I've had surround sound since 1970 (starting with Dynaquad). All my systems have had identical electronics and speakers in the front and rear.
My current system has four biamped Divas, plus two single-amped Duetta Signatures to the sides. Power amps are Parasound Halo A21s. Program sources include SACD and Blu-ray Audio. Movies, too. (Need I tell you which monitor I'm fortunate enough to own?) A JVC XP-A1000BK synthesizes four channels of hall ambience mimicking major venues.
With first-rate surround program material (which is easy to find), it's You Are There. The Jacobs Mass in b is particularly realistic. I've always wanted absolute realism (or at least the illusion), and finally have the latter.
