I have a pair of 1989 LaScala's that I would like to use in a home theater / living room stereo set up and am wondering which center channel speaker would be most compatible with them. I ahave a set of Tnagent 30's that I've been using on the rear channels. I'm currently powering them with a DBX CX3 preamp and DBX BX3 power amp. But I'm considering using a Sony STR-DG-820 ot STR-DG-920 receiver. I;m not sure whether I'll use the pre-out and my old DBX power amp or use only the Sony to power the whole setup and maybe use my DBX amp to power a sub later. I'd be thankful for any suggestions from someone who's made a similar setup on which center channel speaker would work best as well as any other setup suggestions.
