"I just sold my excellent floorstanders because I am tired of having broken balls and a broken back lugging them around, and trying to locate the ideal "sweet spot" in my 12 X15 room."
You realize you don't have to put them back in the closet upstairs after each use?
"So what should members do like Tom, who want to get away from this bright, fatiguing, unreal, edgy sound??"
For British speakers look at these: ProAc Response (the older models are fine.), Spendor S series, Living Voice, Mission, Rega, Monitor Audio, Audio Note
None of those have that hard to listen to quality you mention above. If you're willing to buy used, you should be able to find something at a reasonable price from any of those brands.
