All this verbiage is describing brute force, which we might use to push open a heavy door. But there's another kind of force that we encounter in the world, and consequently in audio, captured in the expression "life force." It denotes a sense of vitality and presence that isn't readily perceived by the senses—something lingering just out of reach of our rational minds. This force can be experienced in the terse saxophone solos of the young Sonny Rollins, the eerie abstract paintings of Mark Rothko and Pat Steir, and the deceptively quiet poems of Elizabeth Bishop. If you've ever been drawn in by one of the squat, gouged, lopsided jars made by a traditional Japanese potter, you know what I'm talking about.

When Ken Fritz died, many people wondered what would become of his stereo system. Fritz's rig was the stuff of legend. The audiophile from Chesterfield, Virginia, had built much of it with his own hands, including line-array speakers too tall to fit in most people's homes. They took 5400 hours to complete and were appraised at more than $200,000. He also designed and built a three-arm turntable that sat on a unique 1500lb antivibration platform. Fritz felt that his "Frankentable" rivaled or bested record players costing well into six figures.

That was just the beginning.

What can you get for $4750? A lot, apparently.
