In a nutshell, the X² is the CDX and TTX combined in a neat and good-looking package with a few key differences: the CD section has no built-in effects, the vinyl section has no key lock or 78RPM (Who uses that anyway, right? But you can still do it with 45RPM +73% pitch.) And there's no digital output or MIDI at all. It's basically a no-nonsense, professional-quality CD, MP3, and vinyl player in one unit.
