Would look at Shunyata Venom’s in your price range. TheCableCo.com has a 30 day trial policy to see how they work in your system. Shunyata has been my go-to for years because they make high-quality cables with different levels of noise filtering. I expect that you will hear a step-up with these.
For the record, I did not believe that PC s could make a difference until a buddy lent me some and I saw for myself.
