Please,Help me choose new TA speaker cables

I'm using Transparent ultra and i'd like to upgrade them.

The local shop have TA UltraXL ,TA Reference and Super MM2.

They were offered in same price league.Which one should be the best choice in your opinion?

I had tried some cables from other brand before (nordost tyr,au24e,MIT Cvt) but none offer me what transparent have. So that i think i'll stick with trans.
