Microdot is fully and properly coaxial through the connection, so it might be better shielded than many 3.5mm connections..
But it may be that microdot is more of a lab standard coaxial connection for measurement gear and its use by DPA descended from their B&K origins. In non-audio high frequency applications it probably achieves better impedance specs where that becomes more critical.
After making accommodations for them, I don't mind them if I don't have to disconnect them regularly. They seem better as a compact in-line connection than panel mount, where they seem a bit vulnerable to me.
With my upcoming re-rigging, I'm shifting from mini-jack to mini-xlr wherever possible, partly because they are locking, and partly to handle more than two signals through the same connection wherever necessary, for better management of the cabling for 4 to 6 channels by reducing the number of separate cables and connections.
The gory details of the re-rig for anyone interested- For the 4 x 4060 rig using standard dot-terminated mics, I'll be making a new short-breakout adapter (4 female microdot > 6-pin mini XLR). Probably using two of the cables I've linked above instead of old male dots cut from other mics plus barrel adapters to separate stereo 3.5 plugs as I'm now doing. For the 6 channel rig I'll be building a 6 channel snake, with longer female-dot terminated cables to the four 4098 (4098 is microdot terminated right at the end of the gooseneck a few inches from the microphone), and shorter cables spliced to the longer integral wires of a 4061 pair which are currently terminated to a stereo 3.5mm plug. All those will either terminate to a single 7-pin mini xlr, or in pairs to 3 separate 3-pin mini-xlrs. I'll re-terminate the 6 PFAs as three 3-pin mini-xlr pairs, and if using the single 7-pin at the end of the snake, I'll also make a 7-pin to 3 x 3-pin adapter. I'll also need to make a short fullsized XLR to TRS patch cable pair to adapt the 2 of the PFAs to the TRS inputs of ch5&6 on the DR-680.
I'll post some photos once I do all this, probably in a couple months.
