What is it you are trying to accomplish by changing the speaker cables? In other words are you trying to get more resolving? More bass? More top end? I would bet the change from the DigiOne to the DigiOne Signature might make the most impact.
There is nothing “wrong”, at least until I can A/B the cables. I guess I want an overall better experience, because the actual cable can’t keep up with the systems performance. More of everything would be my answer
Depending on your level of DIY experience, you can make your own speaker cables for far less cost. A few minor tools, Some banana plugs, a little heat shrink tubing, and your good to go. A place like this one stocks component parts.
