I'm somehow interested in this company, maybe somebody can tell me some more about them? I have two radios - Stradivari DW5422 and Amati DW5420 and it's seems strange that company with such good quality radios could just go bankrupt and disappear.
Except enigmatic information on radiomuseum.org, flyer "Grosse Radio-Eintausch-Aktion" with Stradivari on sale and model list there's not too much information.
You can write in German if you prefer, I'm still learning

Best regards
Piotr
