With bad acoustics and no room treatment planned you're wasting your money on buying good gear. If what you want to hear is music while in the kitchen why not consider ceiling speakers?
I'm not trying to be snarky, just realistic based on the information you provided.
My POV is based on my home systems which are-
1. Main system in a dedicated room with acoustic treatment.
2. Living room system with no treatment.
3. Bedroom system with no treatment.
4. Ceiling speakers system with no treatment.
Most audiophiles spend way too much money on gear, and little or none on treatment.
