Yes I can attest to the comparison between the LS50 and Wilson speakers. I had been running some LS50 for a few months moving them around from room to room as I was doing some remodeling. I thought wow these rooms really sound bad, hopeless for audio. I got a deal on some Wilson duettes and put them in the system that had the LS50 in on of the rooms and OMG what a massive difference. We need to re do the alphabet if LS50 and Wilson are both considered class A.
I am pretty happy overall with the sound of my Freya + and when you read that it's considered to be in the same ballpark of sound at the 16K Audio Research pre then I think why bother.
