All cables will sound different, not necessarily better. If the cables don't have any impact then this isn't your weakest link. What the buyer has to decide is if the difference in sound worth the price. I have owned Porsches in the past and you wouldn't see a 911 owner buying $35 tires on a $100k car. Sure the $35 will get you from point a to point b, but there is quite a bit of difference between a $35 tire and $600 tire. You don't see people claiming: it is just rubber!
