I just got my new HK 7200 a couple weeks ago and now I wanna do 7.1. My speakers as of now are VR950 mains VR920 center and CR75 rears. Place I bought speakers allows upgradeing as long as new speakers cost 50% more and i wanna stick with boston cause i like there sound. So my question is should i use direct or dipole for rears and surrounds. I use stereo 50% music 50% movies. I have not heard dipole speakers much so i don't know which way to go.
