For your speakers, Clarity Cables Organic are a great solution. They have no area of weakness, and will make all other cable sound thin in comparison. I have very transparent, detailed speakers with authoritative bass in VMPS RM40 BCSE ribbon speakers with all the upgrades except the OXO. I found out about the Clarity Cables Organic from Doug Schroeder, one of the reviewers from Dagogo Online. He has been using them for years. Heard them at his house. They would be within your budget at the selling price. I got my 8 ft. pair for about $1500 including 1 ft. long CC Organic jumpers. After break in, they have been virtually a perfect fit. They are also open and have very good texture in the lower mids and below.
