I strongly encourage you to check out Hapa Audio with their Ember RCA cables fitted with KLE Absolute connectors. To say their new design is phenomenal would be a complete understatement. Even in a modest system like mine, the addition of these cables has improved the sound past what I ever thought possible, to the point I even postponed some bigger gear updates because I didn’t feel the need to upgrade. With a lot of other rca cables I have tried, I bounced between smooth but dark/veiled sound or detailed but thin/tinny/clinical sound. None have been so smooth and palpable sound while still maintaining that vivid, airy soundstage. And hearing the inner detail buried down in the music come to life for the first time is incredible. It is like the old adage that an item is perfect not when there is nothing left to add, but when there is nothing left needed to take away. They are by far the best cables I have ever owned. I realize they are under your listed budget, but I know their performance does not match their price. One big perk to buying from a small company.
