dorkwad, yes definitely, but usually I think double price. I always try to upgrade rarely but in as big steps as I can afford or think can afford. When new component including cable, burnt-in of course, is really much better you hear it immediately. There are more complicated situations when certain things are better and others are not or even worse, I had this fun comparing a few Purist Audio cables. And you know what - I sold them all and got the one that was better than them all in every respect !
Yeah, upgrading one set of cables might make sense but proceed with caution - you may throw the system off the balance and get worse sound. This is not straightforward matter.
