Hi Melbguy1, I do not understand why Chris said he uses both the gold and Rhodium in his system, I tried that, it was horrible!, they worked against each other, a real train wreck, weeks of testing revealed someone can only use one version or the other through out a system, atleast that is what happened to my system any way, also, Chris was dead wrong about what his recommendation's were for my system, The Rhodium over and over again was the clear winner on my solid state amp and tube/solid state Hybred digital cd-player that run's direct to amplification, extrodinary transparent hugely, I do not believe at this point untill I do more auditioning that one would have to use the same wall plug's through out, just the wpo's.
