Welcome to UpTone Audio.

We design and manufacture unique equipment and devices for enhancing your computer-based audio system.  The products we build are based on solid engineering combined with high quality parts and accessories.  Produced in the U.S.A., each piece is carefully tested prior to shipment and warranted for 3-4 years.  

UpTone Audio products result from combining the circuit designs of the respected engineer John Swenson, with feature selection, fine tuning, and production by life-long audiophile/music lover Alex Crespi (co-founder of the former Hovland Company, 1998-2009, and known on audio forums as "Superdad").

The products you see here deliver immediately audible benefits. The reviews we receive are overwhelmingly positive. We sell directly to audiophiles worldwide, and provide responsive pre- and post-purchase support. Perhaps one or more of our quality components will find a home in your music system. Please take a look around and contact us with any questions you may have.

UpTone sponsors a forum at ComputerAudiophile.com, one of the very best resources for learning and sharing about adventures in computer audio.  Please join us there.

Thank you for visiting.
