    "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

    I'd like to suggest that dedicated lines are unnecessary unless you're running very high-powered equipment. Of course your step-down transformer needs to be of sufficient volts VA capacity to power all your equipment.

    However, I also suggest that you isolate your EMI/RIF sensitive components from each other as I suggested above

    If your gear is on a circuit with fluorescent lighting, you will surely notice it. Why would you want other stuff on your Audio circuit?

    Dedicate circuits are always a good thing but are can be an expensive option.

    Regardless, it is always desirable to put EMI/RFI traps not only between analog and digital but also between each digital component

    Depending upon the location, true. I had a devil of a time finding an electrician who could successfully add two lines to my music room which is really an upstairs bedroom. The first one said it could not be done: the fire breaks in the wall prevented him from drilling down from the attic and he could not figure out another access point. A second one approached the problem differently, but required cutting some sections out of the wall to complete the job-which required some drywall repair and painting. Cost? $800 for adding two dedicated 20 amp lines to the breaker box. I found it worth the effort sonically.

    Having said that, the HT receiver is not current starved as were the tube amps. I use a basic Monster HTS-1000 on the sources and use a modest Belden 19364 based cord with the NAD T763.

    Luckily, I was able to do all the work myself and it cost less than $100 for the wire, breaker, outlets, and box. I did have fun fishing it across the garage attic, down a wall into the crawl space, and then back up through the floor of my livingroom, but I was able to do it all.
