Unfortunately, I haven't had much time to give the FIBAE ME proper listening attention. This morning I couldnt sleep and decided in the quiet hotel environment to give a listen. First, I love the design, thank you. The fit is super comfortable and the build is impeccable as usual. The first thing that strikes me with the ME is the same thing that struck me with the F3, the clarity. I was really expecting the bass to be the dominant tone, but to my ears it isn't, not even close really. All of the FIBAE line have clarity, with the F3 and ME actually having a similar signature, from memory, I will verify when I finally get off the road and home again. The bass is nice and it is more of a constant with the ME than the F3. I went through a phase where I truly liked only warm signatures and then shifted to liking more natural tone and clarity and now I find myself enjoying what the developers are doing, being able to extract the details and clarity and delivering strong, solid and detailed bass. Piotr, this is my favorite signature yet and the FIBAE line is getting stronger and stronger. The F2 is a truly fun and engaging listen, the F3 is confident in it's clarity and the bass is called upon when needed and the ME is somewhat of an F3 with more bass. Not bass for the sake of bass. It blends and creates a wonderful balance. The stage is wide and everything is laid out where it should be. I am not a Dave Matthews fan but his music has a lot going on and I have a FLAC version of Crash, which is the only one I have, and it has never sounded so alive and engaged. I only have a couple of cables with me, a Rhapsodio Silver Litz and the Ares II. The ME makes me wish for even a touch more bass, I could only imagine a hybrid with a DD bass.
To my ears this is your best yet.
