Audio Replas's OPT-30 HG 20HR/4P (Set of 3)
Feet by Audio Replas
30x20mm type was released in Super High Purity High-response Solid Quartz series. Height was increased to 20mm from 10mm height of OPT30HG series, and the vibration-canceller power was improved. By increasing height and Mass, a capability to cancel vibration energy is remarkably improved. Super high S / N ratio, sound of full reality, smooth and openly, and worm as well ... ... no words to express it. This is the world's first insulator which can display 100% ability of equipment. Please do not mix up with other similar-looking products made by quartz, crystal glass, etc.
