Borresen Acoustics Speakers - Have you heard them & what did you think?


Borresen Acoustics have recently launched three models of loudspeaker.   The chief designer is ex-Raidho Acoustics.  Just wondering whether anyone heard or auditioned them and if so what were your impressions?  When commenting please let us know what loudspeakers you have today as this provides a useful point of reference.

I was the first to get the supreme titanium feet in the 03's and IMO that was a upgrade huge. When I ordered the 03's the titanium feet were not even an option but pushed Mike and Lars to do it. In fact at the time the titanium darkz were still only prototypes. Honestly if you can afford it go for the supreme titanium feet. Also if you look at current price sheets the non titanium feet are not being offered anymore for they are out of production.
What minimum amp power would you recommed to drive them perfectly ?Is 175w into 4 ohms enough ?
