Rega Isis cd player ......Dedicated 20 amp circuit?


I just bought a Rega Isis cd player and noticed it has a 20 amp power cord. Do i need a dedicated 20 amp circuit for this player?

dill I was looking at the Rega Reference power cable web page and specifications say....Power lead cable rating 20 amp.. Thats why i thought i needed a dedicated 20 amp circuit. But akg_ca answered my question 
As far as I know, from the installation cost perspective, there's no difference between running a dedicated 20 amp line and a 15 amp line from the breaker box. It just gives you the option to use the wall plug in the future for a high current amp.
guys what is the sonic dif. between the SS and the valve version if I am going to use as atransport-
