I would have to disagree with you Psychicanimal. Most of us on this forum live in "electrically noisy" areas. Care to explain your conclusion a little more?
It's all in the Audiogon archives. An audio system is about--in order of importance:
1) power
2) room acoustics
3) vibration/resonance control
If those are PROPERLY taken care of, just about any decent component will sound great, from the little & classic NAD/Proton 25W receivers and up.
When you think about it, how "dedicated" is a line when it still shares the same incoming, common and ground from your box ?
A dedicated line offers no interruptions between breaker box and system outlet. Its purpose is dual fold: isolation from cross contamination and the *beef* factor.
As for grounding, that is very true, especially for those who still use tube electronics. My ONEAC 3KW isolation transformer/filter has a 'patented virtual ground' that isolates the building ground from the transformer's. You heard it! Also, DeZorel makes world class filters with an optional ground filtration module.
