Best Balanced Cable for Electrocompaniet

I was hoping that someone with experience of the Electrocompaniet EC 4.7 and AW250 DMB could make a recommendation for balanced interconnects between these two units as well as speaker cable between the amp and a pair of Talon Audio Peregrines. I'm currently using Straightwire Black Silc but looking to make a change. Perhaps the same Manufacturers cable throughout the entire system. My transport is a Camelot Merlin feeding the Perpetual Technologies P1A and P3A. Your help is greatly appreciated!
Thanks
