i have a yammy 1500 and pair B&W 603s3, pair B&w 600, pair B&W lcr60 and sub B&W asw600. The THX mode plays well, but the surround enhanced mode ( in dts es or d. digital ex) plays much better than the THX mode and the surround its more real and strong. I also tried several thx fims ( star wars ex.) but i prefere the enhanced surround mode than the so know THX mode. Iam missing something ?. can anyone give me some clue of an eventual configuration needed to boost the THX mode?
