Using a passive direct box to kill ground loop noise?

This was recommended to me by a friend who's into hi-fi as well as pro audio.

I'm getting a ground loop, using unbalanced connections, using cheater plugs "fixes" it but I know that's no permanent solution. Would a passive direct box solve the issue? If so, which ones are good? I see ones by ART, ProCo, and others...is this a "get what you pay for" kind of thing, or is one pretty much like all the rest? Since all the audio's going through this one box, it better not impart anything of its own or take away anything :)
