Elysian Annihilator 2021 VS Subtonic STORM

Youtube Video Summary

Subtonic STORM arrives as a spectacle: a limited run of 50 units presented in a hefty suitcase-style box that feels close to 2 kg. The unboxing greets with a personalized card and serialized plate—in this case marked “STORM 019.” Accessories are equally premium: a neatly organized tip case and a Singaporean handmade leather pouch crafted from aged Italian leather, signaling boutique attention to detail before the earphones even leave the case.

The earpieces show off a golden “stormy” faceplate evoking mythic cloud imagery, backed by hand-enameled black paint so meticulous that one in three plates is discarded to meet quality standards. Even the stock cable is positioned as ultra-high end, quoted at around $2,500 with an intricate crystal-lattice design. Price is acknowledged as “way too much money”, yet the presentation unabashedly stakes a claim as the world’s best IEM. This video stays focused on the unboxing and build; a full listening review is teased for a later date.

Subtonic STORM closes the list as the ultra-high-end, “one-and-done” pick—the kind of most expensive flagship that needs no hype because the name says it all. Chosen for a “versatile” roundup, it’s framed as the endgame option for those who want a single IEM to cover everything and have the budget to match—cue the playful “rich boys” jab.

The verdict is equal parts praise and pragmatism: demo first. STORM isn’t a blind-buy, and the price is so stratospheric it gets the tongue-in-cheek advice to sell a car, a house, or a kidney. In short, a summit-fi statement piece with serious one-set potential—but only after making sure the tuning truly clicks.

Elysian Annihilator 2021 arrives as a boutique flagship from Malaysia with a clear resin shell, gold faceplate, and uncommon Pentaconn Ear connectors. Inside sits a Foster dynamic for bass, four BAs for mids, and dual Sonion ESTs for treble. The tuning skews bright V-shaped: engaging yet potentially intense for treble-sensitive listeners. Bass is mid-bass tilted with punch but comes off dry and compressed, and persistent driver flex detracts at this price bracket.

The midrange is where the technical muscle shows—exceptional resolution and clarity with a slightly digital edge to timbre. Treble is the headline: a rare, proper EST implementation that’s blazing fast, captures microdetail effortlessly, and uses a subtle ~6 kHz dip to make upper harmonics materialize with immediacy. Extension feels remarkably linear into the air region, delivering space and sheen without veering harsh, provided one isn’t hypersensitive up top.

On technicalities, this set plays in the top echelon: detail retrieval rivaling (and in midrange, surpassing) usual benchmarks like U12t, impressive width and openness, and uncompressed macrodynamics. Trade-offs exist—note weight and transient density are lighter, hurting coherency and lending a slightly raw character. Value is tough at multi-kilobuck, but as a showcase of speed, extension, and treble mastery, Annihilator 2021 earns a spot among the few IEMs that genuinely feel world-class.

Brushed titanium Elysian Annihilator (2021) comes dressed to impress: a slick presentation with SpinFit tips, a plush micro-suede case, and a flashy gold cube 4.4 cable termination. The shells are crystal clear, showing off a 7-driver tribrid layout (1 Foster dynamic, 4 BA, 2 EST) in a four-way crossover, rated at 22Ω. The cable is beefy and terminated in Pentaconn Ear at the IEM side—sturdier than MMCX, but not the most convenient for aftermarket swaps. Price is a gut-punch: $3,000 (plus a little extra for the titanium finish), which sets expectations sky-high before a single note plays.

Sonically, this thing is an information firehose. Micro-details, ambient cues, and the “stuff between the notes” pop into focus with an airy, ultra-resolved presentation that separates elements like they’re each in their own display case. It’s engaging and never boring, pushing “one more track” syndrome hard. Bass is tight and competent but not a sub-bass thunder god, and it’s not the undisputed champ of every category; instead, the signature leans on clarity, layering, and treble finesse to deliver a different, highly technical flavor that stands apart from more “natural” single-DD favorites.

