The success of EtherREGEN—and user questions about it—has resulted in a large number of e-mails daily. To assure a timely reply to your inquiry we ask that you please keep your message short. Answers to most questions about the product can be found in the clear User Guide. And on the UpTone forum you will find answers about usage of EtherREGEN with many music servers/streamers/DACs.  We thank you for understanding and wish you good health and great music in 2024!

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. 

Sincerely,
