The KEF meta sound in general is very neutral and detailed. I’ve heard various and own the ls50s (~1.5K) + powered sub. Nice distinctive modern looks in general that will appeal to many these days, otherwise simply all business when it comes to measurable performance!
Compare with my Sonus Faber Concerto Domus (older model, listed in the $4k range or so in its day ~ 20 years ago) which sound completely different ie I would subjectively say warmer and more "musical", the music just flows nicely, a very special flavor of sound. Then there is the Italian craftmanship that went into its design......beautiful!
Compare with my Ohm 5000s, much bigger, not completely a fair competition as a result, but very wide dispersion pattern, pseudo-omnidirectional, tonality is somewhere in the middle of the other two but closer to the KEFs, still neutral maybe a touch of warmth, but unique design delivers the lifelike "you are there" type sound that I always just want to sit and listen to for hours on end. A new comparable pair from Ohm would cost ~$9k these days.
