I use this for my DSS mains conditioner with a Furutech cable and FI-e50 ( non-NCF) schuko on the other end. The powercon did not deteriorate the sound, it is clear, detailed but not very smooth in a high-end way. I guess this is due to the silver. But the Furutech rhodium will take care of the signal becoming smooth enough. Considering the price this powercon is a real steal.
