OP, of those you mention on your list, I've listened to the Persona's, GE's, and Olympica's at dealer setups. For me the Olympica's were the winners from that group, but I like a more neutral to musical sound than you appear to from your brief mention of your preferences, so not sure my preferences will be super useful to you. The SF's also look very good to extent that matters.
You're taking the correct approach by listening to as many speakers as you can. I listened to over 20 speakers over 6 months before choosing Spendor D7 nine months ago.
Good luck
