Speaker input, which one, Magico, Avalon, Yg, Rock

Tough decision, Have recently updated all my Spectral with all the latest Spectral, 400 Dma, 4000sl, 30ss11. I currently have Avalon Edilons, 2002 purchased. I like the sound but am looking for a better bass. I like music not over detailed or bright, I need to hear before I purchase, but will never hear all of the above in one place. I would appreciate input as they relate to Spectral . I am considering, Magico q30, Avalon compas, Yg KIpod 11passive, and Rockport Atria. All are excellent speakers, but which is the most musical and fits my 15 by 18 by 10 ft room. Thanks. , I also like the soundstage I now have
