Many thanks for posting this link. Mike! The Inner Fidelity discussion includes a couple of paragraphs that, let's say, were not crystal clear:
"Posturing differences in a DAP is fairly different from evaluating headphones, in this scenario many of the physical hurdles and pesky variables have been removed. Right off the bat it wasn’t hard to tell that the frequency response is pretty much even from unit to unit. What you get as you creep up the line is more meat on the bone, so-to-speak.
Less papery textures and more life. Heightened detail retrieval over any Apple phone is standard (for even the least expensive models) and the delta of this “meaty smoothness” appeared less from the SR15 to the SE100 than it did from the SE100 to the flagship Ultima SP1000 featured at the event."
I think he meant assessing rather than posturing in the first paragraph. In the second paragraph he talks about the delta of this "meaty smoothness." I think that misuses the word delta. Delta can mean the difference between two things. But he seems to suggest no so much a difference as an increase in a particular quality, i.e. meaty smoothness, whatever that is. Anyone understand what is meant here? Is there a bigger quality jump from the SE 100 to the SP1000 than from the SR15 to the SE 100?
