Minus
K is providing Audiophiles a new level of sonic transparency
Minus K's products have always added to the audio experience, but lately audiophiles have seemed to stumble on us again. Within the last few months five different magazines and online blogs have opened their ears while using Minus K's vibration isolators with their turntables, DAC, Blue Ray players and tube amps.
Here are a couple of excerpts:
"Wow! This is a phenomenal product that works as claimed! Our worst-case challenge is to isolate external vibrations from interfering with our turntable systems. Presently, we use three reference turntables: the Linn Sondek LP12 with Linn Radikal DC motor, motor control unit and power supply and Ekos SE tonearm with an Akiva moving-coil cartridge, and the Thorens TD 350 and Thorens TD 2035. The Linn setup is in Widescreen Review's reference system and the Thorens in a secondary, Class A system. Both setups are prone to vibration within a frame wood structure and concrete slab foundation. In fact, one must walk with extreme care to not cause the stylus to jump grooves. Thus, this was a perfect test for the BM-8."
"In both locations, with the Linn and Thorens supported by the BM-8, the stylus jump condition was completely eliminated! But the real benefit was the immediate sense of openness to the sound that was obviously previously masked by vibration and the seemingly complete absence of rumble and acoustic feedback. The BM-8 has no competition in this regard and is a MUST HAVE component in an enthusiast's system."
"We
also positioned the OPPO BDP-95 Universal 3D Blu-ray
Disc Player on the BM-8. While the sonic improvement
was not as dramatic an improvement compared to the
turntable performance, still a detectable nuanced
clarity in the sound resulted. The BM-8 is simply
an amazing vibration platform product that provides
an impressive degree of isolation from vibration distortions,
resulting is definitive sonic refinement. Recommended!"
- Widescreen Review
"This owner and a few others told me that the addition of the Minus K technology took an already amazing turntable to a whole new sonic performance level and that it also totally eliminated foot-fall based stylus-skipping issues, though that's not a problem in my concrete slab floor located listening room. "
"The sonic difference was "as advertised" to me by one of the Continuum owners: (among other sonic benefits) the blackness of the backdrop, which already was noticeably superior to any turntable I'd heard got even blacker and took the term "silence" to new levels. Another Caliburn owner was so impressed he bought a self-contained unit and put it under his DAC. He says it made an equally profound difference." - AnalogPlanet (Michael Fremer)

Product: The BM-4 can now handle payload up
to 200 lbs
Minus K has increased the range on our least expensive half hertz horizontal isolator which can now handle payloads up to 200 lbs. So we are now proud to introduce our new BM-4 models, the 150BM-4 & 200BM-4.
The BM-4 currently offers the smallest footprint for the 0.5 Hz horizontal natural frequency and our signature 0.5 Hz vertical natural frequency.
The 25BM-4 is the star of our famous wine glass demo that is on our home page

Minus
K Negative-Stiffness Vibration Isolators #2-6 Ordered
for the
James Webb Space Telescope
Minus K Technology, Inc. has received the order to provide vibration isolators, numbers two through six, for the ground testing of the new James Webb Space Telescope (JWST) at the Johnson Space Center (JSC). Minus K completed the order for the first of the six Negative-Stiffness vibration isolators in February 2012.
The JWST will be placed in a thermal vacuum chamber at the Johnson Space Center and supported by a set of six custom Minus K vibration isolators. "The isolators will utilize Minus K's new thermal compensator device, a passive mechanical device (patent pending), requiring no air or electricity just like our isolators." says Dr. David Platus, president of Minus K and principal inventor of the patented Negative-Stiffness technology. "The compensator will adjust the isolators as the temperature changes throughout the testing at JSC, keeping the JWST in the proper position."
The James Webb Space Telescope is a large-aperture infrared space telescope that has a large mirror, 6.5 meters (21.3 feet) in diameter and a sunshield the size of a tennis court. The JWST is planned to be launched from Arianespace's ELA-3 launch complex at European Spaceport located near Kourou, French Guiana. in 2018 aboard an Ariane 5 launch vehicle.
Minus
K Technology, Inc. works with many aerospace and education
laboratories for custom vibration isolation systems.
They have manufactured custom vibration isolators
for the Jet Propulsion Laboratory (JPL), German Center
for Aerospace (DLR), European Space Research and Technology
Centre/European Space Agency (ESTEC/ESA) in addition
to the JWST custom isolators for the National Aeronautics
and Space Administration (NASA).

the Minus K isolators will be used for Ground Testing)
