An audio cable maker, 47 Labs probably has the most awakened eyes on cables than any other maker. Cables placed in audio systems are nothing more than a necessary evil, and can only be evolved in an effort to reduce their existence. For 47 Labs, the evolution of cables is the "process to extinction", and 47 is a cable system that minimizes its existence to the utmost limit. 

Until now, the weight of the cable has rarely been a problem. But for 47 Labs, this is an important factor. The cable presses itself against the vibrating body (floor, wall) by its own weight, and the heavier the cable, the greater the impact of vibration received by the core wire.

Since the damping material that should isolate the core wire from vibration helps to increase the weight of the cable itself, not only the damping effect as intended cannot be obtained, but also the damping material releases the vibration energy stored in the damping material. Because it interferes, the change in the dynamics of the music is absorbed by the cable, and the rhythm does not stand. There is no effective way to break this vicious circle except to reduce the weight of the cable itself.

The 47 cables weigh only 5 grams per meter.
