I’ve had LRS+, .7, 1.7i and 3.7i at home for long weekends. In my room and setup, the .7’s were the most coherent and impressive. The 1.7i had more bass but just didn’t have the same midrange magic. The LRS+ and the same type of cohesiveness as the .7’s but lacked too much low end and just sounded small. The 3.7i’s felt like two separate speakers… the ribbon tweeter just never connected to the rest.
The LRS+ are very special, but you need a small to medium room and gobs of clean current. I used my Gryphon Diablo 300 and even that isn’t overkill
