Good replacement power supply for Pure i20

Hi all. I just bought a Pure I20 to play the musics from my Ipod through my strereo system (DAC + amp). I was wondering if there is a better power cable for it because the original one looks soo cheap. Im sure a good replacement will also bring more audio quality.

I saw this pack option (power supply + huge power cable) but it is soo pricey :

Let me know if there is another option for that.
