OYAIDE / INS-BD insulator

High-precision cut black diamond. Natural stone insulator.

Oyaide's hugely successful ""INS series"" centers around the multi-base insulator ""INS-BS,"" and has since released the hybrid carbon fiber ""INS-CF,"" the high-rigidity stainless steel ""INS-SP"" (concave type) and ""INS-US"" (convex type). By freely combining these, the series has successfully expanded the possibilities of insulators. These ""insulators that offer the joy of combination"" have been widely accepted by audio enthusiasts, and the series has achieved phenomenal sales of over 20,000 sets since its release (June 2009 - February 2013). It has come to hold an unshakeable position as an essential accessory for the feet supporting audio equipment. Seeking further possibilities for the ""INS series,"" we focused on the material properties of natural stone. The material properties are the most important tuning point in audio; this is a common design philosophy for Oyaide Electric's insulators. After examining the physical properties of over 70 types of natural stones and conducting repeated listening tests, we discovered outstanding performance and individuality in black diamonds and smoky quartz.



●These natural stone insulators are precisely cut at a domestic jewelry workshop and meticulously mirror-polished by skilled gem craftsmen.

●These are easy-to-use, coin-sized insulators compatible with INS-CF/INS-SP/INS-US.

●They can be used individually, or combined with the multi-base insulator ""INS-BS"" for even more tuning possibilities.

●They can be used not only as insulators but also as tuning chips by placing or attaching them to equipment.

●Please handle with care, as strong impacts or pinpoint pressure may cause breakage.

●Enjoy the unique texture and color of each individual natural stone.
