PASS LABS XP20 or MODWRIGHT LS 36.5 DM

Hi there everyone. I am new to Agon and a new audiophile as well.

I am using modwright LS 36.5 Dual Mono Preamp w separate power supply with pass labs xa 100 monoblocks driving my dynaudio temptation w transparent ultra / cardas GR cables.

I am considering the pass labs xp20 preamp due to its accuracy , detail , speed and resolution based on reviews. I also like the warm tube texture of my MW. I havent tried the xp20 coz pass labs products are by order to my country.

This may not be an upgrade based on price but im expecting a good synergy for the pass xp20 to my xa 100.

Is it worth it ? Has anyone have tried these two preamp w d pass xa 100 ?

Thank you very much in advance to your thoughts and comments for this.
