Well, I had a brief listen, so take anything I say as a mere guide and indeed with a pinch of saltStorm has become a bit of a meme in some quarters due to delays with production, inconsistent reports from London, present radio silence, as well a curious and blunderous lack of appearance at CanJam SoCal. That said does it really have a noteworthy bass response? That's what I was responding to mostly...I thought it was fundamentally a reference monitor.
To give an idea of my impressions, I was very impressed by both the Fir Xe6 and Kr5 which I listened to alongside the Storm.
I listened to Kr5 after Xe6, and what struck me about the Kr5 was that it had a *comparatively* much more neutral-sounding tuning to me, but with a really outstanding low end, great rumble and slam. I really enjoyed it.
With the Storm, which I listened to after the Kr5, my immediate impression was that I felt it to have a huge, holographic soundstage, sounded very airy and open, exquisitely detailed and yes, quite reference. But not at all sterile or boring, and the bass struck me as certainly being fairly elevated, with more slam/impact than rumble. Not as much in quantity as Kr5, but far from neutral
So I could describe the sound signature of the IEM overall (and very simplistically) as reference+bass, with, I'd guess, more of a sub-bass emphasis than mid-bass.
With all these impressions, bear in mind that I was listening to it immediately after listening to Kr5 (they were both on the table in front of me).
So if I hear it as having an elevated bass as opposed to neutral, that's even after having just listened to the Kr5, if that makes sense!
You know (I'd assume!) how if you go from (e.g.) Dorado 2020 or EXT to most other IEMs, they might sound a bit anaemic in comparison until your brain has time to adjust
But that wasn't the case going from Kr5 to the Storm.
Would have to hear again to give anything more detailed.
But I can simply say that I listened to it, and was very impressed. This doesn't happen to me often, even with other flagship level gear. It just sounded to me like one of those IEMs that you'd guess are among the elite ones out there.
NB: I was listening using a Nayparm-hardware-modded Sony ZX300 and an iFi Gryphon (sound tweaking functions engaged and disengaged).
My impressions are based on that combo with sound-tweaking functions disengaged.
Listening to rock, pop and acoustic tracks.
I feel you and I have very similar taste in IEMs, based on what I've read of your preferences so far - hence why I'm inclined to trust your judgement of the Trifecta more than others that I've read, simply because your descriptions and tastes (e.g. with EXT and Dorado 2020, amongst several others) matched my own experience and thoughts.
So again, take that with a pinch of salt, but just putting it out there, for what it's worth
