help with bedroom set up

I have a cayin KT 88 with some nice Atacama speakers stand in silver, i would like to find a pair of monitors to match this tube amp!

I do love reference sound, I own the acoustic Zen Crescendos with the Ayon Triton on my main system, I am sure you guys can help me to decide from your own experiences.

I was thinking on Nola Boxer, cause I would like to stay on budget new or used market!

Any inputs highly appreciated!

I will wait for your advice to make any further move.

Thank you in advance.

Regards
