My current 5.1 setup consists of a HK AVR510(70*5) w/ Polk Audio-RT800i(mains)-CS4001(center)-RTi28(surr)-SVS 20-39PCi. I am thinking of upgrading but am having a hard time finding speakers I like better. Maybe M60-VP150-M3 or QS8 for surr. Also like Paradigm Mon7-CC-370-MinMon or ADP-370. Would the Axioms be a big upgrade from my Polks and how do they compare to the Paradigms I mentioned. Would the 6ohm impedence be a problem. I am also thinking of getting either a HK AVR7200-OUtlaw 950/7100-Adcom 860 PP/7607 7ch. Any help would be appreciated. By the way I'm about 80% DVD/20% Music
