I imagine that the main function of many cords is to reject EMI and RFI as well as provide clean unimpeded power that a power cord for a smaller amp is still important. That is of course if you are a cable "believer" or not? In your case, intuitively speaking, the gauge of the wire, probably does not need to be very large relative to a 20 Amp cord intended for a 500+ watt class A amp.
Then againg I doubt that you are going to find yourself seriously considering a garden hose or Anaconda for your small amp. It seems that a very high quality silver wire perfectly constructed as in a Japanese type masterpiece is probably what your shooting for.
You might try Audiio Asylum cable asylum and search for PCs for small amp. That might give a sense of whether there is any buzz about it or not.
