Several experts have recommended having your digital components on a separate line from your analog ones. I am currently doing this on faith but have not done exhaustive tests to see if I could tell the differences. I intend to do so at a future date but other things have a higher priority. You can look at their arguments or try it yourself if you have separate lines handy as I do.
