I use a Furutech eTP66EG power strip. However, my wall socket is very much pedestrian. I have beeen looking to upgrade the plugs on my Vovox initio power cord (silver-plated solid core copper) that feeds the Furutech strip for some time now, trying all kinds of different plugs. Now, I've found my solution: FI-E11 (Cu) as Schuko and FI-11 (Cu) as IEC. It provides superior dynamics, more authority, weight and slam than e.g. the Furutech FI-E11 Gold oder the Viborg VE501 pure copper.
For some resaon, using the FI-E11 (CU) in the power strip, supplying power to individual components, doesn't work quite as well for me. There it tends to sound a bit tired, with somewhat subdued treble. It lacks refinement. But for the power strip, where the plug has to deliver a lot of wattage and current, it seems ideal to me.
