About Us

“Our mission is the design and manufacturing of the best possible audio electronics. The designs are as simple as possible, but not simplicistic — a difficult exercise!”

Our History

RudiStor Sound Systems was created in Italy in 2003 by Dr. Rudi Stor. From 2004 the company's activity has been focused on headphone amplification, but we have been designing and producing phono stages, power and integrated amplifiers, DACs, audio cables and professional studio electronic devices as well.

Since August 2006, “RudiStor Sound Systems” and “RudiStor R&D Labs” are trademarks of Audio Research Alliance LLC, located in Wilmington, DE, USA.

Prototype design and custom production are made in our R&D lab in Trieste, Italy. Standard production is carried out by highly professional labs in Europe or in the US under our strict supervision — and every single product must pass through our lab for final tests, tuning and approval before shipment. All production involves a large amount of hand work, and all products are individually tested. Quality is a must.

A Proudly Independent Company

We are no part of any trust of manufacturers, nor member of the board in any “forum”, or supported by any online or paper magazine. We don't ask for any “guided” reviews.

Our mission and philosophy are very simple: to design and manufacture the highest quality audio electronics circuits, with as few compromises as possible, and with no prejudices on components or circuit topology at all — in order to reach the highest quality of sound, and, the most important aspect, a genuine life-like audio experience.

We are not focused on designs or production to compete with other manufacturers: to be “better than” is not inside our goals at all. Our main target is to be “as good as” real life sound.

All of our design and manufacturing staff have, in one way or another, direct experience in music — playing instruments, being part of a group, or working in recording. And as a company policy, at least one live concert a week must be on our agenda: although we work in a technical and scientific field, we keep close contact with real music, with art itself.

How We Build

We buy components directly from manufacturers, or through important distributors that assure “first hand quality” initial selection dedicated to their best customers. But that is not all: after this, the components must pass our extremely demanding and selective tests. Many components are made according to our own specifications, and 90% of our internal cables are heavy silver plated.

To reach our mission we dedicate many hours and resources to research and development in our lab, and all of our products result from our original designs — many of them incorporate innovative solutions of which we are proud.

Twenty Years of Evolution

From the first RP-3 in 2003 to today's RP3K-SS, NX-03 and RPX-308, every RudiStor product belongs to a continuous line of evolution. We never re-issue an old model — each generation is replaced by a genuinely better one, and the retired models remain part of our story.
