Hi Michaelzay, I enjoyed your review and find that I have the same impressions between Gold and Rhodium Furutech GTX-D wpo's, my cables are copper!, The Tara labs Zero Gold I/C, Tara labs Omega Gold speaker cables, Tara labs Cobalt power cord that is terminated with oyaide ends, the Rhodium is incredible with these cables, I went through a shock factor of the synergy with all of this, The Gold did not have the magical sound stage presatation or the Resolution that the Rodium brought out of my cables, you seem to be the first audiophile that knows what he is talking about, has nothing to do with tube or solid state equipment, like you said, rather it has everything to do with cables synergy!, well said Michaelzay, one thing that is most important that I have not said to no one yet, is the fact the Rhodium is incredible on the $5,450.00 Tara labs Cobalt power cord that is this,, Another industry first is TARA Labs' propriety annealing process, known as SA-OF8N 99.999999% copper (super-annealed, oxygen-free, eight nines pure copper). This creates a unique, long, unbroken crystal structure called mono-crystal which has exquisitely smooth and detailed transfer of frequencies over a very wide bandwidth. pure copper, which is the purest in the cable industry,even more pure than occ copper that is 6-nines,also versus cheaper power cords that I do not use that I had on hand for many comparisons that was not so much of a huge improvement like putting the Rhodium on a very good pure copper power cord, cheers.
