Thanks Chris, very informative, now I see the error of my ways, I definitely need a second ep800 to balance out the boominess, I suppose I should have listened and bought two demure 500s but I craved the refrigerator sized 800 (oh wait I forgot about the invisibility cloak, looks like I'll have to wait for technology to improve).
Kind of a biased test though don't you think, based on a previous visit to Axiom Gene stated that he preferred the 500 to the 600 based on form factor/WAF (rather than listening tests), sort of no contest later when he performs "testing" without throwing the 800, much less the 600 that he previously dissed on the basis of form factor, into the mix.
Maybe this on the up and up, maybe audioholics is in the queue to pump the upcoming $999 dual sub 12 inch emo solution out of the gate, hate to say that because I'm tired of my own cynicism yet that would be my guess.
