Yep this time I can definitely rec the Ortofons. Enjoying them on all of the criteria that you're listing. Build on the VSonics are fine, not much to worry about. Some of the most solid and rigid (in a good sense) plastic on an IEM to date. Would cross the Atrios off, not the most stand-out mids, not even the least bit forward as well (build is fine). Probably should not take the TF10 as a benchmark for build against everything, they are exceptionally bad in this case, and well-known for it.
Would also look at the BA200 in this case as they fit most of what you're looking for quite nicely.
After lots of perusal and reading the feedback of people like Techno Kid who seem to like the same kind of sound signature, I let TwinQY tip the balance and ordered the e-q5. I look forward to my new IEMs and spending more time on the forum here and appreciate the help I got.
