There is one outlet that the Maestro should be compared to. The new Furutech GTX pure copper outlet.
My past experiences with using pure copper AC/IEC connectors for power cables have been a noticable jump in naturalness. You soon realise all gold/silver/rhodium plating has an artificial-ness about them.
Im not sure what the longevity is with using pure/red copper, but Furutech may have found a way to get high copper content and yet not have the problems with oxidation or softness.
