I highly recommend using an Audio Grade gold plated phosphorus bronze or gold plated copper IEC inlet for an audio component with a power cord that's terminated with a silver plated Furutech FI-11(Ag) IEC connector. A stock nickel plated brass IEC inlet will only exacerbate an etched and whitened "washed out" sonic characteristic of the silver plated Furutech FI-11(Ag) IEC connector. Before ditching an FI-11(Ag) connector, upgrading a stock nickel plated brass IEC inlet with an Audio Grade gold plated phosphorus bronze or gold plated copper IEC inlet should first be explored.
IME, for insight into the sonic signature of the Furutech FI-11M(Cu) AC plug and Furutech FI-11(Ag) IEC connector combo, they can be compared between unplated brass AC connectors on the one hand, and gold plated brass, phosphorus bronze, and copper AC connectors on the other hand.
My impression of the Furutech FI-11M(Cu) AC plug is what an unplated brass AC plug "should" sound like, meaning replacing an unplated brass AC plug with a unplated (other than a corrosion resistant treatment) Furutech FI-11M(Cu) AC plug does not profoundly affect the presentation in terms of warmth, tonal bloom, and speed like gold plated AC connectors tend to do. Upgrading an uplated brass AC plug with an unplated Furutech FI-11M(Cu) AC plug may provide much better resolution and what sounds like a lowered noise floor with a blacker background, and notably less veiling with improved coherency, without taking an audio system in a far different tonal direction than before.
The silver plated Furutech FI-11(Ag) greatly adds to the sense of increased speed, detail, and even less tonal bloom. Depending on the system, application, and associated power cable, the silver plated Furutech FI-11(Ag) IEC connector can contribute to a sonic signature that's ruthlessly absent of tonal bloom and warmth, especially when it's plugged into a typical stock nickel plated brass IEC inlet. For increased tonal bloom, a variety of other IEC connectors such as a gold plated Furutech FI- 11(G) IEC connector can be implemented in order to "tune" the tonality of the presentation. However, an Audio Grade gold plated phosphorus bronze or gold plated copper IEC inlet should be at the top of the modification list.
YMMV
