to Mrtennis .I donot know when you were there but there was a problem with a modwright pre that took a lot away from the setup as a whole I heard them on the last day in the afternoon when everything was sorted and they just vanished in the room ,read all the other show reports out there ,they heard the same things I did . Roger sanders speakers are very clear they are electrostats they should be.the Nsr speaker can do several things better than stats
including tunefull bass ,imaging,and dynamics.The NSR Sonic D-3 is now in the production end and is noticable beter than the proto types at the show and please remember this was a $5k loudspeaker .they have a Reference Xover which are the finest parts in the world from Duelund and this transforms this speaker against anything at $10k I heard it recently while in New england for under $5500, and the Patented bass wil cleanly play any note of a concert grand Piano ,go to http://www.hifidelityaudio.com
and they can tell you more.
