What to do with dedicated power lines..help please


Hi
Ive just had 2 dedicated 20 amp lines installed in my house..its been a great improvement..but just wondering should I separate the lines into amps ( and sub amps) on one and pre amp,cd,ld,dvd on the other...have seen some mention of benefit of separating digital and analog gear but Im not sure if this is what is meant or not...thanks

I also have read that you should seperate the digital components from the rest of the gear. Digital components are supposed to put artifacts into the line, I do not know as I have not tried. There are purists that say you should have everything on one circuit, you can do that with all your analogue sources and amplifiers, which is what I do.
I have heard the same thing about ground loop issues,that all should be on one line.Maybe one of the more experianced members can comment.
Like I said above, I have four seperate lines and my system divided among them. I have never had any grounding issues, but I can't tell you what the issues are in this regard.

Whatch out, are these separate lines from different sources or do they come from the same cable just splt apart.
Be sure to check them positive (current) with positive, with your volt meter so they dont add up to 240 volts!!!
The same positive should give you 0 volts, positiveo to ground 110 volts (of course) but if you get positive to positive 240 volts be careful because if you mix, say digital on one line and amps on the other you can be sending 240 volts through the ground!! (say you switch you plugs around)...

If they add up to 240 use only one line.
If they add to 0 use both; digital on one and the rest.

All the Best
Thanks everyone...they are two separate lines from different sources JS..They are about 15m from the service panel Bob..(if by sp you mean fuse box/circuit board). I havent had time to play around with swapping the sources yet but thanks for the input from all
