I don't like Chord cables, especially the Silver coated ones. I see Audio Emotion has second hand Linn Silver I/Cs (all copper), which they might lend you. For S/C, I like Cardas, Vertere, Telurium Q, Linn K20 (very cheap from ebay) and Atlas. Also, due to the feedback of Acalex, Iceman and Mac.....Siltech and MIT.
IMO. If a system already has a very clean treble (eg. Super Tweeters), Silver coated cables can push it over the edge. Given how close the system is to being wonderful, I suspect it could all fall into place with the right tweek / source.
