Disclaimer: I am a Talon Audio dealer.
Given your list, obvious budget, and associated equipment, you should add the Talon Audio Raven-C and Khorus X to your list (we have the Khite-C and Raven-C available for audition, and will have the new Talon flagship speaker, the Firebird, available at the end of January). We are located in Boise, Idaho and in your vicinity. Please feel free to make an appointment for a listen.
Of the speakers on your list, the Sonus Faber and Wilson WP 7 are my personal favorites (never cared for the previous Wilson speakers, WAY too forward and clinical, but the new 7 is much more to my taste).
For what it is worth, I would put the new Raven-C up against ANY of the speakers you listed, regardless of price (Raven-C is $6950 retail). Ok...Start throwing the stones ;-)
Good luck in your search and a few points to ponder:
1) Trust your OWN ears. Buy what YOU like, not what someone tells you that you should like.
2) May sound corny, but the best equipment is the equipment you like the best!
3) Enjoy the search and don't let it turn into a chore (you would be surprised how many times this happens). If you start to feel overwhelmed after searching and listening after a period of time, back away for a bit and give your ears a rest.
