Are two dedicated lines better than one?

Sorry if this has been discussed before,but next week my electrician is coming to put in a dedicated line.I need to connect my Lamm LL2 preamp,ARC Classic 60 amp,Meridian 588 CD Plyayer,SME Model 10 Turntable and ARC PH1SE. I was going to install one line with 4 outlets but I have 5 components.I do have a Chang conditioner that I can use but would it be better to have a second line put in while the electrician is here? Do 2 lines introduce more noise than a single line? Is it better to seperate components to different lines? I would really appreciate any advice!
