$0LD!!!Up for grabs are two sets of Symposium Acoustics RollerBlock Jr. HD-SE version. Each set includes eight (four upper & four lower bodies) and four, 1/2" Grade "10" Tungsten Carbide balls. These are considerably better than the standard Roller Block Jrs. I am liquidating these due to the dismantling of my second system due to a new home purchase and subsequent move...
They are constructed as described below...
1) Top grade 7075 "aircraft" aluminum alloy body. 7075 aluminum is harder than some steels and provides superior Brinelling capacity (resistance to denting and deformation despite extreme pressure) and superior mechanical coupling to even high quality 6061 alloy.
2) Special "Hard Coat" anodized body and cup area. Hard Coat anodizing provides a thin, precision skin of ceramic-level hardness which constrain-layer damps the HDSE body and retards wear in the cup area. This is the same coating used in the Series 2 RollerBlock body.
3) Tungsten Carbide is the best material for use in ball bearing isolation devices; Grade 10 means that each ball meets or exceeds a sphericity and diameter tolerance of 10 parts per million, which is 2.5 times better than the best "off the shelf" ball bearings available.
4) HDSE was originally developed for use with heavy loudspeakers (HDSE was first introduced in the Symposium Panorama loudspeaker), but is ideal with ALL components, both active and passive, and can be ordered in sets of 3 or 4. HDSE offers higher resolution and enhanced bass performance over standard Jr. versions in non-loudspeaker applications such as digital players, analog turntables, preamps, amps, power supplies and conditioners, etc. For best results, HDSE Rollerblocks should always be placed directly under the component and in contact with the component's chassis (bypassing the attached feet), unless the component has a specially tuned suspension system. This is because a great part of what they do, in additional to providing nearly perfect lateral isolation at low frequencies, is provide superior coupling and energy drainage (resonance damping) throughout the audible range from the component to the support structure or dedicated "shelf."

Also available are two more sets of four Tungsten Carbide balls in case you might want to only use a lower body half with one ball...Yes, I and others have tried this...these are priced separately, which is to be determined shortly.$0LD
