Fortunately I haven't (yet) had to use a lifted-ground to eliminate my (rare) hum problems, so I can't speak from self-experience. Electrically this is a no-no, & is even considred dangerous, esp. if there's a bypass cap. failure, etc, internal to the "problem" component. But realistically you can normally get away with doing this. I have read that componenets can be "tuned" to sound best when ideally polarized as-such, but have never tried it. One possible approach is to experiment with Mike VansEvers' (www.vansevers.com) two-prong reversible power cords. They have detachable grounding leads, which are then (theoretically = read disclaimer) connected, once the 'best sounding' polarity is found for that component. But then again, some 'philes realize a better sound with no ground at all. I question the practice of using a cheap cheater adaptor on a high-Q power cord; you're possibly degrading it via that approach? But if that works for you, you could (theoretically) remove the ground prong from the original plug with a hacksaw. Or you could (theoretically) even remove the ground connection inside your outlet box (although that would un-ground everything pluged in there). Another possibility is to buy some Wattgate, etc. plugs and use them in place of original plugs, sans ground prong. Then there's the dedicated-ground approach to try too, but that's not a cheater plug, & falls way outside the ream of Justlisten's question. Sorry - I've gone on...
