"Loom" cabling vs. 'mix n match' ?

I want to use a new set of cables for my awesome Moon 780D DAC v2 - - including a power cord, an AES/EBU input from the Moon 260D Transport,  and  RCA IC's (into a Shindo Giscours preamp).  I've read good things about Acrolink-Mexcel, Shunyata, Nordost and Purist among others.  But is there an advantage to using the same manufacturer for all cable types in and out of the Moon ?  Or might the cumulative effect be too much of a good thing which would be better improved by intermingling brands ?
Thanks,
Dr. John
