DTS:X is not even available. Some rumors says that it will come in January 2016, but I guess it will come March 2016 for lower models. I'm pretty sure on January you could find S910/X1200 at a much lower price. On my country, X1200 it's already discounted by $50. It was available 1 month ago and already got a sale.
Also upgraded from X1000 (same as X1100/X1200) to the X3100 and the bass is more tighter that I couldn't believe to my ears. Also on high volume, the speakers have high excursion and still manages to have very tight bass, it's unbelievable.
X1000 was boomy on trance/dance music, genres that have fast and lower notes. I guess you wonder how an expensive receiver will make your speakers. X4100W made my speakers to sound like studio monitors, a lot of details on highs, I could hear before. I heard details even on bass frequencies, on X1000, was more like a blend of frequencies. Now I hear easily every dB increase/decrease on a song. Same with X3100W on bass, not the same on highs but I was very disappointed by X4100 on movies so that's why I got X3100 in return.
