I guess my point is that to me, the true audiophile requires the best his/her system can deliver. Trying to do that for multiple positions means you are going to sacrifice the best. That's okay if that's what you want.
I do not buy into the thought, 'I'm a true audiophile because four people can listen to 97% of what my system can do.' Doesn't work that way for me. I'll take 1x100%
I've heard MBLs plenty at shows, and the good old Bose 901s of yester-year. I always thought the MBLs were great, if you like that kind of spread out sound. I like a bit more definition, and for a head singing to sound like the size of a head.
