I've recently upgraded to the Marantz sr7010 and here soon had plans to install 4 ceiling mounted speakers. After much research and some correspondence with Todd felt I might have a hole in the sound. So feeling as though I might as well go "all in" figured why not purchase 2 more rear speakers. On 4/18 I'll be completing my audio setup with 6 Klipsch rb-51 II speakers for a 7.2.4 setup. Here's to hoping for audio nirvana and impressions soon to follow.
