I popped in to this room as I was thrilled to see these big wooden horns on the dc10audio Berlin stand mount speaker. I was also amazed at the clarity and realism of the sound they were producing in-fact I was having a real moment with this gear when all of a sudden Robin? popped the tubes out of the tektron amplifier and Destroyed my moment! I left peed-off tried to get back in again but the room was fully packed every time I tried to finish my listen.Too bad for them. The Berlin was my favorite speaker at the entire show even though my bliss lasted for only 40 seconds. I think this company is really innovative as the horn is both the tweeter and the bass port and there is some kind of vibrator inside (kinky). I'll be looking for a dealer here in LA to procure the Berlin as I'm sold on it ..But shame on the Carnies at the show!!
