I heard the Lipinski at the last CEDIA show and they were extremely good even under terrible show conditions.
I have also sold Avalon's in the past, I like Avalon but quite frankly the Lipinski was totally awesome.
I heard the Lipinski at the 06 CES. They were set up in a multichannel config. Very smooth. My impression is that full range was sacrificed for excellence in the range it does well at. Down to 40 essentially. Designed to image spectacularly. This is a speaker that I would buy with the given that a sub would accompany it. Perfect choice for a 5.1 with good bass management. This speaker was made by someone who knew what he wanted and new no one made it. And he has engineered his "ultimate". It's very good.
