How is the airflow in the cabinet? Are you heating your house with that amp!! Looks good. I always preferred the detail of a smaller speaker... and the soundstage and imaging... it must be hard with all of the gear between the speakers to have a really 3d soundstage... I would move the cabinet over and get longer cable runs and put the tv on a small stand on the floor .. or scrap the entertainment center and go for a floor set up... low profile so that there isnt much interference between the speakers.
Nice rig!