Value talk gets spicier. Price-to-performance keeps it from “perfect score” territory, even though overall quality screams top-tier. Think halo car logic: breathtaking in its lane, not a universal daily driver. The takeaway: a fantastic, fun, high-end tribrid that excels at resolution and air, memorable for how it sculpts space and detail—just don’t expect it to demolish every rival on bass slam or justify its cost purely on rational math. Call it a deserved 9/10 on enjoyment and execution, with the sticker price as the only real annihilator.

Youtube Video Summary

Elysian Annihilator 2021 presents a highly balanced yet distinctly treble-forward tuning: energetic upper mids paired with world-class treble that delivers striking clarity, microdetail, and separation without veering into fatigue. Elements in the mix stay cleanly delineated, producing a “technical monster” character that prioritizes transparency and precision. Bass is good—tasteful and supportive—but clearly not the centerpiece.

Against the 2023 revision, the 2021 model keeps its edge in midrange clarity, while the newer set adds bass texture and physicality with essentially the same excellent treble. The choice is preference: pursue the 2021 for its crystalline definition and speed, or lean 2023 for a touch more realism down low. Given the small delta in overall quality and strong demand for the 2021, sticking with it remains a very safe and arguably more “reference-leaning” play for those who prize resolution above all else.

Most IEMs inevitably introduce flaws that shatter musical immersion—be it harsh treble, shouty vocals, or unbalanced bass. These imperfections act as chains, binding the listener and preventing that elusive state of pure, uninterrupted freedom within the music. While the OG EJ07 came close, even it faltered on certain tracks, its forward vocals becoming a jarring distraction when pushed hard. The Subtonic Storm, however, shatters this pattern entirely.

Contrary to its name, the Storm represents the eye of the hurricane—a sanctuary of pure, effortless sound. It liberates the music from tuning flaws, presenting it naturally and tranquilly. There are zero distractions or attachments holding the listener back, enabling deep introspection and complete immersion, as if conversing directly with the singer or instrument. This profound, intangible quality—achieving that free state—is why it's considered the best IEM, offering unmatched resolution, separation, and imaging, albeit at an astronomical $5,000 price point.

Value-wise, the Storm is undeniably terrible; the KZ ASF ($250) gets you 80% there, and the Monarch MKII ($1,000) delivers 95%. It's a luxury item, justified only by its unique, unmeasurable ability to dissolve worldly distractions and forge total oneness with the music. Crucially, it's not for everyone: Bass heads, background listeners, or those enjoying J-pop/K-pop/EDM will find far better value elsewhere under $300. Only those deeply seeking musical transcendence, with ample disposable income, should even consider it. For everyone else, stay away—you simply don’t need it.

Youtube Video Summary

Subtonic STORM lands as a $5,200 flagship built around novel SLAM balanced-armature tech: the dual BA “subwoofer” and “woofer” are separated and crossed over independently, joined by a regular BA mid-woofer, additional BA mids, BA mid-tweeter and tweeter, plus two EST—nine drivers total with a seven-point crossover. The result isn’t just another spec sheet; it’s a system that behaves like a rethought low-end engine that sets up everything above it.

On music, the bass ranks an honest 8/10 because it doesn’t sound like typical BA bass—there’s real weight without mid bleed, so male/female vocals, strings, and guitars stay pristine. Complex tracks reveal studio fingerprints: the 38 Hz triple drop on Big Boi’s “Kill Jill” slams; the glockenspiel in Springsteen’s “Born to Run” is crystal; Pink Floyd’s “On the Run” left-right sweeps and the early gate announcement snap into focus; Hendrix’s uneven production becomes obvious; and the Led Zeppelin IV kick-drum intro hits with the produced, swirling authority it should. From Vivaldi to hip-hop, it just handles the library.

Stage is spacious and speaker-like off good sources, with positional cues that outclass sets like Elysian Annihilator and even edge the Fatfreq Grand Maestro for resolution, stage, and tonality—though Grand Maestro’s multi-tuning keeps it competitive. Ignore treble “hacksaw” graph takes and target-chasing; the performance argues against strict adherence to Harman-style curves. Diminishing returns are real, but for those chasing something genuinely different, the STORM’s reworked BA low end and refined EST top end deliver a uniquely authoritative, all-genre presentation that’s hard to unhear.
