About

Music drives our passion to create.
Hours of daily listening in our Portland, OR workshop provide us with an invaluable perspective on our work.
Everything that we manufacture, from portable headphone amplifiers to interconnects and cables, is made to reflect not only our own demanding standards, but to reflect what we enjoy in both portable and home listening. We are music fans first, and craftsmen second.
As such, we constantly strive to make concrete and appreciated improvements to the state of personal audio with each product we develop. This method ensures that we all can experience the very best, wherever the music takes us.

What do we make?

COPPER 22 CABLEFIRST RATE CABLES

Each cable is selected for its sonic virtue.  Each element of its design and assembly is examined.  Audio perfection can be achieved if each detail is attended to from the first moment of creation.
