Hi Naveen , I have a similar set up as yours... My power amps have two different inputs Balanced and RCA. There is also a built in toggle switch in the power amp so depending on the source i.e stereo or AV i choose the input via the toggle switch. Also the advantage in this case is i don't have to power on my pre when I'm using the floor-standers and the power along with the AVR for my movie watching experience. Earlier i used to have an Accuphase pre power set up and in that case too the pre used to switched off since the power had balanced and RCA inputs along with a toggle switch to select the input.
Cheers!
Anand
