Nagaoka INS-SU01 Audio Insulators 4-pack

Nagaoka INS-SU01 is a set of vibration-damping feet designed to reduce unwanted resonance and mechanical impact from the surface during playback. Placed under turntables, CD players, or other sensitive audio equipment, these insulators contribute to a more stable sound image with improved clarity, depth, and dynamics.

Each foot consists of a precision-turned stainless steel cone with a hard ruby ball at the tip. Ruby is almost as hard as diamond, and each foot can withstand loads of up to 100 kg. Together with the separate stainless steel base plate, this creates a point of decoupling from the surface that effectively dampens both internal and external interference.

The set contains four insulators – four cones with ruby balls and four corresponding base plates. Each cone weighs approximately 43 grams, and the base plate weighs approximately 23 grams. Together, they are approximately 29 mm high (23 mm cone + 6 mm plate) and have a diameter of 25 mm. Double-sided tape is included for those who want to attach the cones to the underside of the device for extra stability.

The result is a cleaner and more defined reproduction, especially in the bass and midrange, with reduced blurring from vibrations in furniture, floors, or the surrounding environment. In addition, your equipment gets a visual lift with the discreet and elegant design.

The INS-SU01 is an excellent choice for audiophiles who want to improve sound precision and give their components a solid foundation to play from – both technically and aesthetically.
