The LRS+ is great in a small room, I use one in my office. Though the lowest model from these guys may have more resolution. They also have models that go up to $50k.

However, for me if want a large sound stage and imagining I would look at a KEF Blade Meta (or 2 Meta).
My Livingroom speakers, the Yamaha NS5000, also have great imaging but the Blade is the best at that for me. The Yamaha drivers sound better to me though.
