A fantastic system

I upgraded to KEF LS50 wireless 2 and am delighted by the improvement in the music I am listening to. The sound demonstrates clarity and fidelity as well as more than adequate power. The speakers are very stylish and fit in our living room very well. I’m repeatedly hearing things in my music I haven’t noticed before. All in all a superb purchase.
