I heard these speakers this morning--5/17--and had my socks knocked off. The definition, the clarity is incredible at all volume levels. Deep, tight bass. Crisp treble. A natural, not overly pronounced midrange. It was truly amazing how well all the parts and pieces came together to produce an all together effortless sound. (Well, there was about a 1000 watts of BAT amplification upstream to help out.) Still, a fabulous bit of engineering.
On the other hand, 12k is a lot of money for anything. There used to be a larger selection of Thiels, so you could pick your price range and get really exceptional sound which made the upgrade path not so steep. Looking at price for performance for the new models, I'm going with the 2.4 at less than half the cost. That's only my opinion and not a slight on a fabulous 3.7.
