47 Laboratory specifications

The company 47 Laboratory was founded in 1992 by Junji Kimura (Japanese surnames are prefixed, hence Kimura Junji). Amplifiers, CD drives and DA converters, speakers and cables, as well as turntables, phono amplifiers and pickups and arms are now developed and manufactured or distributed under the brand.

The choice of the company name can be described as rather unusual (according to the FaQ on the homepage):

What does "47" mean?

The surname of the founder is Kimura. "Ki" means yellow, "mura" (in Murasaki) means violet or purple in Japanese. As a color code on electrical resistors, yellow has the number 4, and violet has the 7. Therefore, 47 stands for Kimura.
