I agree with Rushton and Rodman99999.
If you check out my power filtration system set up in my system on Audiogon you will see that I filter all AC power with two 5 KVA isolation transformers before the AC gets to my dedicated lines. That power feeds three different high end audio systems in the house.
I started with dedicated lines and liked what I heard with in the music. Added the Isolation transformers and the sound improved more so.
So, if you own your home I'd start with dedicated lines and good AC outlets, and then add to it as money is available.
