I couldn't agree more with

I've had the FX17 burn-in for about 60 hours and, like a fine wine, it's only matured and Improved more and more.
If you're not a believer in burn-in, this IEM might just change your mind. Of course, there's a cerebral burn-in where you need a period of time to adapt to the new sound signature, but it's not about that. I can simply notice that something doesn't quite fit: the cohesion, some strange peaks, the bass seemed stiff without the corresponding extension. These are easily perceptible things, and I can easily discern when my brain doesn't quite recognize a new type of sound, that something just doesn't quite come together.
Well, having said that, I can only describe the FX17 as an ode to balance, good taste, and exquisite refinement, only available in IEMs at least twice its price and more. We are talking about a level of soundstage, resolution, layers and not least, the timbre, all top notch. I perceive FX17 as a pleasant signature in W, I would say that highs, mids and lows share exactly the same prominence in the spectrum, nothing stands out above the rest, however everything is there in perfect harmony, another thing that I love is how it resolves complex and crowded passages with an ease and realism that I have rarely appreciated in other IEMs, it reminds me in many ways of Macbeth, we are talking about something serious.
My biggest concern is the bass extension which is becoming more and more satisfactory, although it is not a basshead set it can certainly move a lot of air if required, with a very high quality texture and precision, the mid-bass is a bit reserved but the sub-bass extension is very good, it goes deep very well, although there are IEMs that go deeper, I insist, FX17 is an exercise in balance and impeccable good taste, however the bass will satisfy the vast majority of people, in addition, I am sure that a change of cables and sources can extract a little more juice from the bass.
The big handicap is that even though I still want a little more bass, not much more certainly, right now I can't even think about giving up everything that the FX17 offers as a whole, also, I'm not sure I could find everything that the FX17 offers with more emphasis on bass without spending thousands of dollars, as I said once before, if FX17 had been released under any other brand that the community considers premium and had a price twice as expensive, many people would be applauding and praising this IEM that is without a doubt, among the best in the sector.
With all this I may seem like a fiio fanboy but the reality is quite different, until now I haven't finished connecting with their products that if I remember correctly have been BTR7, Q15 and FH9, but I will add that fiio's good work with FX17 makes me really want to try their next flagship M27 and I think FX17 deserves much more repercussion than it's getting.
I don't usually make many recommendations to manufacturers, but in this case I'm going to allow myself to recommend to
@FiiO that he does everything possible to carry out the European tour and also, it would be crucial that the unit that is sent has between 50 and 60H of burn-in.
If people want it, I will update my impressions a bit when I try the AMP15 and also the fusion 1 and Aristotle cables that are on their way to me and should arrive soon
