A high quality turntable will normally have a floating tonearm system however there can still be the need to isolate the turntable base from its support structure.These small pyramids are designed to do just that – provide isolation between the turntable and its support, especially useful in areas where there is likely to be foot traffic near or around the turntable. Sounds weird because you would think that once the vinyl is playing, the listener just sits back and enjoys it however in our previous studio environment, often the sound engineer would be moving about the studio to make adjustments to the outboard audio processing equipment and there is nothing worse than hearing external extraneous sounds being superimposed on the vinyl playback (we were involved in audio archival transfer work)These were sourced from Germany4x small pyramidsTotally rubber construction – hollow inside, stepped/terraced internally to give added strength to the pyramid.The rubber is semi-rigid, totally unlike plastic – when pressure is applied to these pyramids, they absorb the force but do NOT collapse, even with a heavy turntable system sitting on top.These could also be used with small bookshelf speakers although the pyramid footprint is pretty small.All black so that the isolation feet are discreteEach measures: 19mm height35mm length of each sideWe have just the two sets of 4 each set, no more after they have gone
