Original version of this well regarded upgrade. Super clean and complete with bearings, please see our photos. 6Moons review here: https://6moons.com/audioreviews/symposium/1.html More from Symposium: Introduction Symposium Rollerblock Series 2+ is an equipment support system providing simultaneous coupling and decoupling of audio and video equipment. When properly installed, Series 2+ Rollerblocks will enhance overall system performance, sometimes by an order of magnitude similar to a wholesale upgrade of the component it treats. The Rollerblock, first invented and introduced to the audio world in 1997 by Symposium, has for over twenty years been widely copied by numerous "also-ran" imitators, with new imitation products introduced on a seemingly never-ending basis. Points, isolators, footers, all with balls of some type in them have become ubiquitous, but none are as neutral or as resolving as the original, genuine Rollerblock® system. Utilizing technology employed in earthquake protection and combining it with proprietary mechanical transmission techniques, Rollerblocks offer extraordinary results at a reasonable price, usually outperforming other footer devices which sell for double or triple their cost. Used beneath digital equipment, DVD players, preamplifiers and other components, results can be nothing less than astonishing. Increased focus, soundstaging, image stability, dynamics and delicacy are just a few of the sonic delights awaiting the serious audiophile. When used on an appropriate and non-resonant equipment support (such as Symposium Platforms), the Series 2+ Rollerblock system provides an additional step toward ideal equipment support, which is simultaneous component isolation and drainage of chassis-borne vibration. Symposium Rollerblock Series 2+ systems achieve their seemingly "magical" results by obeying laws of physics. Their strict manufacturing tolerances (much higher than usually found in an audiophile "tweak" device) are responsible for their world-wide reputation as the best ball-bearing isolation device available. Professional reviewers and private owners alike have spoken emphatically about the ability of Rollerblocks to enhance and improve the performance of virtually any component, including CD players, DVD players, digital transports, preamplifiers, amplifiers, and more.
