You have assembled some very impressive and expensive equipment. What strikes me as odd is your set up violates almost everything that would contribute to good sound. All hard surfaces not even a rug. ML speakers need to be placed well off side and rear walls for them to work properly. Even placing your equipment between the speakers is not ideal. Leather furniture doesn't help. I'd guess you losing 50% of your system's capability due to these issues. Maybe you're locked in to your arrangement by the room's configuration but you should at least `add `a carpet and consider some additional acoustic treatment.
