OK, a few things:
1. Now that we know this is a pair of actives, any sort of Duo-Lyre is totally out of the question. Even the lightest 68-shore version is going to be far too stiff, and that includes that InVision On-Camera mount which is the same exact stiffness in a non-modular format.
2. It seems DPA actives are close in mass to a Line Audio CM3. Line Audio doesn't specify it, but I just put one of mine on my coffee scale and it is 30.5g.
3. Given all of my Lyre trial-and-error with my CM3s, I can say with total confidence that what you want here is
a pair of individual 72-shore Lyres with your DPA actives in an SRS stereo mount. That is exactly what I use all the time, and the 72-shore lyres isolate the whole thing perfectly. I also own two pairs of 62-shore Lyres, but trust me when I tell you that they are
very compliant - far too much so for a stereo setup of 5 ounces 141 g. Your rig is going to flopping all around on you like some sort of audio Muppet. I use a pair of the 62 lyres each when mounting my CM3s
individually, but never as a pair in a stereo bar / clip.
