What are insulators?

Look up "insulator" in the dictionary and you may find definitions such as "nonconductive materials" or "ceramic bushings".
In audio, the word "insulator" refers to pads that block vibrations.
Insulators are installed between audio equipment and its contact surface, such as between the floor and speakers. It not only reduces vibrations, but it also cuts low-frequency noise transmitted to the audio equipment via floors and racks. Speakers are always creating vibrations. If they are placed directly on the floor, the energy will travel to other audio components, muddying the sound and ruining the sound color balance. Therefore, it is essential to minimize transmission of vibrations to the floor.
Insulators made of metal, rubber, glass, wood, brass, and many other materials are available on the market, in a variety of shapes.

Requirements of insulators

  • It must be strong enough to firmly support and stabilize the equipment.
  • It must not produce any sounds of its own.
  • It must effectively attenuate vibrations and improve sound quality.

As described above, Adamand Namiki’s ultra-pure monocrystalline sapphire has remarkable strength and hardness. The regular crystalline structure also makes for an ideal insulator material.
Our sapphire insulators are especially tight in the low range, clear in the mids and highs, and improve localization of the sound image in the mid to high range.
For example, when listening to classical music with our insulators in place, the sound of each instrument becomes well-defined, reproducing the concert-going experience.

Sapphire insulator

We had serious record enthusiasts try out our products.

This is what they had to say.
  • At first glance, it looks like glass, but the precision of the surface finish is incredible. They fit so perfectly; it is like there is an attractive force holding them together.
  • The ambiance of the silent parts has changed.
  • You can actually space the space inside of the recording studio!
  • The clearness of the sound is amazing.

Use as turntable sheets

The insulators can also be used as turntable sheets. Place 3 or 4 sapphire insulators evenly on the turntable, and the record on top of them. The sapphire will dampen vibrations and noise coming from the platter, and also add a sound you can only get from sapphire. Tune it as you wish and enjoy creating your own sound.

3-point vs 4-point insulator placement and vertex location

Our insulators are available in sets of 3 and sets of 4.
Sound characteristics differ between 3-point and 4-point insulator set ups.
Please choose the set up that best meets your needs.
The most frequent question regarding insulators is whether to use a 3-point set up or a 4-point set up. Generally, we recommend using a 3-point set up, unless the center of gravity of your component (such as amplifier) is significantly biased due to the location of the power transformer, in which case a 3-point support could cause instability. Otherwise, in a 3-point set up, the weight of the component can be equally distributed across the 3 insulators, keeping the center of gravity secure, and the sound stable.

When using 3 insulators to support and isolate an audio component, you must decide where to put the vertex of the insulator triangle. In the case of speakers, if two insulators are placed at the front and one in the back, the sound field tends to expand to the left and right. If one is placed at the front and two at the back, the sound field tends to gain depth towards the front and back. Two in the front, one in the back set up is the most common, and provides great stability. For amplifiers, CD players and other components that have power transformers, the two insulators should be placed on the side of the transformer to support and counteract the weight of the transformer. If the location of the transformer is not known, it is still common to place the insulators on the heaviest edge of the component. For safety, 4-point set up is recommended for large speakers and other components that would benefit from 4-point support. We recommend trying various layouts and finding the arrangement that you enjoy the most.

Craftsman's voice

The insulator must make good contact between the audio equipment and the installation surface, supporting both sides. Therefore, the surface of the insulator must be as flat as possible. We have expertise in ultra-flat polishing technology used for optical sapphire lenses that achieve flatness of less than 1λ.
By applying this technology, we are able to create insulators that effectively support both surfaces.

How to use insulators

Insulators are placed between the feet of each audio component and the playing surface.
