If you are in a hurry, please consult with me in advance. Thank you very much ^^ About AET SH-3009S Thorough Strength and Low Center of Gravity Insulators for audio equipment require high strength. If the strength is insufficient, the power and sound localization will not be stable, and you will not be able to experience the true enjoyment. The SH series uses a high-strength aluminum alloy as the main material, combined with industrial carbon steel, to achieve extremely high strength specifications. And the spikes have a low center of gravity, with the height reduced to about 1/3 compared to the conventional model while maintaining strength, further enhancing sound quality. Thoroughly Selected High-Quality Materials The high-rigidity aluminum alloy used for the body is a custom-made product from a domestic material manufacturer. It has the same weight as aluminum but the same strength as steel, extremely fast vibration propagation, and less howling, making it a wonderful material.
