Speaker Wire suggestions for feeding Rockport Atria II’s?

All: Looking for suggestions, or better yet, experience! Have a SS Constellation amp, fed with Madison Audio silver interconnects (Madison does not yet have matching speaker wire). Currently using Audience Au24 SX I have from a previous iteration of my system. Definitely sounds good, but I feel something’s missing, just can’t place exactly what. Bottom end detail and impact are my closest gut feeling. Maybe overall presentation a bit weak compared to when I’ve heard these speaks before. 

Anyway, I prefer a more lush presentation, would like to stay away from the “Bright” side of things. I know Rockport uses Transparent internally, but their better stuff is not in the budget right now. So, let me know what you think! Thanks in advance. 😁
