Having received much advice and assistance from several forum members, I have assembled enough gear to record some shows this week.
one with used Schoeps Colette capsules > actives > platinum nbox to go into my old R-05 recorder, with used PFAs that could go into my Tascam DR-100mkiii as an alternative
Ended up with MK4s, which sound the best to me overall in my listening tests, but also MK41s for more difficult or noisy situations, and MK4Vs which fit best in the concealed location for subtle field recording purposes. Obviously don't need both 4s and 4Vs, but couldn't decide based on the samples I heard so wanted to test for myself and decide which one to sell later. Baby nbox will be on the way soon but I won't have it in time for the shows this week, my first live music since the pre-pandemic era. Don't know if I remember how to go to shows, but it'll all come back to me soon I hope.
and
one with DPA 4060s > DPA MMA-A/d:vice preamp > refurbished iPhone SE running metarecorder and the DPA app.
Still a few lingering questions about setting up the DPA rig. I wasn't planning on using the windscreens for

but when I tried putting them on just to test them I fiddled around for a while and thought I was going to rip them and gave up. If I ever need the windscreens hopefully I'll figure out how to put them on without damaging anything.
Also in the midst of setting up the iPhone and am wondering whether to delete mail and message apps from there. I will keep it in airplane mode of course but wondering what else I can do to keep that phone clear of any distractions and interruptions while it's recording.
Also wondering about the metarecorder file format - CAF is better, I assume? But my computer is too old to run dropbox so I am wary of huge files. I like the R-05's automatic seamless file-splitting feature. That would come in handy for making phone files easier to transfer to computer.
And still trying to figure out a few details about how mic placement would differ with the different capsules.
Thanks again to everyone who advised me. Wish me luck...
