I am running a Yamaha 673 and Polk TL1600 surround system. The TL1 center channel doesn't sound as crisp and clear as the surround TL1's even after using the YPAO auto setup. The volume may be correct for the distance, but it just sounds duller.
I double checked the polarity, I am using 18ga wire on a 6ft. run with Sewell Silverbacks on each end, and I haven't made any option settings that I can see that would account for this.
Any thoughts woud be appreciated.
