I can't imagine lifting the ground on my tube amps, which use a 2500V power transformer and run at 2300V plate voltage...instant death from a ground fault. Instead, I made a parallel earthing conductor (PEC) from 9 gauge Cardas copper litz wire, which clips onto the ground sleeve of the RCA on each end of the interconnects to the amp. This reduces the ground potential difference between the amps and the preamp, and greatly reduces any ground loop hum. Look up PEC on the net, it's a commonly used technique in pro audio. It works for me.
Why are there no high end cheater plugs?
Yes, I know there are safety reasons for not using such ground lifting devices; but as many audio magazines have suggested, the benefits from lifting all grounds except the preamp are quite substantial. But the 79 cent cheater plug covers much of the improvement. I made some cheater plugs using silver wire but Eagle plugs. They are better than the grey guys. Why does no one make a quality plug? I understand that at one time Siltech did make such a plug.
Please no "educate" me of the safety reasons for not using cheater plugs. I think the success that our immediate ancestors had in surviving two plug ac, suggest that chassis shorts must be quite rare.
