electrical output of an analog signal from a moving-coil cartridge needs to be boosted before it can be converted to digital and equalized in the digital domain. Of course, you could use your current phono preamplifier and record an equalized signal to hard disk, but then you wouldn't get to experience Pure Vinyl's digital RIAA correctionnor would you be able to avail yourself of all the equalization curves provide by Pure Vinyl, of which there are almost too many to count.
