Vandersteen Model 7: has anyone heard?

The Sevens were on demo at Ultrafidelis in Milwaukee all last week. That's a five hour drive each way for me and I was unable to make it. Anyone get a chance to check them out there? I need to hear them sometime. It's hard for me to imagine sound dramatically better than my 5As produce. For the money, this is likely the place for me to stop. Still, never say never.

I've never heard or seen the 7s but this lean bass observation puzzles me. I've had the 5As for about six years now and lean bass has never been an issue. Bass is actually a strong point. Tight, firm, strong and well defined. There is essentially no difference in the bass module used in the 7. It's one of the few things with very little change over the 5A. I suspect the guys here postulating less than optimal setup are on the right track to explain these scattered observations.
