I'm running Qs-8's and a vp 150 with Nht super ones as mains and have no complaints. When I got my M3s I a/b compared them with the super ones and was surprised at how similar they sounded. The q's are just spectacular. It would take a helluva sales pitch (probably from a very female salesperson) to convince me to replace them, even were I to go to an obsene main like a focal or wilson.
