Just thinking out loud.... If you added a 2 bearing Quill and there was play in the splines and or drive bearings, you could still have wobble / run out?
In my opinion if you have a good two bearing quill with all good parts it will exhibit very low runout. (Generally less than 0.001" in my experience.) Extreme error elsewhere may cause earlier failure of the quill bearings, but I think that is more hypothetical than real. And would likely present itself in some other way.
Woodshop Nerdery (youtube) reported on a new Mark 7 with what he felt was a bad from the factory quill:
So yes, it happens.
The current version quill that SS sells has a one piece spindle and larger bearings than the version Skip referred to in his video. I'm not suggesting it is necessarily or significantly better, these aren't the only changes. IIUC the current version has been around for 10+ years.

When did the Power Pro come out? It was 10+ years ago I believe. I bought mine in Dec 2011 and it arrive here in Jan 2012. At that time it had only been around for a couple of years. My guess is that SS upgraded (bearings?) the quill for the Power Pro since it runs twice as fast as the conventional head stock. Putting that upgraded quill (the only one they sell) in a conventional head stock has to be a plus compared to the older quills.
