While you're at it, you really should consider 3 dedicated audio circuits. With your high-powered amplifier on a dedicated 20 amp circuit your dynamic headroom should just blossom even at low volumes. Then you should have a dedicated 15 amp circuit for your digital source (because of the digital noise induced back into the line) and another for your preamp. Even a low-powered preamp sharing your amplifier's circuit draws just enough to strip away the dynamics. If your electrician can do one, he can do three. He'll just need to double up on a few of the circuits in the service panel. Oh, and if you choose to do this, you should have him connect all audio circuit grounds to the same common isolated ground if possible.

Joel, Thanks for your suggestion. It is an old house but I will check with my contractor to see the complexity to install the dedicated circuit. By the way, you have an excellent CD player. Happy Listening. Otto
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
