It's the same technology Gecko have used for 20 years, and the same technology which Leadshine originally copied for their Dx drives.

But the key detail is, the D whatever drives, don't monitor the motor. They simply alter how they're drive the motor using various levels of micro-step morphing to avoid resonance, and allow smoother motor control, but that seems to be the point you're trying to avoid recognising by arguing over what is or isn't obsolete.
Yes, the DQ are copies, never ever stated otherwise. Never the less, they are very well made and for people who don't want to spend a small fortune on drivers it is still very good and I will continue recommending them. I can't compare with the Gecko, I think some things are actually better in the DQ, but that's just from looking at the specs. Again, just because soemthing is old technology, or analogue, it does not mean it is bad technology and that it has not been improved over the years.
