Since the DBA-02 seems rather hard to get right now, this Russian webstore has them, among other Fischer Audio products, in stock. According to a Russian friend, the store is pretty well-known and trustworthy. If I understand the translation well enough, they ship all the way to whereever if needed but you have to contact them for areas outside of the greater Russia area. Prices seem very reasonable for the FA products. Cheapest around, it seems. Other brands are more expensive there but since FA is a Russian brand I guess that kinda makes sense. Go check it out!
