AET AET Spike Base Black 3 pieces SH3009B-BK3 Brand new, unopened *Comes with 3 pieces. I am selling this because I no longer need it after purchasing it new. I am also selling this elsewhere, so you can buy it immediately, but I may remove it depending on the timing. [About Shipping] *It will take 2-3 days to ship. If you are in a hurry, please consult with me in advance. Thank you very much ^^ ■ Thorough high strength and low center of gravity Insulators for audio require high strength. If the strength is insufficient, the power and sense of positioning will not be established, and you will not be able to experience the true pleasure. The SH series uses a high-strength aluminum alloy as the main material and combines it with industrial carbon steel to achieve extremely high strength specifications. And in the spike, while maintaining strength, the height is about 1/3 compared to the conventional model, and the center of gravity is lowered, further improving sound quality. ■ Carefully selected and carefully selected high-quality materials It has the same weight as aluminum, but the same strength as steel, extremely fast vibration propagation, and less howling. ■ High-hardness surface treatment The contact point is closely related to vibration treatment. "HV700" is applied to the carbon steel at the contact point for thorough hardening treatment. The dramatically higher hardness compared to conventional surface treatments contributes to improved edge and speed. ■ Further evolved irrational number application design It is no exaggeration to say that the sound quality of the insulator is determined by "strength". The irrational number application design that achieves high strength has been further evolved and reborn into a new design with even higher strength.
