I am guessing that you are looking for very neutral, low noise floor and dynamic interconnects judging by your very nice looking system. Obviously we can’t know all the nuances of how your components work together or your tastes.
My first choice would be Transparent. Second, possibly Nordost… they would need to be used at about $2K. Nordost are really good in the upper levels and not so good in the lower level. If you still want more musical then the top levels of Cardas.
