Wow!! That would hurt.
Marble floors........sounds sweet.
A couple thoughts.....
You could order the M80's and ask Axiom to send you some resistors. If they are too "bright" for you tastes, the resistors will tame them down a little for you. I haven't installed them, but might just to see what the difference will be. The only reason I would, is that I have no treble control.
I hate to throw my opinion out there about sound comparison, but you're pretty much screwed on the auditioning idea. See if you can find a set of Paradigm Studio ref III's. The 100's sounded more like the M80's than the 703's did in my opinion.
I was wearing a T-shirt yesterday. It was raining and a balmy 38 deg. Today it's snowing and 29, so I reckon I better put a coat on, or stay indoors finishing my HT Room.
