Long (35-foot) Transparent Ultra interconnects worked very well for me in my system for many years. While the Transparent cables are generally very pricey in the typical 1-meter lengths, the upcharge for longer lengths is very reasonable on a per-foot basis, resulting in long runs that are comparatively very reasonably priced. If you buy used, you will probably be able to find a pair of Transparent Reference interconnects within your $2,000 price cap.
