It’s okay.
Well, usually, I would be more enthusiastic, but:
- The overzealous patrons of this tuning rubbing in my face with their mythical 5128 rig and telling me what to prefer and how I should read my graph and how it’s a pivoting moment in IEM history and I should be in awe and grateful leave me a significant distaste for the whole tuning. Yes, it’s not logical; it’s against the spirit of science, yadda yadda. But I’m a human, first and foremost, despite my love for audio geekaroo.
- This target a description of what “flat” is. Achieving flat is good (when I’m in my geeky mood, I would say flat is “ideal tuning”), but does not mean the journey is done. Preference? Breakthrough in the treble evenness? Unlocking the ability to strictly control an IEM’s dynamic? Strictly control its soundstage and imagine? There are lots of things to do, but no, let’s say those are not important, not real, rather than accepting we have a way ahead of us.
- Taking away the distaste for the patrons of this target, I personally really like the incarnations of this target including Supernova, MagicOne, and 61t. Beautiful midrange. But again, we listen to the whole response at once, not just the midrange.
- BUT, one cannot blindly apply this target without considering the ability of the underlying IEM, IMHO. I tried to match a few IEMs to this target (or more specifically, to supernova’s response) and the results have been varying and generally middling. In my experience, we need an IEM with strong midrange resolution to not sounding veiled and muffled with this target (but of course, resolution is not real, as per patrons).
I will stick to Harman 2019 as the “frame of reference” line, and plain old 711 coupler as the “ruler”. Other than that, tuning IEM is a skill, and I’ll keep open eyes and ears. I love my graphs, but recent experiences tell me not to trust it more than a quick visual check.
All of this reminds me of the early days when I followed internet advice to AutoEQ my IEM and headphone and have to nod and say “what a nice tuning” when the harman pinna gain drill my skull like icepick, because “experts on internet” say this is how good sound is supposed to be.
