I just want to say that Oritek X-2's were mostly designed with cd. So, if you don't need silver, I would suggest you investigate these for your cd player. Ori says that just having them in your system provides many of the benefits of these interconnects. I can guarantee that Ori has auditioned his interconnects in many systems. Can you say that about all the interconnects that were formula based? I bought about 2 feet of them, which are very cost effective.
