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.
Suggest you try out an MIT Oracle AES cable. 
I am using and like these aes/EBU cables:

Snake River Audio Boomslang AES/EBU XLR digital cable.

@hgeifman +1 for the Snake River Boomslang digital cables!

This is an older thread, but IMO and for the sake of recognition, the Snake River Boomslang is one heck of a great digital cable! I started out with their SPDIF cable with BNC connectors (which I am now selling - shameless plug), 'cause I recently received a new AES/EBU Boomslang version from Jonny at Snake River on a trial basis.  It's not going back! After a couple hundred hours on it... wow! It has the speed and detail I look for, but also has an organic midrange, and a real, cohesive, spatial quality to it as well (this goes for both versions!). Though not coax,these Boomslang's sure have a LOT going for them, and musicality is top of list! No affiliation other than a very happy customer!

Read the Part-Time Audiophile and Audio Bacon review of the Boomslang to get a better feel for it. I whole heartedly agree with both reviews!

BTW, for what it's worth, in my system, I much prefer the Boomslang to both, the Shunyata Research Sigma AES/EBU cable and the HFC Reveal AES3, of which I owned both!
