One Stillpoints Ultra SS audio tuning isolation device in a very good condition. If you already have a set of three Ultra SS, you can use this one to make it a set of four. By installing Ultra SS under an electronic component you are effectively eliminating a direct path between the component and whatever surface it sits on and as a result you mechanically lower the noise floor. By doing this you increase dynamics, heighten transients, increase the amount of air and space resulting in a much more musical and natural presentation. Retail price is 300 euro for one Ultra SS.
