In retrospect, I’d venture that the GE digital cable nicely balances the GE s/c. However, I believe improvements can be had, as the s/c is just superb – capable of easily revealing upstream changes (cables or otherwise). They share the same toe-tapping attribute as the digital cable (not surprisingly) but improve upon openness and seemingly eschew compression (through the s/c to my surprise). The end result of Cerious Technologies' latest seems to be exceptional fidelity to the live event, though my experience thus far is limited to Bob’s GE digital cable and the amazing speaker cable.
I happen to also value Dennis’ Chimera Labs cables and coincidentally find they do timing as well. In my case, I recently discovered Jorma digital to be a superb combination with the GE s/c, where the Jorma is just as linear as CL but deemphasizes speed just a bit (much like the GE digital). That said I wouldn't discourage anyone from trying Bob's digital cable. Bottom line, the Cerious Tech GE digital cable is more musical than many S/PDIF cables I've tried and a bargain to boot.
