How many dedicated lines?


I'm planning on running some dedicated 20 Amp power lines to my audio/home theater system. My question is how many separate lines should I run? I've heard of one audio system where every component practically had its own line. Is that overkill? Would two or three lines suffice for an entire system? In all, I have about 11 different components that need to be plugged in. Thanks for your help.

Yes that is correct & it's another good point! All the evens are on one of your 120V phases and all the odds are on the opposite phase. Best to use the same side for everything, hopefully most all the noisy loads in your house are wired on the opposite phase, or can be rewired that way (I did that). Don't unbalance your transformer's loading too much though.
Craig, I was referring to Bob's recommendation to have an isolated ground which is not to code.
Read again: "consider isolated grounding". I am not recommending it, but many users do so from experience so I just threw that in. However think about what is your objective? Are you more intersted in good sound or in meeting code? Poor analogy: When I'm in a hurry to get somewhere, the last thing I worry about is obeying "the rules" (speed laws)
