Rwwear - hum started at time of new XOVER. BUT this was also same time that I "buried" the IC's under the floor and got new IC's. Thus multiple simultaneous changes. IC's above floor are great.
Ozzy - No TV or SAT in system - LP, DAC and CD player are only sources
BALANCED cables has fixed all issues even allowing me to use the dimmers in the room without a peep. Even slight hum in Vinyl subsystem (2 chassis phono preamp) is gone.
I don't know enough electronics to understand what "I fixed" (or more likely unbroke) but the end results are outstanding for about $120.00 worth of cable and connectors. All I can say is in my application/room/system -> Balanced IC's are great.
Thanks to all. Have a memorable Memorial weekend
