I've found rhodium, like nickel, too hard to grip well in either AC or speaker connectors. I avoid them at all costs, preferring copper in the former and silver bananas in the latter.
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.
