Welcome! I also started this journey with the X-LS in mid 2020 (almost a year ago now), but I have to be honest; they're still sitting in their shipping boxes. I started studying high-fi when I began building a dedicated theater / listening room, and I stumbled across these forums through Danny's videos as well. I'm in the process of building a pair of Servo Sub 4 kits to go along with the X-Static and X-Voce speakers I picked up recently second-hand. I'm also waiting on four of the A/V 1-RS speakers from Danny. It should be interesting getting everything built and calibrated. I may be among the first to do a full 7.2.4 Home Theater setup with all of Danny's stuff (all except the ceiling speakers, which are Bowers & Wilkins). I may even get a wild hair at some point and send one of the ceiling speakers to Danny to create an upgrade kit for those, too.
I'll post more pictures and my personal experiences over the next few months as things come together. One final piece of the puzzle is a custom amplifier from Klaus (Odyssey Kismet) that may not get here before the end of July at the earliest.
Side note, I was thinking I could use my X-LS speakers as my surrounds, but Danny politely said, "no". So I scrapped that idea. I'll build those for another room in the house instead.
