" I can only relate that for me the LSA is a clear step up from Parasound Halo A21 it's replacing, and while my W4S SX-1000R monos are awesome, I find the LSA to be smoother and more refined, while being quite competitive with the W4S on the bottom end."
This is interesting as I found the exact opposite to be true. I have the Parasound A23+ in a professionally calibrated system. The Voyager, while refined, just didn't engage! It's sound did not project into the room like the Parasound did. My wife and I were not engaged in comparison. The Voyager checks most of the boxes if you break down the soumd, but the sum of those parts just didn't add up in the end. The Parasound was much more engaging and just sounded more correct. Parasound tonality was much better too. I put on a Sinatra sound from a well recorded album. It's very dynamic and sounds fantastic on the Parasound. With the Voyager, it sounded like I was streaming it. His voice had only a fraction of the weight that it should have had. It sounded flat and boring in comparison. Bass is also tighter on the Parasound. When the horn section came in, it was much more dynamic on the Parasound than the Voyager. This was my experience over several weeks with it. I wanted to like it, but the Parasound was too good to let go.
