Stereolab named global sales partner for Concert Fidelity

Concert Fidelity of Karuizawa, Japan and Stereolab, LLC have come to an agreement to make Stereolab the global sales and marketing arm for Concert Fidelity’s expertly hand-crafted line of tube electronics. This arrangement has grown out of a long-term friendship and mutual admiration between Mr. Masataka Tsuda of Concert Fidelity and Chris Sommovigo of Stereolab (Black Cat Cable). “Tsuda-san‘s designs, and more importantly the perfectionist execution of his designs, have always impressed me quite deeply,” shared Mr. Sommovigo. “Over many years I have come to respect and admire him, and can attest to the truly special nature of his creations. To own something made by Tsuda-san’s hands is a privilege, in my opinion. I’m truly honored to be working with him.”

Concert Fidelity electronics are designed and built by hand in Japan by Masataka Tsuda in the best artisan traditions of that country, with a perfectionist’s fanatic attention to detail and a purist’s pursuit of optimized simplicity as the means of achieving the most musically authentic results.

Stereolab, LLC is the parent company of Black Cat Cable, which produces small-batch, artisan-made audio cables designed and manufactured by Chris Sommovigo, a veteran designer in High End Audio for nearly 30 years.

Stereolab, LLC is the global point of contact for all sales inquiries from international distributors and dealers who may be interested in the Concert Fidelity line.
