I had the X1 for about 4 years before recently upgrading to XT1. That is by far the longest I've lived with a couple of speakers. Started with MA GS10, then MA PL-100 and then Focal Diablo before buying the X1. I was quite surprised that I liked the X1 more than the Diablos regarding the price tag but they just felt more natural and less analytical than the Diablos. The Diablos had of course better lows than the X1 but that was it. The only minus with the X1 are obviously the lows (you can't beat physics) but for a cabinet so small they still do a heck of a job. I'm using a Velodyne DD10+ that IMO matches them perfectly. The Raidhos have a HUGE soundstage, a glorious mid and treble and never given me listening fatigue (that ribbon tweeters usually do). And you have the opportunity to upgrade to the XT1 but honestly as good as the XT1 is, the X1 really is a brilliant monitor. The XT1 gives you a tad more detail (though I didn't think it was possible) and sounds a bit more organic. Also the lows are a bit better, but nothing that matters using a sub.
Happy listening with the X1, I'm sure you will be very satisfied!
