Fine, but then why debate with me and not giving him better advise?

My own experience is just as valid as anybody else's, but if I am wrong, fine, explain why and where so we all can learn something. Saying that I am wrong does not help anyone.

Even like for like on voltage Digital drives will make difference to both speed and smoothness.
It doesn't help if in theory it can spin faster when in reality the limits of the ball screw is reached. Of course, if you just spin the motor milling air (or just spinning) then it may be smoother and faster but will you REALLY see any difference in real use? Will the difference REALLY be as much as the difference in price? I doubt that.

This isn't about Digital is better just for the sake of it. The truth is, whether you care to accept it or not, is that Digital is better for several reasons and anyone who has had shity Analog drives will tell you this.
"Shitty driver" is the TB chips based drivers, not the DQ542MA. Anybody who claims the DQ542MA is a "shitty driver" has no idea about what he is talking about. Yes, no doubt that the digital drivers are better, the question is just how much better. Dismissing my experience is fine by me, but if you want to help the OP then answer his questions. I'll be fine with my "shitty drivers" as long as they do what they are expected to do, run as smooth and fast as they do and are as reliable as they are.
