I came across this thread and thought I would post something a little different than what other people are doing. I decided to isolate my digital from my analog.
I have 3 30 amp 220 volt circuits feeding my stereo with 10 gage wire in my new dedicated room. The circuits are feeding 3 power isolators two 3 kilowatt isolators and one 5 kilowatt isolator. The isolators are transformer based units. The 5 kilowatt isolator has two 110 volt feeds, one for analog and one for digital. The 3 kilowatt isolators each feed 1 mono block amp. I am using hospital grade copper plugs to feed all my gear.
This seems to work well for my system. The isolators are located under my house on a concrete slab off so I dont hear the hum. I like using 220 volt better so you dont have to run a neutral line to the isolator. Seems like to me the neutral line is where a lot of the noise comes from.
