Hello from Lincoln City, neighbor.
For many years, I owned JBL S312's and still own S38's (which are just okay for surround duty). I currently run Philharmonic 2's in our HT...WITH a JBL center which was optimized by Dennis Murphy (Philharmonic Audio). The Phil 2's replaced a pair of $6,000 Aerial Acoustic 7B's (with pleasure).
As soon as funds allow, the JBL is outta here for a Phil center. I've auditioned most of the speakers on your list. While they're all acceptable, I would run, not walk, to the keyboard and order a set of Philharmonitors from Dennis. Those measurements you see on his website are the real deal (unlike some of the others on your list) and accuracy of Murphy designed speakers is a benchmark. Off axis performance is as good as you're going to get in this price range...except perhaps the Salk offering proposed by Fuzz...also designed by Dennis.
In terms of your 30 year old ears and the loudness factor...how large is your room? Most of your possible selections would be capable of setting my ears to ringing in an average sized room.
Of course the caveat to all this is that everyone's ears may prefer different presentations (and mine are significantly older and more rock and roll tortured than yours).
Much good luck in your search. Anticipation is the fun part!
Adieu.
