Brinkmann's 9.6 tonearm ($3990) resembles the German company's longer, more expensive 10.5 and 12.1 arms, which in turn resemble the legendary Breuer. The new arm includes the same headshell, armtube, mounting socket, and cueing device used in the other arms. The bearing system differs, though the Swiss-made ball bearings are identical.
While the more expensive arms use traditional fixed-gimbal bearings, the 9.6 has a unipivot-like construction for the horizontal bearing. The weighted arm housing sits on a small ball that rests on a pivot, also as in a typical unipivot design. A second ball at the bottom of the housing prevents "arm lean," but since the arm's weight rests on the top ball, the lower one isn't critical, and I could feel some play when I handled the arm. Vertical arm motion is effected via a second pair of captured bearings. This arrangement allowed the use of less costly parts and kept the price down, Brinkmann says. The arm's effective length is 248mm (231.5 from pivot to spindle, plus 16.5mm of overhang), while its effective mass, referenced to the center position of the headshell slot, is 12gm.
The Brinkmann Pi cartridge's Benz-Micro heritage was obvious from the get-go. The motor is built to Brinkmann's specifications by Benz-Micro and includes a Micro-Ridge stylus. The cantilever material is not specified. The Pi's output is approximately 0.25mV, and its compliance is moderate at 15µm/mN. Recommended are a tracking force of 1.82gm, a VTA of 23°, and a resistive load of 600 ohms.
Helmut Brinkmann says he tweaked the Pi's design for a year and a half before he achieved the results he desired, including making the tiny set screws out of various materials. The Pi, with a body of machined aluminum designed to control the dissipation of resonant energy, weighs a hefty 14gm. Brinkmann supplies aluminum screws and titanium washers, which, he claims, in combination with special damping between the cartridge body and headshell, have been "sonically tuned to create a unique musical instrument."
I won't debate here how to make a turntable's platter go around. Choose your favorite: belt vs direct drive, idler wheel vs belt, spring-windup vs wind power, whatever. As far as I'm concerned, there's nothing to debate. Each of these technologies has its pluses and minuses, but none can produce CD's accuracy of speed and inherent freedom from wow and flutter.
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.
