I am currently building my Denon/Axiom HT setup right now, but up until a week ago I was getting a lot of advice from my co-worker who recently built a Denon/M&K HT system. I have been to the local "High End" HT specialty store to audition the M&Ks. While the M&Ks were indeed incredibly detailed in the treble and mid range, they really lacked in the low ranges, and the addition of their subs didn't help that much either (was watching a fight scene in "Saving Private Ryan"). I purchased a pair of M3s after another friend recommended Axioms (never heard about them prior). I was immediately impressed by the crisp details and full mids, and even more so by the overal warmth of the Axioms. Just for reference, I will be using a Denon 3805 Receiver with M22s (front), V150 (center), QS 8s (3 for a 6.1 setup), and a HSU STF-3 for sub in a 19'L x 14'W x 9'H dedicated home theater room.
