I just purchased new monitor audio 8i's for mains and 10i for center. I know they can be bi-wired by removing the jumper plate and then connecting 2 seperate speaker wires to the + and - sides. Do these speaker wires then get connected to the same post (+ and - for left and right)on the receiver? Does this really improve the sound quality? My receiver is Marantz SR8000 and I'm using 16 gauge flat Monster speaker wire. It was hard enough wrapping the bare wire around each post, that I can't imagine that there is enough room to put another wire on that post. Should I put spade connections on the ends of the bare wire?
