We welcome your questions and comments.  We assume they will be about our products—either before or after a purchase—and how to best use them in your music system.  You may also ask us for other audio advice, though perhaps you will get a wider range of answers at the popular and friendly AudiophileStyle.com forum.

Both John Swenson and myself—as "Superdad"—hang out there weekly and there are many other sharp minds among the active membership at AS.  There is also an UpTone Audio sponsored forum at Audiophile Style.  Please join us there.
Messages via the below form come to me immediately via e-mail, but can only be replied to if your correct e-mail address is supplied.  If you would like to receive a telephone call, then please include your phone number, location, and the best time to call. 

To request a quotation and/or to make a reservation for our very popular new JS-4, it is most helpful for you to include your complete delivery address and specify the device end plug size(s) for the SAPPHIRE DC cable(s) you wish to be shipped with the JS-4 (or tell us your devices and we can advise plug size). We will reply back right away to your reservation request and questions and can proceed from there.

Sincerely,
