My bias is that ICs from source to integrated will influence the "sound" more than any other cable. I own KCI (koolcables)Firefly balanced silver ICs and they very have nice treble. Very reasonable cost for the quality and service. I also have the Silkworms balanced which, to me, have as optimal a combination of accuracy/balance, transparency and top-to-bottom extension but are more expensive.
Just my 2 cents.
