"As Hy-Fi mentioned, I also have a dedicated line for each."

I run the AMP,preamp, cd player, subwoofer from single line output into a stepdown transformer. The output of a stepdown transformer is 110v connected to a surge protector into which all my equipment is plugged in.

I running my equipment in india. Here Mains voltage is 220 v. I need to run thru a step down transformer before I can plug my equipment in. Do you see any problem here.

Thanks
