DF is the wrong curve in this case - there is a diffuse characteristic from the room. What should be applied instead is independent-of-direction (ID) curve or similar ear canal simulation. (boost 3k and 6k, less than DF, do not cut highest end) Alternatively, for IEMs, wear a deep insert IEM shallow but still sealing.It helps a bit, but the actual issue has something to do with phase/group delay, head shadowing and not magnitude - that's why crossfeed helps so much, especially if my crossfed positioning estimates are mostly correct.
This one is better

I'll do some more sophisticated recordings (especially from a greater distance, since all of these were extremely close) to see how much of an image I can get after I have added canals. I can't really figure out how to mic an acoustic from a distance (especially fingerpicking), so it'll probably be vocals or sax.
It depends what microphone type you use, the room, and what the end result will be.If you are using your omni's, get someone whose hearing you trust to walk around the room and find a spot where it sounds great. Place omni mic there. Done.

Place omni mic there. Done. If I am using the tiny pencil-style omnis, how will I control for self-noise being amplified with a quieter source like a guitar from a distance? I have some 10mms which would have less self noise... I'll try and post a distance strum recording (not that the strings are good for strumming...) tonight to test the image.
Silicone nozzles must be longer than you'd expect - the ear canal volume has to match and that's 0.7-1.3 cm^3. (Not 2cc, that's way too large.)Also watch out for edge effects, do flare these in a horn pattern, and watch out for the seal with the capsule.I used 4mm diameter tubing and attached rubber "horn" with good results for one EMM-6. Without the horn, you'll get notable 6kHz half-wave resonance or null.
