Huh? You "drove from the very tip of the mitt in Michigan to Nashville."? I admire the zeal and dedication but wouldn't Music Direct in Chicago have been less of a haul?. They probably wouldn't have everything you're interested in, unless they have some trade-in stuff, but they are a large operation, very highly regarded and have lots of high-end stuff. Judging from their website, looks like they have Dali.
You listened to Opticon 8mks right "out of the boxes"? In other words, not broken in at all?
You also seemed to have done your auditioning in different sounds rooms with different acoustics, different source gear and sometimes with speakers not exactly optimally placed in the room. Not exactly a good way to go about critical listening or auditioning gear. While it's virtually impossible to control all conditions for critical listening, the more you can replicate or come as close as possible to your home conditions, the better sense you'll have of how something might perform under your roof. Room dimensions, seating position or the proverbial sweet spot, how your room is laid out, furniture, windows, rug, no rug, hardwood floor, ceiling height, space behind the sweet spot, etc. are factors to take under consideration. While you'll never really know how speakers will perform until you get them home, have them hooked up to your gear and fully broken in, trying to control as many conditions as possible in auditions or critical listening sessions will help. Listening to things in a haphazard way is risky business, generally speaking. It's also a good idea to find out what the return policy is in case you end up being disappointed and want to return what you buy.
Best of luck!
