I my experience the biggest difference between any interconnects is fhe difference between silver and copper. You're looking at one of each. Because the current is very low, a quality silver plate is almost the same as solid silver.
This is a heated subect, so I'll preface it that this is my opinion based on my experience. I'm not trying to say those that disagree with me are wrong.
I find that silver tends to boost the highs, which some intepret as degrading the lows. Turn it up so the lows are the same as they were with copper and you have boosted highs.
Some people are finewith the boosted highs. this can be because their system is a bit weak in this area for their taste. It can also be because they have hearing loss in the high end and this works great for them.
So if you are happy with the sound of your system with copper interconnects, stick with copper.
