I want to build up to having a music first home theater in an 18' by 20' room with a vaulted ceiling. My plan is to use the AVI DM 10 active speakers that I already have, as front speakers until I can get proper floorstanding ones in the future; then I could move the DM 10s back as rear speakers. I figure I should start by choosing a center, and I think I want to get a floorstanding one, maybe even the same as I'll eventually get as the front left and right. If I could find some miracle JBL M2 for $5000 I'd splurge for one, otherwise I want to spend less than $4000 per speaker. The other two things I'm considering is the upcoming Vizio OLED and the upcoming Marantz SR 8015. I'd appreciate any and all advice. Thanks
