what is the best power cable for the dCS Puccini

I experimented with the power cables on my system. I found a strange thing-when I reverse the DCS Puccini power cord L with N, my system started to sound in completely different level (in a good way). It's easy to do with European Shuko plug. This is the opposite connection than specified by the manufacturer. It seems that Pucinni U-Clock also works better with inverted power connection. I want to know about your experiences.

With my DCS Scarlatti stack I use Siltech Ruby Hill. For me the g6 and g7 Siltech cables work very well indeed, giving resolution without edge.

Clearly a matter of taste, but I've been using Anaconda VX with great success and a Taipan on my U-clock (only because I had it) and didn't wish to spend an add'l $2k for a current Anaconda class PC. Sounds outstanding!

Not to be disagreeable-but-the best pc will be the one that best removes noise from the current--in both directions. I am presently looking for information on that. Also what type of isolation device is best to remove line noise and digital noise emanating from the device operating.
