The KEF LS50 Meta are great speakers in a smallish room with the KEF KC62 sub. I used them with the Benchmark AHB2 amp, CODA #8 amp, and KRELL Duo 175XD. They were all great combos.
I gave my LS50 Meta to my nephew and got the cheaper Magnepan LRS+ for $1000. The LS50 Meta is a bit better on the details but the LRS+ is a massive wall of sound and I think a better speaker.
Only issue with the LRS+ is that it is a lot harder to drive. So, you need a powerful amp. The AHB2 is not the best amp the LRS+.
