Otto, Do you have a dedicated circuit for your system? I recently installed two 20 amp dedicated circuits with high-end Hubbell outlets. Major improvement, particularly in the bass. (My system Linn Ikemi CD, Plinius 8150 SS integrated, B&W Matrix 803s). Not more bass, but cleaner and tighter (just what I wanted). I also added a new Quadraspire rack at the same time. Don't know how much improvement came from each upgrade, but the system it just what the doctor ordered! Happy listening. Joel
