I think Scott (bmwr75) makes a great point. There are other factors that I would start with before focusing
on just the speaker cables. But...if you need speaker cable due to system changes, rearrangements, longer runs, etc I would start with good quality, well engineered cable. Nothing too exotic until you address other (and often free) limiting factors. If you feel you've addressed all the other issues and you feel the speaker cables are your last hurdle then look for the higher end cables. My system right now is in a less than desirable setup. My diy speaker cable is good enough....for now. I've had more improvements with interconnect cables (again, diy) over speaker cables. But a well engineered, good quality cable is the place to start. Check with Ryan. I think he runs River Current cables. Maybe he can help you out. You'll see the River Current logo at the bottom of the werb page.
