This is hard to say.
Some folks who say all cables sound the same will say buy the cheaper ones. Other folks who can hear differences will say each brand and model of cable is different and no way can it be said one general cable notion is better than another.
So I say if you cannot hear a difference, then FOR YOU there is no difference. And don;t waste your money.
If you can hear a difference, you would not be asking?
(my two cents)
For normal audiophile use, there is not a whole lot to be said for RCA over XLR or XLR over RCA.
Each is implemented differently in various ways, so a generalization is just not easy.
And if the expensive RCA are so cheap.. they may be fakes..
Do they have the serial numbers, or provenance to prove they are not fake?
