Hi Rgs92 - the .5 series cables are a hybrid cable made of 1/2 Signature 10 and 1/2 Resolution Reference. They should be a pretty good match with Sonus speakers. You will find S/R cables have a bigger soundstage and will be more dynamic (lively) sounding than Cardas in most systems, although the thing about generalities is that there are LOTS of exceptions. I hope this helps.
