Czarivey,
You stated "Niether [sic] Rhodium or Gold-plated termination will have substantial differences in performance after all ..."
My experience is that there are substantial differences in my system between gold and rhodium. My system prefers rhodium.
Yes Sabai, your (tube) based system prefers rhodium. I agree with Rja's and Czarivey's opinion, in the case of the new GTX-D wpo's, there is NOT a drastic difference between these, despite the plating difference. The major mojo is in the base metal (pure copper), and the slight lean towards warmth vs resolution in the gold vs rhodium (respectively) is more related to a slight 'shade' vs night/day difference.
