I've decided to rip all CDs directly to FLAC (nearly there), then play around with placement. Also playing around with surround sound (PLII) settings, which is interesting. Pretty sure I prefer stereo mode ("pure" on my Onkyo AVR). Still getting the upper midrange peak, but it could be me. I'm ordering a Radio Shack SPL meter to help make this more objective.
I have not spoken to Axiom about upgrades...yet....Maybe going to the v4 versions will help, but I'd like to spend the dough right now (young kids tend to be expensive....). But someday, that omnidirectional option looks mighty tempting.
Thanks for the ideas!
