Heard them at the Danish HiFi show. They together with Radiant Acoustics 6.2 and the small Genelecs killed all the big and expensive ones.
Buchardt e50 reviews
Looks like the first review is out. Very positive. I've been interested in the Buchardt E50 speakers (and the March Audio Sointuva AWG). I'm a bit surprised the reviewer hadn't heard of Sointuva (a commenter asked about this).
