I was able to test Sorbosein Sound Insulator (SSI-001) as well as shooting, so I checked the product.
It is a high-performance insulator developed for audio by Mitsushin Kosan Co., Ltd.

It is a three-layer structure design supported by Sorbosein, a rubber material, on the base of a combination of gold-plated brass and ebony. SORBOSEIN is a material applied in various fields for the purpose of vibration prevention, vibration control, noise reduction, soundproofing, etc.
The appearance impression of the insulator "SSI-001" is the combination of ebony and gold-plated metal parts is luxurious. The price is 49800 yen. 。 It is a little small, but it can be said that it is usable size.
It can also be used for amplifiers and players, but it is sold in 3 pairs one by one because it is an audio base that improves the sound quality with the main speaker (there are also 4 pairs optional). So, if you use a speaker, you need two sets. 。
The brass of the material is non-magnetic, it is a metal with a moderate weight, good sound enough to be used in a brass instrument, it is a metal that does not have a habit of resonance. Ebony is a very hard, very resounding wood, this is also a high-grade wood used for musical instruments such as oboe and clarinet.
The height adjustment that can be fine-tuned with screw type is very effective for players such as turntables. What can not be missed is that the thin screw part that is connected to the base ebony has a pinpoint base effect that supports the point. And the receiver's ebony moderately prevents the resonant sound unique to the metal, and the 8mm thick anti-vibration material Sorbosein absorbs and disperses the overall vibration from the equipment on board without limitation.
This time, I listened to the verification of the effect obtained by it with turntable and speaker.
First, the turntable. Balanced on the hard bottom part 3 points. Because the magnet is not used, there is no need to worry about magnetism in the installation place.
It is a feeling that the outline of the sound has become clear whether it is said that the blur has disappeared due to the vibration control effect and the sound turbidity has disappeared due to the pinpoint effect. The vibration control effect of Sorbosein seems to create a considerable sense of stability for delicate operation such as tracing cartridges and reading CDs. However, in the SONY PS-X70 I tried this time, since the cartridge was the MM type of Gorigori, the change is calm, perhaps the effect is not quite high such as the delicate MC type with low impedance or the cartridge without damper.
The effect of the insulator was clearer than the speaker. The focus was fixed and the slight blur was lost. The outline of the sound becomes more clear, the clear texture extends to the bottom of the low range, and the sound tone without turbidity. Transparent, clear, soft stretching to high range, no piercing and cloudy, the sound is as different. The sound is very good and the sound is very comfortable.
The SSI-001 Sorbosein insulator, which brings out the best of the negative parts of the speaker, is an insulator that demonstrates true value for the speaker, and it is good to say that its value is well worth this price.
It is an item that you want to try if you want to pull out the performance of the speaker in full.
