I agree with 'Infinite', Magnepan, started by Audio Research almost 30 years ago, hardly qualifies as secret.
A recently reborn company, (after a tragic flood almost took them out forever is making a big comeback) which was never an advertiser of any amount previously, and never had a very large dealer base, is Von Schweikert. I'll bet that very few of the (my fellow) audio nuts out there, have even heard them. Recently they've gotten some well deserved good press. Worth looking into for sure. Musical is the word to describe them. And, after all, colorations aside, that's what were all looking for: i.e. do they sound like music? Nothing does, but they are closing that gap. By the way, Sound Labs, is in about the same category. Not for everyone given their size and price, but excellent, excellent speakers, owned by the epitome of class, Roger West. He is a good man too, and takes wonderful care of his customers.
Good Listening,
Larry
