AES cable for Berkeley Alpha Dac

Hello.I'm using my alpha dac 1 with the alpha dac USB and would like to know if it would be optimal to use the same cable brand all the way to my preamp. Spectral 15ss/200s combo.Right now i'm using a mix of Cardas USB, Cardas neutral ref. to preamp and a Straightwire AES cable.I have no immediate plans to change anythin I'm just trying to optimise my digital components.
Shunyata's AES Python Zitron digital cable is the best I've ever heard. Lengthy break in is required, though.
