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

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

Tuesday morning, I am having an electrician run two dedicated lines in my finished basement/listening/HT room. Currently (pun intended!), my equipment (pre, power amp, AV receiver, CDP, DVD player, tuner, DirecTV receiver, VCR) are plugged into a "normal" circuit, ie, one that just has a couple outlets running around two adjacent walls in the basement. The other basement circuit on the opposite adjacent wall feed my Velodyne sub and Sony HD RPTV. Nothing else is on these circuits. My amp is a McCormack DNA-225, so not hungry enough to *need* its own circuit.

Here are my thoughts after the new circuits are in: Plug the McCormack into one of the new circuits with a non-shielded power cord (VH Audio Flavor 4 perhaps); plug the rest of the analog gear into the other new circuit with non-shielded PCs (Flavor 2s perhaps); plug the CDP (Music Hall CD25.2) into the old circuit with a shielded PC (Flavor 1.) Does anyone have any different or further suggestions/comments. I imagine down the road, I may introduce some AC line conditioning on a trial basis. My guess is I may want to filter any digital noise from the CDP getting back to the breaker box.

Other info: I only have capacity (and reasonable budget) to pull two new circuits. Fortunately the breaker panel is only 8~10 feet from where the circuits are being terminated. Walls are sheet rock. I'm planning on using Porter Ports for the new circuits and replace the existing outlet(s) with them also.

TIA for any words of wisdom. I have read many here and look forward to more.
