My AC power has tons of junk yours may not. The 8 gauge ground wire is attached to multiple 12 foot copper rods driven ito the ground outside the listening room and then the preamp ground terminal. There is a seperate 12 gauge ground wire for each of the PS Audio units and the two monblocks soldered to the 8 gauge right at the preamp ground. These 12 gauge grounds are used as the ground instead of the ground from the AC circuit. There are two sets of dedicated lines each pulled as a three wire 240VAC with no splices from the main service box. One 240VAC is split for the Melos Monoblocks. The otheris split for the PS audio units. I believe that alporter goes further in isolating the digital from the analog AC circuits but I can't see any junk from the digital side on the analog line with my oscilloscope. I also can't hear a difference when I turn off the digital units. This is probably due to using Bybe filters before the PS audio units. I can when I turn off my DMX digital music satillite receiver but isolating that is a whole different post.
