Lifting grounds in the system.

MWP is dead on right, but so is Bob, as far as the GFIC breaker is concerned. Good old ceramic fuses are best AND you REALLY can hear the difference---if you clean them with Kontak or something similar. (Better dynamics, strange but true)

I lifted the ground on my system about 5 years back after a phone conversation with Audiogon member "Skull". Thanks again Mike, what a difference it made. Maybe he will see this post and refresh the star ground theme for us all, and for me once again. (Sorry, mine is behind the wall now, and I might forget to mention something important). I also agree with Bob bundus and Detlof, the GFCI recepticles have really messed up the sound in every system I've heard them in. And yes, try to install an older sytle sub panel in your listening room which uses the older style screw in fuses. (It does make a difference). I found a 100 Amp panel at a electrical surplus store, disassembled it, had it powdercoated and installed by my local electrician. (so they are out there, and it can be done). Just my 2 cents ...

If you really want to mess with a floating ground. Go to Radio Shack and get the two prong foreign travel outlet adaptor, no. 273-1406D for $1.99. This will allow you to go from 2-prong polarized (one prong is wider) to simply 2 prong (both the thin kind). Then you can flip your connection over to try the connection with the prongs reversed. I am sure the building inspectors out there would not approve of this either, but a lot of you like to live on the edge.
