I bought 2xM-60's, 1xVP-150, 2xQS-8's, & an EP-350 a few months ago. Wouldn't ever go back to what I had. Never even considered returning them either. I'm thinking about getting the same setup for my father, but the room they would be placed in isn't suitable for the quadpolar QS8's. So with the above mentioned setup, I'm looking for advice on whether to get M3's or M22's to serve as the surrounds. I appreciate any feedback.
