Although I agree that analytical IEM's should possess those requirements you mention those can almost only be measured by measuring instruments. Can't see Joker's reviews of IEM's mentioning those requirements for him to call something analytical. From Head fi's "Describing Sound - A Glossary" something analytical is "Highly detailed". If treble is too withdrawn/barely noticable I can't see it as analytical (imo). But I understand what you are saying.
This is my understanding also. I base my descriptions on what I hear, using the commonly used glossary of terms. If I stray too far from that, I end up leading readers into a maze of subjective semantics.
Still, it is interesting to hear others opinions that put more emphasis on technical measurements.
Insightful comparisons Deni5. Some more vs Re-272 when you're ready :-D
