When I demoed the KEF LS50 (before meta), I also demoed the KEF R700 floorstander which sounded similar but with bass extension. So maybe a used KEF R700 here .
I demoed multiple Zu but it never resonated with me- from the many forum comments, seems few resonates with its sonics so is highly subjective. Zu is typically highly efficient so caters more to those with lower amp power.
