If you can upgrade your cables now, you can do so without too much worry. It really didn't matter that I got the right amps, after I got the right cables, and before I got the right pre. That is my experience. I am sorry to hear that you can't find any used or is it new Cardas where ever it is, where you live. Did you try the Cable Co. in the USA? I am fairly confident that the better Cardas cables with "Golden" in the name of the cable are what you want. The biggest problem is price, these cables are expensive, even used. I don't know what Chord has that is similar.
