I've been recommended these to plug that gap after the TAD's...well the guy said they were simply excellent speakers. He's had plenty and apparently the drivers used a very special.
They are a crossoverless design with a proprietary driver that compares better to paper cone. I found this difficult to believe but apparently so.
Have asked some questions. The stand mount starts at 5k euros I believe and they do a twin driver model...
Only a few dealers at the moment in Germany, Asia and USA. Just wondered about getting a pair....might go and have a listen although the nearest place is 3hrs.
