I’ve heard Soundlabs with massive Boulder amps as well as Ayon Triton amps, Kingsound (least favorite), and Martin Logan Neolith with an all McIntosh components and a dual firing balanced subwoofer in different rooms at different times. The Soundlabs were impressive but the Martin Logans were the best over a number of listening sessions. They have a large sweet spot and great micro detail and also had the widest dynamic range with the subs integrated well into the system. It was a tough decision to go with ESL or Magnetic Planer Speakers, I made the decision based on my sound preferences and the true ribbon tweeter in the Magnepan 20.1. Both types of planer speakers are amazing in my opinion and just like all speakers have their specific challenges with set up and room placement/interaction. That being said, I had my 20.1s in an 800sq/ft studio and they sounded great. Not as good as my current space which is much bigger but really good nonetheless. Planers act as line sources and I think they get a bad rap for needing a ton of space or power to operate corrrectly. If you get an amp that will double down in power from 8/4 ohms and can find one that gives stats to 2 ohms you have plenty of power to hear what they can do unless you listen at ear splitting volumes.
Try them out and have some fun!
