I am actually pleasantly surprised. The 4367 had a rare ability to sound full, dynamic and detailed at the same time. There is something weirdly addictive to listen to a well designed horn covering 800Hz up with a bass driver that is up to the task to complement a compression driver. And it is not double the price. 20K is a good starting point for a second hand deal

I am excited, just waiting for the first pairs to arrive in Europe so I can go and have a listen.
