Here is my 2cents worth,depending where you live depends on the improvements of dedicated lines.Yes there will still be benefits of line conditioners,however in my experience high dollar power cords seem to make less improvements with dedicated lines.I have had this done several times(moved several times)and one thing that I never see mentioned is if budget is a concern if you switch your lines at the box where the outlet where the stereo is plugged in is the first line to get juice that by itself is a upgrade in itself.I did this once and got a remarkable improvement and then later had seperate line and ground put in when finances allowed and couldnt tell a difference so I felt like a dip.But keep in mind the condition of your electric plays a big part in the effect.My friend lives 20min away and has the worst electric I have ever encountered but I live in a small city out in the country with little electric trouble while he lives in the big city and has to run conditioners on just about everything.
