Power cord for low-watt tube amp?

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.

@schipo,
You know that a fixed delusion, that is one that the person believes is true and persistantly believes this against any evidence to the contrary leads to a diagnposis of Psychosis.

I never listed my system but really do have them. Do you really think that people whose systems that are not dramatically altered by PCs are systemless? I disagree even though I have custom made Silver PC, and Audience AU for sources and also SuburuGuru's custom PCs for my mono blocks. I bought these just hoping that my sound would be optimized in some way. I suffered from audiophilia nervosa but remain uncertain about PCs value to my systems.
OTOH I strongly believe that ICs and Speaker cable have strong influences on sonics.
