I am currently at the summit of my past years updates/purchases that made no sense at all! I purchased components at random with basically total ignorance. My current keepers are a Yamaha RX-1000 receiver, front Infinity towers (old) and Bose 161 Surrounds-(New)-(Wife and space considerations- don't ask!). The first step in an attempt to bring some logic to this mess is to purchase a first rate center channel speaker in the $300-400 range. The popular consensus appears to be Paradigm 7.0 unit. I will then move forward to replace my two front channel Infinity's next and so on. I will leave the Bose for last-(wish me luck!) I will most likely purchase a Yamaha receiver in the future, so the same receiver constraints will apply in regard to spaeker selection. Folks, help me out here! I need a logical plan to update and get the most bang for my buck. Many Thanks!
