I agree, Rhodium can sound good but does take a really long time for break-in and the consistent good sound. In my opinion, that's why when you read the forum here on Audiogon about the Furutech GTX-D Rhodium (R) Duplex Receptacle, members report very long time periods of inconsistent sound and 250 - 300 hours or more of break-in time.
Rhodium...hmmm
I recently purchased pc for cd player with rhodium ends on both...I wasnt feeling the mojo from it and was not content with lowend resolution/grunt.I switched ac/male end with nice furutech copper and it has made the difference...Im surprised at the difference that it has made.Bass has more info/definition/warmth and high end still has sparkle with the neutral transparency that rhodium (iec) seems to offer.I know this has been talked about alot and probably deserves a duh!.. Rhodium indeed has its place in my system after all this time.Like it.
