I currently have M22's front, vp100, QS8's, and hsu stf-2 sub. Curious which bookshelfs would be better for the two rear to complete my system. I also like to listen to stereo with all channels. I may be able to pick up a pair of used M3Ti's, how would these be? I only have about a foot and a half from my couch to the back wall and the speakers need to be on stands. Is this too close to the listening position or would it be ok? Thanks alot.
