I am using two GPXs and am very satisfied with the results. The first runs from an R-1 outlet to an Acoustic Revive distribution block and the second continues to my integrated. What little line noise I had is gone and both ends of the spectrum really opened up. Taste tests showed that installing the first GPX, before the distribution block, made the most dramatic difference in the system. The GPX's drawback, as Ckorody mentioned, is that you need a lot of real estate to maneuver the cord behind equipment, so I'm considering trying Oyaide's PA-23ZX for my CDP. As much as I like those bright red plugs, maybe this cable is more in line with the real world power requirements of a CDP (or ten CDPs!). Has anyone tried one?
Anyone have any experience with the Tunami GPX-R ?
Apparently the GPX-R will be terminated with Oyaide 004 plugs. The price will be $475. Are there any other differences ?
