A good pair of shielded RCA cables.
I only used the XLR on my older QSC amp which had only xlr connections.
Then you will ask which rcas’ are better, etc.
you may or may not hear a difference.....I heard a difference using silver rca cables, switched back to standard rca’s. the highs were more out front but I found a good shielded pair from Blue jeans.And to save myself, I ordered them in a nice Kelly green color to make the wife happy. She likes green.
Try out a couple pairs to see which ones give you what your looking for. I went through 3 pair to find the ones that gave silence through the tweeter.
We live 1.5 miles from a radio station tower, so there is talk and such. After the better shielded rca’s were installed, it is much better now.
Happy hunting.
There is an ocean of cables, from 8$ - to thousands.
as I’m a budget audiophile, I found my old audioquest cables in the basement years ago, and still use them. I like them, if you get a proper shielded pair.
Plus audioquest has their lifetime warranty, which I used about 3 -4 years ago on a nice XLR cable pair.
Pulled them to use, they must have been 20+ years old or more, sent them in, fixed like new and returned, no charge.
that is why I buy them.
you may like other cables.
Let your ears be the judge.
Enjoy, I always liked swapping cables, it’s easier them swapping components. :)
