KRIPTON's spike receiver insulator, the IS-HR3. Thank you. High-performance insulator with a hybrid construction of "Neo Fade" carbon matrix three-layer material and high-quality stainless steel, known for its high sound quality. The "Neo Fade" carbon matrix three-layer material accelerates the speed of sound of vibrations with carbon materials attached to the top and bottom, propagates them at high speed as surface waves (transverse waves), exchanges that energy with Neo Fade for heat, and smoothly absorbs the vibrations. This damping characteristic shows a clear difference when measured compared to conventional materials. ● Spike receiver compatible Can also be used with large floor-standing speakers with spike feet ● Uses the ultimate non-slip "O-ring" Special silicone rubber O-rings are embedded on the top and bottom to achieve the ultimate non-slip effect, especially the adhesion to the bottom is outstanding Surface panel: "Neo Fade" carbon matrix three-layer material Body: Stainless steel Non-slip: Special silicone rubber O-ring Size (outer diameter): 40.0Φ x (height) 11mm Weight: 95g/piece Set of 4 HR hybrid insulators that achieve high-resolution sound quality improvement. - Brand: KRIPTON - Model name: IS-HR3 - Type: HR hybrid insulator - Country of manufacture: Japan - Quantity: Set of 4 Thank you for viewing.
