Full size amp for JH 16pro

Hello everyone.

I own a pair of JH16pro and am looking for a best possible (or close to it) desk top (full size) headphone amp for them. in the future i want to get full size cans as well(probably K1000). for now i have an option to get SPL Phonitor, violectric V200 or something from Meier Audio. i don't want to give any hints. just what i am concidering. I am looking for opinions only from self experience.

I like studio sound but not flat and cold. just to give those JH16 more sound stage.

my source : Ayon CD1, portable DAT

thanks all of you for your time and experience.

i just want to love the music for a long time.
