I had a pair of the their SP-4 speaker cables and they were very nice sounding. The cost to value ration is very good. They have an old version vs the new version in which they they pretty much doubled the wire count. Depending on how well your system sounds, you very well may have to spend big bucks to find something substantially better. I would look for a used pair to see if you like them. If not, you could probably sell them for a minimal loss.
