Ascend Acoustics makes some really nice gear. Their more expensive bookshelf speakers would be in your budget on the used market.
Bookshelf speaker for an apartment
I rented a 1BR apartment as a 2nd home and want to upgrade my speakers. I currently am using Totem Mini's through a Denon AVR-X6200. My speakers in my main system in my home are Sopra 2's. Due to Covid I am unable to audition speakers but have read good things about the Focal Chora 806, Aria 906 ane the B&W 707. I would like to keep the budget under $1000 for the pair but go a bit higher for the right speaker. I welcome suggestions. Thank you.
