what is the best super speaker and why?

Legacy Whispers - no one - no way beats the midrange of these speakers or the balance of the entire presentation they give you in any room.

Not to poke at a hornet's nest, but I couldn't ever answer that question without knowing the room size and accoustic environment and the type of music being listened to. You can ask preferences under certain conditions but to ask for the best (absolute) requires criteria since there is no best under all conditions. Even at $100K a speaker designer makes tradeoffs which might or might not be to your liking.
Maybe I'm just a grump because I have not listened to any of the speakers mentioned.

kirk930: IMO, none on your list are as sonically satisfying as the avalon eidolons, which are under $21k (standard finishes-msrp). the most overpriced speakers in your group are the jm labs utopias. i have it on very good authority that the utopias were priced at the $30k level to attract a demographically-identified group of audio snobs who felt it necessary to raise the highend speaker entry bar to that level; according to my authorities, jm labs would still make a substantial profit were the utopias sold for $15k. FWIW, i have listened to all the speakers on your list. -cfb

I read somewhere that the burl finish on the avalon eidolons sounds the best :)

I would put my actively bi-amped, Krell driven, B&W800's up against any of these speakers. A few years back, Krell used them to introduce their FPB line. Dan D'Agostino chose them over the Wilson X-1's (which he also owned). He had called the bi-amped 800's "the best speaker on the planet."
At the original price of only $15K, it was a steal. On the used marked, it shouldn't be passed up if one can afford the amplification and crossover.
