Dedicated Lines, Now what?


Hi folks. Just had dedicated ac lines put in for listening. Had 2 circuits installed. I use a digital front end, Nuforce V2SE's and a JRDG Capri preamp.
What can I combine together on the same circuit? I would assume that I want the digital by itself, but can I have the amps and the pre on the same circuit?
Also, I notice that there is a slight "hiss" coming from the tweeters. You can only hear it if there is no music playing and you get your ear right up to the tweeter. It dosent seem to get louder if I turn the pre volume up. Anyone know what that hiss is and if there is anything that can be / should be done about it?

Hevac1-
It is all outputs. And my center channel as well (and it dosent go thru my 2ch pre at all)
Do you have cable, if you do try disconnecting it to see if the noise go's away.
Also I had a hiss in my system after cleaning up my power cords. I put them too close to each other. I redid them and space them further apart and my hiss went away.
With this two circuit setup, if (say) an integrated or pre/power in one duplex, how best to deal with the power for the digital and analog (TT) sources?
