If I was looking to spend $2,000 on balanced cables, I’d start with Iconoclast 4x4 cable in the material of your choice. I like that the designed by someone that not only demonstrates that he understands the science behind cables, but also recognizes that there’s more to cables than the measurements. His designs are very weld thought out, but they are also offered in multiple conductor materials. You also get 30 days to send them back for any reason.
I might be able to talk myself into the budget BAV variety at some point. Unfortunately, the rest of well above anything I’d consider to be a reasonable purchase.
At a minimum, read the iconoclast design brief. https://iconoclastcable.com/xlr/index.htm
