A Home for RudiStor

If you ever owned a RudiStor amplifier — or ever wanted one — you probably noticed that at some point the lights went out. Emails to info@rudistor.com stopped being answered, and one day the website itself was gone. This site exists because of that silence. It is built and maintained by a long-time admirer of Rudi's work, as a permanent archive for every RudiStor product: the descriptions, the photographs, the specifications and the prices, gathered from web archives and preserved in one place, so that twenty years of remarkable engineering are not lost.

What happened to rudistor.com

Here is what the public record shows. The official website was essentially frozen from 2018 onwards — the pages stopped changing, and no new products appeared. The last archived snapshot of the genuine RudiStor website was taken on January 25, 2020. After that, the trail goes cold: by late 2023 the domain was only answering with a redirect, and from 2024 the name rudistor.com was picked up by an unrelated operation that has nothing to do with audio. The original site, and the company behind it, simply vanished from the web.

What happened behind the scenes, nobody outside Rudi's circle can say with certainty. Fellow enthusiasts who met him at shows and followed the brand for years report that Dr. Rudi Stor retired and closed the company, and that since around 2021 he has been unreachable. We have no reason to doubt that — and no way to confirm it. If you know more, we would genuinely like to hear from you.

Update, November 2026: the rudistor.com domain has found its way back — it is now in the hands of a fellow RudiStor enthusiast, and it points here, to this archive. The historic contact address info@rudistor.com is reachable once again. The spam site that briefly occupied the name is gone for good.

What this site is — and what it is not

This is an unofficial, fan-built archive. It is not the resurrection of a store: nothing here is actually for sale, and this site has no connection with Audio Research Alliance LLC or with Dr. Rudi Stor himself. All RudiStor trademarks and all original texts and photographs remain the property of their respective owners; they are reproduced here in good faith, for preservation and documentation only.

What you will find here is the most complete record of the RudiStor catalogue we could reconstruct: the current line-up as it stood when the site went silent, and a Product Timeline that follows every family of amplifiers from the first RP-3 in 2003 to the last models of the 2010s — including the retired ones, because each of them is a chapter of the same story.

In memory of a remarkable run

RudiStor was a small, stubbornly independent company: no investors, no review samples traded for praise, no compromises dressed up as features. Every unit passed through the Trieste lab for final testing before shipment. For almost two decades that was enough to build a loyal following around the world — the kind of following that, years later, still runs listening tests of an RPX-308 and still asks "does anyone know what happened to Rudi?"

This archive is our answer. Wherever you are, Dr. Rudi — thank you for the music.
