If you ever find yourself in an audiophile-type argument and need proof that, in the 21st century, manufacturing high-performance audio gear to sell for a reasonable retail price is becoming an impossibility, point to Vincent T.A.C.'s TubeLine SV-236MK integrated amplifier, designed in Germany and built in China.

This massive, two-box beauty from Denmark costs $60,000, and I wish I could tell you it wasn't really better in most ways than the already outlandishly priced and sonically superb Boulder 2008. I can't.

Trends in turntable design shift back and forth over time, each "advance" turning out to be a mostly sideways move. Over its long history, VPI's founder and designer, Harry Weisfeld, has moved the analog goalposts back and forth as he's refined his thinking. His early turntables were mostly standard spring-suspension designs of normal size. By the time Weisfeld produced his fully tricked-out TNT model, which was originally designed to stably hold the heavy moving mass of Eminent Technology's ET2 air-bearing arm, he'd moved to a massive, oversized, sandwiched plinth with isolating feet at the corners. He first used springs and, later, air bladders originally designed to cushion a tractor-trailer's load, and which he'd found in a trucker's supply catalog. Via an O-ring, the TNT's outboard motor drove one of three pulleys that protruded from holes in the plinth, and attached to a T-shaped subchassis that, in turn, drove the other two pulleys via two additional O-rings.

VPI Industries' Harry Weisfeld has tried, built, and marketed almost every known way of spinning a platter. He began in the early 1980s, before many recent turntable enthusiasts were born, with the belt-driven HW-19, and since then has produced rim-driven models, and 'tables with motors outboard or inboard, one or three pulleys, one or three belts, and platters of acrylic or aluminum alloy. But while Weisfeld has owned quite a few direct-drive 'tables, he'd never come up with his own—until now.

In 1995, Harry Weisfeld's son Jonathan was killed in an automobile accident. Jonathan was a charismatic young man whom I had come to know—a genuinely gifted artist and musician who, at the time of his death, was helping his father develop the tonearm that would be named for him: the JMW Memorial Arm. The design of the original JMW Memorial Arm focused on providing easily adjustable and repeatable VTA and SRA via a massive threaded tower that bolted to the plinth. The bearing point, on the other hand, sat near the end of a relatively long and not particularly rigid metal platform cantilevered off the VTA/SRA tower.

Prejudice is bad—whether it's directed at people, places, or things. You know how it goes: digital is "bright," analog is "warm," solid-state is "brittle and etched," tubes are "smooth and soft" dynamic drivers are "low-resolution," electrostats and planars are "high-resolution" copper wire is "smooth," silver is "bright," etc. While putting everything that crosses your path into one box or another makes life simpler and seemingly more organized, the truth, musical or otherwise, usually gets mutilated in the process. Not that we all don't have preferences—but those are not the same as prejudices.

Stop me if you've heard this one: Back in the early 1990s, just after the fall of the Soviet Union, I debated professor of music engineering and magazine columnist Ken Pohlmann on a talk show on the CBS radio network. The subject was analog sound vs digital sound, but I guess when Pohlmann felt I was getting the upper hand, he felt he needed to play the tube card. Derisively, he said, "I bet you're one of those tube guys, too, aren't you?" Before I could open my mouth, he continued: "You know, the Soviet Union's military gear, including the MIG fighters, ran on tube electronics, and look what happened to them!"

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.

Big tube amplifiers were once scary monsters reserved for those who didn't mind heavy maintenance, careful tweaking, and the occasional explosion. Blown tubes required replacing, preferably with pricey matched pairs, then biasing with a voltmeter. Optimal sonic performance required regular bias monitoring and adjusting, and because of current surges on startup, you had to choose between leaving the heat-producing monoliths on, or turning them on and off for each listening session, thus shortening the life of the tubes.

Leaving aside for a moment the fact that the Wavac SH-833 costs $350,000/pair—
