FWIW regarding the post about powering the 803D, I listened to those speakers powered by the McIntosh MA6600 Integraded Amplifier, which is rated at 200 Watts, and it was no problem at all. The speakers sounded absolutely fantastic. I saw the meters reach as high as 140 or so watts on only a couple of occasions at what I considered very healthy listening levels. I'm sure your MC402 would be excellent with those speakers...
