I don't mind frequency response focus as long as the presentation of the note is well represented, i.e. good dynamic range, good decay, good texturing/articulation of details, even intensity, etc. We can always EQ things to suit our preference in response, but we have little control over how notes are fleshed out by the earphone. This is simply a byproduct of the driver design, and we have minimal influence over this.
I've used a number of the Hifi-man products including the early RE0, the RE-Zero, the RE252, and RE262. I did not like the RE0 for its short decay and low dynamic range. Apparently it was changed later on in some way, but I've never used a newer version. I really liked the RE-Zero which had good dynamics, good note texture, and was pretty even in presentation. For $99 it's an awesome product that's really natural and really well balanced. The RE252 offers really high clarity and an incredibly well balanced presentation. Texturing is great, but it just falls a little shy in dynamic range. The RE262 really hits the dynamic range out of the park which was great to see coming from the RE252, but it lost texture and decay making low frequency notes very thin despite retaining actual sensitivity. High frequencies lacked raw energy like the RE252 but again had the sensitivity. the RE262 is likable and awesome in terms of dynamics, but the thin note and low high frequency intensity really made it colored and midcentric versus the much better balanced RE252. I really wished and still wish the RE272 is an evolution of the RE252->RE262->X where one could retain the new dynamic prowess RE262 but gain the balance of the RE2525 and improve upon texture/decay of the note. Hearing that it is treble strong doesn't bother me really. Frankly, treble can be very hard to do right. However, I would like to know how balanced the presentation is and how much low frequency presence and thickness is retained. I can always EQ, so treble focus isn't a problem. However, I can not magically add note thickness and texture if the driver simply doesn't function that way.
So, how is the note presented with the RE272? How does it vary through the frequency range?
