I guess symmetry would be one. I think I get better results with deeper mic locations too. Would like to hear your take on this.
Symmetry is tough because many people do not have symmetric ears. But, yes, the closer the better when you are trying to match the left and right mic placement.
We tried cutting down some custom foam tips and inserting the mics really deep into the ear canal. Probably not the safest thing to do, but the mics were far enough in that it was hard to see that the mics were perpendicular to the ear canal. The measurements from the very deep insertion was not good at all. In fact it was terrible! That result was counterintuitive, but I suspect that the Realiser recording was never designed for such deep insertion of the mics.
As far as the mic placement in general, it's nothing you wouldn't already guess. In my opinion, It's best to have the mics flush with the beginning of the ear canal. Not sticking out, but not too far in either. Also, the mics have to be perpendicular to the ear canal. Any angling towards the front or back seems to affect the measurement. It's really kind of a judgement call.When I look at the mics inserted, I can just tell if it's in the right place.
Even with all that, sometimes one measurement just sounds better than another. There are so many factors to getting that last few percent of accuracy.
I don't know if Lorr would agree about how much any of this matters. But it's also in their best interest to tell people how easy it is to get a good measurement with the Realiser. You don't want potential customers thinking that it's too hard to get a good measurement or that they won't be able to do it.
I don't think it's hard to get a good measurement with the Realiser. Yes, you have to know what you're doing and have to read the manual. But I think most people could do a good measurement. But like anything having to do with high end audio, it does take some work and skill to be able to squeeze all the performance you can out of a given piece of gear.
For example, with speakers, you can buy some really good speakers and set them up in your room and they will probably sound pretty good. But, if you educated yourself on speaker placement and trained yourself how to hear if there are problems, etc. then you could usually make the speakers sound a lot better. You could use a similar analogy to buying a video projector or large screen monitor. Most high end owners assume they will spend money having a certified technician come in and tweak their gear. It doesn't mean the monitor or projector will look bad out of the box, but it can certainly look a lot better in the right hands.
