I tried to read all of the posts here, but I don't think I have heard you say what the source of music will be. Is he going to play discs on a six disc CD changer? Are you going to dock an iPod? FM radio?

I guess you could use a couple RTI AD4 or AD8 amps with URC KP4000 touch panels. These would work easily, then put in some macros to give them 3 or 4 Comcast music channels. "You want old school, I'll give you old school!"
