Cables make a difference. I’ve said that for over 50 years.
What is not guaranteed is that any particular cable in any particular system will effect a change or be an improvement to all. Regardless of all the marketing claims.
Advising someone to try what you own has an even chance of being bad advice. AND I NEVER do it.
This has been my experience. It is very possible that an extremely excellent speaker and amp combination will be best served by plain zip wire of adequate gage for the cable length. If a special cable is needed, it suggests that something unusual in terms of standard engineering practices is happening between the amp and the speaker. I talked to a guy who hooked some Wilson speakers up to a high end amp he had (can’t remember which) with some fairly expensive cables and the combination made a lot of noisy distortion - like really obvious noises coming from the speakers. He got a pair of very expensive cables that had a box with some secret circuit in the middle and it stopped the problem. Most consumer grade speaker / amp combinations would not have that kind of thing going on.
A lot of my experience with high-end audio gear has been that it is fussy stuff with unusual issues.
