I had a suspicion we knew each other, and getting in touch with him via email confirmed the story!
Josef and a few of his Scandinavian mates, all Hi Fi journalists at the time, actually DROVE to Paris for the HiFi show. That's dedication!.
Josef and I have different recollection of our first meeting and he might be right: Josef believes we first met at the Frankfurt Fair.
We made friends, had them for dinner at our place, and they presented us with a beautiful crystal vase, (which tends to confirm we had met before...) that actually survived the trip to Australia!
Josef ended up trying to market our products in Sweden and still have a pair that his daughter uses as computer speakers...Such is life!
We had more success in Norway with our friend Martin Viktorin now at Digital Audio Martin Viktorin, who flogged dozens of them to the Norway National Radio in their powered version.
