I lived with the X2 for some time and, while I loved them*, I would unreservedly recommend you go for the Alexx. To me, they sounded faster, more open, and more dynamic than my X2s—more modern if you will. They do seem more difficult to set up and much more difficult to drive, but your amplification should be more than enough to make them rock.
