Rated 5 out of 5 stars
Amazing sounding speakers.
LS50 W were easy to hook up. Very sensitive to speaker placement. Once you get a feel for how the KEF app works you can fine tweak the sound to your preference. Overall these speakers excel in vocals, strong midrange, wide stereo stage and very revealing of instruments. Bass is adequate and strong depending on the song you are listening to. I purchased the KEF Kube 8B subwoofer to compliment the speakers and provided a more richer overall sound.

Awesome
Love the Grey with reddish speakers. I'm no expert, but you can hear so much more from the music with these. It's pricey, but everybody should have a good set of speakers if you can afford it. I had read a review that said "Just buy them. You won't regret it" and I have to agree. It was worth it.
