SPEAKER CABLES FOR ATC SCM 40?

Hi,

I'm using Van Del Hul Magnum speaker cable for my ATC SCM 40 now.

I had tried the Epic Twin speaker cable of Chord Company today but I was not satisfied with the sound.

It sounded too crispy at my current hi fi system.

Could you recommend any other good matching speaker cables for ATC SCM 40? 

My system is Audire legato pre amp, Classe CA301 power amp and Rega Apollo CDP.

Thank you.
