Nanotech Systems Japan


What happens when you disperse nano sized (1-100 nanometers) particles of conductive copper, silver, and gold in deep-sea shark oil? Well, you get a unique product that aims to fill in any uneven gaps with electrical contact points. Think spades, RCA, XLR pins, and Power plugs.

Nanotech Systems Japan has been developing products to improve audio, video, and even automotive experiences for some years now. Beyond the contact points, This company has also designed speaker and power cables with nano particles in a colloidal liquid, More on that in a minute, but first let’s see how this nanotech can be applied.

Well, it can be used for just about any electrical contact point. I started off using the silver nano liquid on my speaker cable spades. I was told this would effectively fill in any gaps between the spade and speaker terminal. I also found a use for the copper nano liquid when building power cables and power distribution centers. These nanoparticles (used sparingly) of precious metal ensure that full power transfer is occurring at contact terminals.

I encourage experimentation of application to various contact points in your system. It should be noted that these are enhancers, not cleaners. So beginning with a clean contact is a good start. One experiment I did was with a very worn and noisy guitar cable plug. The solder points were all intact, but for some reason the plug made a noisy connection. I applied the gold contact liquid to the plug and the intermittent noise ceased. Excellent, now to try it in my audio/video system.

As for sonic improvements, these products may indeed help in that area. I recommend that you apply and test for yourself.


After speaking with Nanotech Systems Japan, I was able to test out fully terminated power cable (Golden Strada) that had been treated with nano particles. Gold and silver nano particles are dispersed in a colloidal liquid, then applied to the full length of conductors in this power cable. In addition, an electromagnetic wave absorption material is also applied to this power cable for reduced interference. This nano liquid, when applied to the full length of conductors may prevent signal jumping -which I suspect is one cause of distortion. See my article on solid core copper vs stranded copper cables.

For my application (audiophile systems), I used this cable to provide power to my power distribution bar (Oyaide MT-UB). I also tested it directly connected to my power amplifier.

With the Golden Strada providing power to my entire distribution bar (which I built with nano copper enhancers) I found a sense of ease and flow to the music which seemed to emerge from a blacker (quieter) background. Initial impressions; Taught extended bass with imaging control. When connected directly to my power amp the Golden Strada truly excelled at bass control/extension and quiet backgrounds.

I especially liked the Golden Strada power cable for picture quality in film. When used for powering a Blu-ray player in my system directly, the contrast and depth of picture was easily improved.

While using other power cables to provide power to my Oyaide MT UB, I found the unique abilities of the Power Strada to shine through when directly connected to my system components. Experimentation is encouraged, and using more than one in an audiophile system will provide varied results – build your own or buy terminated.

Nanotech Systems Japan has created a whole line of DIY products, enhancers, and completed products to improve audio/visual systems. These products are also not excessively overpriced.  If you are ever in the Akihabara neighborhood of Tokyo, I recommend finding some shops that carry these unique science-based audiophile products.

The HiFiQC Method For Stereo Microphone Isolation

Recording music and sound effects with carefully placed stereo microphones can present some challenges. Since directional microphones are more sensitive to infrasonic noise, special attention should be taken when placing them in various environments. Wind, machines, automobile traffic, and footsteps can all cause rumble or noise to build-up and eventually reach your microphones. The low-frequency nature of these sounds can take up precious headroom in your audio recordings. While wind (blowing on the capsules) can be tamed with various foam enclosures (the W5D is my favorite for Schoeps) don’t forget to isolate mechanical vibrations from reaching your mics too. After trying elastic shockmounts alone, I devised 3-part system to better isolate my ORTF stereo array (also works for MS, XY, and Blumlein) from infrasonic disturbances .

To start, Rycote has a non-elastic suspension made of a super-strong thermoplastic called Hytrel. And unlike elastic, it won’t sag and eventually wear-out (so far, so good). After being impressed with a Rycote Invision suspension for a single Schoeps mic, I decided to see if a solution existed for isolating 2 Schoeps mics arranged on the UMS 20 stereo bar.

After some digging, I came across the Rycote portable recorder suspension and wondered if it might work since the weight of the stereo bar and mics was nearly identical to most portable recorders. As you can see from the picture above, this model easily supports and isolates the Schoeps universal stereo bracket with mics attached.

Using a microphone suspension is certainly one method to help prevent vibrations from reaching your mics, but what about infrasonic born vibration from foot traffic, cars nearby, or HVAC compressors. These disturbances can travel up your mic stand and into your microphone.

After experiencing issues from foot steps and traffic rumble, I worked on a solution to isolate the microphone tripod from the ground itself. Both Carbon Fiber and Sorbothane are materials known to dissipate mechanical energy. So, I settled on Sorbothane hemispheres attached to an equal diameter carbon fiber disc.  Sorbothane works best when compressed under a range of weight (depending on size and Duro rating of hemisphere). By choosing a durometer rating of 50 in the 1.5″x.75″ Sorbothane hemisphere, 7-14 pounds of weight on each tripod leg could be isolated.  And after adding some 8 lbs sand bags to my tripod, I was able to get the load heavy enough to make the Sorbothane hemishpere’s truly effective.

Lastly, but equally important is making sure your microphone cables do not transmit cable-borne noise to the microphone body. Carefully dressing your mic cables around the tripod is essential to preventing vibrations from reaching your mic. With the help of velcro cable wraps, you can neatly run your mic cables, but don’t forget to pay attention to where and how they are laid on the ground. In some cases you may need to isolate the cable on the ground too.
