I don't own QS8's, so I can't comment on them. But I can tell you that M80's and the VP150 should sound very similar during a pink-noise test. M80's have more bass, obviously, but the mid and high range should sound darn near identical. They do on mine, anyway.
One thing you could try is to swap the VP150 and one of the M80's and do the pink noise test again. That would tell you if it's the speaker or the av equipment.
Is the VP150 brand new? It's possible that something might have come loose inside during shipping. It's happened before. Send an email or call Axiom.
