I'd have to partly disagree on that. Reference is a fixed point, a standard of evaluation, that's the reason it's called reference. It's not based on majority opinion of what sounds good or bad. If you were in the studio when the track got laid down, that would be the reference. Anything else after that is colouration / skewed based on opinion, providing the technical capability is there.
Reference is such a miss-used term in hifi and stems from PR BS used years ago to distinguish TOTL product line from the "lesser" models. Most brands had "reference series" products but all had their own flavour (colouration in some form). These days reference usually implies a neutral tuning but the main aspect IMO is the technical ability of the gear, which as you've said isn't reflective of the curve. I'd go out on a limb and say most TOTL gear whether that be IEM / HP / DAP / main rig etc could be considered reference relating to today's terminology but each will add their own colouration (tuning).
A prime example that you personally can relate to would be Red. Absolutely 100% reference in terms of technical ability but like most transducers, most likely differ in tuning from original source.
Same goes for tuning transducers based on xyz amps which most manufacturers do. What differs between the product line isn't necessarily tuning / FR curve but technical merit.
That's what in this day and age reference is and it's a lot harder for transducers than amplifiers, as a 'true' amplifier technically has no colouration at all.
Anyway, beer time is over and time to get some sleep...
Exactly, exactly this.
Reference for tracks vs.
Reference for IEMs vs.
Reference for marketing are three very different things. To me, a reference track is a track you intimately know, which you can judge systems with. An ideal reference IEM is one that’ll “sound as different” (or carry over as little color) as possible with each track you play through it. And, reference in marketing is - more often than not - an ad for clarity and detail; not much else.
Speaking of, something I’ve noticed as my collection of self-made reference tracks has grown is they’re actually very ineffective for judging IEMs; for me, at least. Because, a mix and a master will go through so many iterations before publishing, that when an IEM makes them sound different, it won’t make them sound
wrong, if that makes sense.
So, for example, when I listen to one of my tracks with a bass-boosted IEM, my brain, rather than go,
“Oh, there’s more bass than there should be,” will instead go,
“Ah, sounds like mix version 6 when I put in a bit more low-end.” And, there are a myriad of differences beyond bass boosts too. I don’t know if it’s the same for any other producer/engineer here, but I’ve found it much easier to judge IEMs with tracks not of my own that I only know one, definitive version of.
The Elysian pair certainly doesn’t sell bass like the LX or EVO, but I have found that the source can change so much of what I hear -- the amp first, I'm still trying to figure out the current/voltage thing and what/how/why it does, then the DAC, Delta-Sigma or R2R, the Annihilator can sound like 2 different IEM! Curiously, that doesn’t happen with others I’ve tried, the Odin, Traillii, etc, I guess that’s attributable to the scalability of Annihilator. I never thought it was good for vocals and jazz, and like you, the bass wasn’t standout-ish but I was more than pleasantly surprised on my franken HM1K/Aroma power stack — a whole new ‘nother level, even the bass.
Wish you could hear it; the Subtonic boys had a listen and were quite impressed, exact words were 'never heard the Storm so good'. That's saying a lot coming from guys who design gear and have probably heard everything under Horatio's sky! IM(most)HO, amping is inexpensive (in the grand scheme of things) and make the most drastic improvements to your audio set-up. Not sure if you have a good amp; I hear the N8ii has a great LO, and how it leaps up a few notches being freed from having to internally power its DAC…
I agree with both you and
@aaf evo on this. Amps are one of the most fun links in the chain to play with, as they bring much more to the table than just tone-shaping. There are power and space-related traits to each amp, and shootouts of those can get pretty addictive. I’d second
@aaf evo’s notion, though, that, while inexpensive, a portable amp’s biggest toll is portability and convenience. I used to carry a Mojo stack for a while, than a KM-01 stack after that, and it became a hassle whipping out a whole brick just to switch albums or tracks. But, if you’re used to a backpack, or you’re just sitting at home, it is a joy, indeed.
