I used to have the KEF LS50 Meta + KEF KC62 sub in my small office, 12x11x9 (+ 4 extra feet in closet). That was very good. My Benchmark AHB2 was more than enough to drive them. I used a lot of other amps, and they all were good.
A year ago, I picked up the Magnepan LRS+ to try. They cost $1000 but need a lot of power. I have tried amps from the used $1000 PeachTree GAN400 (good) to the $16k CODA #16 (great).
The LRS+ are 3 feet from the from wall and I am 8 feet away. The sound is huge, a wall of sound. There is depth to the sound because the panel radiates the sound in both directions.
I needed spend $300 to improve the sound with Magna Risers (feet). My minor complaint about the LRS+ is the details could be improved. There is a $300 cross over upgrade that is supposed to improve the minor issue I have with them. I am waiting on feedback from someone who got the cross over. I may get it if it is easy to install, otherwise, it is not a deal breaker. The LRS+ do too many good things.
I also feel it is easy to place the LRS+ in my room, the KEF LS50 Meta was also easy to place.
