Listen hard before you buy. I personally dislike the current KEF sound which is artificial and metallic, from the R series to the Blades.
JMHO and I am not alone as witnessed at the AXPONA audio show,
KEF Reference 1 or LS60
I using pre-meta KEF Reference 1s driven by an Ayre VX-5 Twenty amp with an Ayre QX-5 Twenty roon-ready DAC, Ayre DX-5 DSD disc player, and Ayre KX-5 Twenty preamp. The speakers are augmented by a pair of Velodyne HGS-15s with acoustic room correction below 80 Hz and high-passed at 80 Hz by a passive balanced Marchand filter. A plan I’ve been mulling over is replacing the Reference 1s and all the Ayre gear except the disc player with KEF LS60s. Any thoughts or suggestions?
