47 Laboratory

47 Laboratory Origins

The origins of 47 Laboratory, an audio company, can be traced back to its founder, Mr. Junji Kimura. The name “47 Laboratories” is derived from the Japanese language, where the number “4” is represented by the color yellow, pronounced “ki,” and the number “7” is represented by the color purple, pronounced “mura(saki).” Combining these, the code “47” translates to “ki-mura,” which is a play on the founder’s last name, Kimura.


The company is located in Kichijoji, a town in suburban Tokyo, Japan. 47 Laboratory is known for its unique approach to audio design, often incorporating unusual twists into its products. The company’s product lineup includes the 4704 PiTracer CD Transport, 4705 Progression DAC, 4706 amplifier, and the “Essence” prototype speaker, among others.


47 Laboratory’s products have been praised for their sound quality, with the reference system being described as having definite imaging, proper soundstage, and good timing. The company’s focus on innovation and unique design has set it apart in the audio industry.


As of my knowledge cutoff, there were rumors of a new “ceramic-boxed” speaker in development, although it was not listed in the company’s current catalog. The company’s products are available through local distributors and dealers, who can also arrange factory tours for interested visitors.
