Stillpoints LP Isolator Record Weight

Watch out.
$550.00 is a large investment for the minimal improvement over other options.
There is a best of 5-10% reduction in vibration vs. an outer record clamp pure fact. The ring couples 100 times the surface area directly on the outer edge - around the record vs. a small locating diameter in the center of the record LABEL - center clamp or weight.
We shipped many center weights (6000 and counting)and we are the leader in center weight production and our best pure copper center weight - Yes Pure expensive copper 3.2 Lbs and sounds amazing.
We build a killer 2.2 lb stainless carbon fibre that will equal the stillpoints product for under $250.00 - and a 1 lb for $89.00 more reasonable and the Classic has been on the market since 2008 and is very effective and is the most common center weight out there today...
Buy an outer record clamp for a few dollars more and get 10 times the results of ANY center clamp/weight period.

We will post actual test measurements shortly!

Radioheadokplayer, had I know you had a Lenco, I would have known that as that is what I have also.

Assuming that you buy into the Stillpoints "technology," the LPI operates differently from other weights and clamps. The idea is that its five pyramidal bearing pockets convert vibration into mechanical energy dissipated as the heat of friction between the bearings. With this approach it should be possible to drain vibration without resorting to higher mass. I use it and like it.

At an audio show I experienced a demo in which an LPI was placed on top of the switching power supply of a headphone amp. After a few seconds background noise fell off and the presentation gained clarity. When the LPI was turned upside down (decoupling the bearing pockets from the interface) there was a lesser improvement.

Dgarretson, what one has with the Stillpoint technology is ceramic balls sitting on three same size ceramic balls that are spread just far enough apart to not allow the one on top falling through. This makes the vector of vertical vibrations almost entirely horizontal but this is restrained by a stainless ring, meaning it is turned into heat.

It's an interesting approach with the primary function of draining vibration from the spindle bearing area, and the secondary function of clamping the record to the platter. A heavier weight or clamp might be more effective at the latter, while less so at the former. A peripheral ring is probably better at clamping then any clamp, with the further advantage of increased flywheel effect contributing to speed stability. Maybe the best of all possible worlds is LPI for vibration in combination with peripheral ring for impedance matching and speed stability.
