I have a pair M80v3s and can vouch for the sound quality. I have them without subs because I listen to music in pure audio mode which doesn't allow them anyway.

Then I have the LFR1100s and when I play them in pure audio it sounds as if the surrounds are playing. I seriously have to put my ear up to the QS8s to see that they aren't playing. If you want stereo speakers I would go with LFRs.
