The question should realy stay open whether you will benefit or not.
Firstly, the phono cable is expencive and has some parameters you realy don't need to count for CD-player. The thin gauge of phono cable is to minimize reactance that realy matters on such small signal levels while on CD-player having 2V output it realy doesn't matter.
It's like using a bazooka to kill a fly instead of simple newspaper or fly-slapper.
