Entry level Silent Source Signature speaker cables

Hello

I haven't got the Silent Source yet.
Yesterday, I compared my KS fascination to a Norsdost Heimdal.
I prefer the KS. High and Mid ranges are more detailed. The problem is the low end. Not enough details and dynamic.
I had the same feeling with the KS Emotion.
KS is very musical, transparent and detailed, but it lacks of dynamic, and I don't like the low end.
