Thanks Unsound, for the Ebay lead.
Unfortunately, over 400 miles and 6 hours drive time one way to Stockbridge Ga. is too much for this old guy. I'll go up to 250 miles if I can find some that look promising, but that is about my limit. I have decided though, that unless I run into some Audio Physics close by to audition, I'll just be more patient and watch for 3.6s. It is not as if I am unhappy with my 3.5s, just looking for a bit more. I am within easy driving distance of Orlando and Jacksonville and could stretch myself to the Ft. Lauderdale, Miami area so it isn't as if I'm in the middle of North Dakota.
BTW to the Vandersteen fans who have responded, I like my 2CEs a lot and do feel they do a great deal of what the Thiels do. My preference in no way suggests that I think the Thiels "blow away" the Vandys. I have a suspicion that Jim Smith of "Get Better Sound" might suggest that I have an excessive focus on "audiophile sound effects" which detracts from my emotional connection with the music. Vandys are a top shelf speaker in my book, as are the Apogee Slant 6s which I still have. I have to move some speakers out of the house, but all of them are so nice I hate to see any of them go.
Thanks to everyone for the inputs, I do feel clearer about my options and for now I'll opt to watch and wait for 3.6s.
