MBL 121 to full range speaker

Would like to receive recommendations on possible upgrade to full range speakers. I am living in an apartment so speaker selection would have to fit this constraint. The MBL 116 is an obvious selection keeping to the MBL sound which I certainly enjoy but I would like to especially hear from others who have found other speaker makes that I should consider.

BTW, I have Rowland electronics (synergy 2i/501/PC1) with MBL 1511/1521 DAC&Transport.
