Biggest problem would be from amp I think.Table power supply should be shielded,and motor of CD shouldn't cause a problem.But don't put anything on UPC200 if possible and when you canm sperate as best possible.See if you get EFI hum then move componets around to try to solve problem.ZOne of the reasons (at least in md fi set integrateds) that sperates sound beter is yes they use two seperate power supplies but also because the boards fro the pre and amp section aren't sandwhiched together the way they are in integrateds and recievers.Expensive integrateds sheild the elements to prevenmt EFI.
