Stevecham: CS6 could be interesting; i don't doubt you're happy. I rank the CS7.2 just a notch below the very best speakers I've heard (Vandersteen 7, TAD Ref 1, Vivid Giya, and Avalon Ascent) but better than Wilson W/P 7 and 8, Revel Studio and others. Of course, it's always tough to say for sure when the room and electronics are always different, not to mention the intervals between my auditioning.
IMO, Thiel made some of the very best drivers but he failed to tweak the crossovers and wiring as much as he could have. There is a pair of CS2.4 on ebay for a reasonable price but it is missing the speaker cable nuts. I half-tempted to buy that and trick it our with Cardas binding posts, upgrade the crossover (per posts earlier in this thread), and make it bi-wireable.
