Not having worked with all of the various components at one time, the only thing that i would add is that you really should check into "specialty" power cords. I know that the GCD-750 responds very well to this type of "tweak". Quite honestly, i was not overtly impressed with it and then i swapped a cord and it REALLY changed the sound for the better. Much blacker background with increased soundstage and air. Quite honestly, i was pretty blown away by the difference that it made. Sean
