The Minus K Technology NASA-Grade Tabletop Vibration Isolation Platforms
Minus K Technology builds NASA-grade vibration isolation
devices for the scientific community. But audiophiles
have discovered that Minus K platforms make superb isolation
systems for turntables and other components-purely mechanical
devices that operate without electricity or air. Minus
K claims its platforms deliver "10 to 100 times
better performance than a full-size air table,"
yet take up much less space.
Best suited for audio applications are the BM-6 and BM-8 tabletop isolation platforms. The units are similar and offer identical 1.5Hz horizontal isolation, but the BM-6 provides 2.5Hz vertical isolation, while the more expensive BM-8 provides "true .5 Hz isolation" in the vertical axis. Both measure 4.6" x 18.6" x 20", and can be ordered to support loads of 25, 50, or 100 pounds. BM-6 models range from $1800-$1900, while BM-8s range from $2400-$2500. Minus K can provide custom versions that can accomodate oversized loads. minusk.com (check out Applications, Audio Reproduction)
