Hi all i have a question I currently have a Yamaha HTR-5840 with a Synergy Sub-10 and a C-1 center speaker given to me by my Uncle ,using Sony surrounds SS-MSP900 fronts and SS-SRP900 rears I took off my Sony STR-900 receiver..but I just never felt the sound is what is should be I am always tinkering with it to get the sound right..I want to use all klipsch speakers of course but since the Synergys are'nt around any more i was wondering what others will go with my Sub-10 and C-1 speakers I have or any other suggestions....
