Those are very interesting choices. The AC cable has a very high current rating and the DC is old school design, now illegal in the UK for AC but fine for signal and speakers. Also a very good price, the same price as my recently acquired 5T00UP speaker wire (Gamma Infinity without the fairy dust).
The irony is that they are tinned copper, the same type of wire used in fuses by Bussman etc. that some people don't want to use as being inferior.
