I recently undertook a similar excersize and heard many of the above. I went with SF Cremonas (in this case, cosmetic issues trumped performance at the margin). I liked the Sophias a lot, but - on performance alone - I thought the Vandersteen Quatro was the best of the lot. I'd also check out the Acoustic Zen Adagio which, while not delivering deep bass quite in the same league as the Quatro or Sophia, represents compelling value at $4,300. IMHO.
Good luck w/your hunt.
