i'm newbie but very interesting to know the test you did. Is that mean Denon does a good job? Or M80? coz i'd looked for a NHT absolute Zero (6ohms) for my denon(8ohms), but finally i back to Axiom M3(8ohms). And now im still confusing about the risk of a sound system which seting up with compenents (receiver/speakers)come with diff ohms.
