Don't think in terms of money--think in terms of noise control strategy. For less than $75 you can get decent used isolation transformers in eBay. I bought a 400W/ 4 amp Power Var for $55 and plugged my DAC to it. Al I did was to open it up and use Pro Gold on all the contact points. What a difference in my system! I am already using a Tice A/V Solo, so my CDP is hooked to the Digital outlet of the Tice. Now I don't have to keep my power amp plugged the Tice! Even analog performance has benefited. I also have all these things plugged to a Panamax Coax Four and in its power cord I installed a Highwire Wirewrap. Simply amazing performance...
My next step is to buy a 3000 W isolation transformer (220V in/ 110V out) and install a line filter at the 220V level, prior to entering the transformer. I am thinking of using a De Zorel module and a Tice TPT power cord. I talked about this with George Tice and he was very helpful. Once the electricity comes out at 110V, I will use the DIY parallel filters in (www.magnan.com).
I am doing it this way because I am a nomad and rent. You could try something like a DeZorel and filter just before your dedicated line. You'll still need to do some digital noise reduction management.
Jon Risch has a section on DIY balanced power in his website, too.
Hope this helps out.
