Best way to spend $1000 on used bookshelf speakers?

Kef LS50
Sonus Fabers
Usher 520

I have all 3. All have WAF. Decent resell. All small footprints. And sound quality excellent. I prefer the Kef's for vocals, Fabers for Jazz, and the Ushers for rock.

There is a new pair of ELAC "Uni-Fi Reference UBR62's" on the Music Room website (TMRAudio.com). They normally list for $1200; and, they are one of the rare 3 way bookshelf speakers out there. Plus, the Uni-Fi series typically get very good reviews. Good luck in your search.

KEF LS50 Anniversary, very special ❤. 

Focal Aria and Kanta, Revel Performa, maybe some Monitor Audio Gold.
