Fiio FA19 VS 7th Acoustics Supernova

Youtube Video Summary

Fiio FA19 brings a premium feel: a sturdy, slightly translucent shell with visible BA packs, comfy fit, and a plush eight-wire cable that terminates in 4.4mm. The MMCX sockets aren’t ideal, but the shell is vented, holds tips well, and the magnetic case feels upmarket. Sonically, this 10-BA set leans warm-neutral with a rich, cohesive presentation—male vocals sound full, some female vocals come off a bit husky, and bass has quantity more than tightness. There’s a touch of 5–6 kHz energy and slight hiss; treble is clean and pleasant rather than showy. The bass switch mostly bumps mid-bass; the lower setting keeps things tidier. Overall it’s Fiio’s most well-rounded tuning to date, just shy of “exceptional” because of that soft mid-bass and a mildly flabby midrange.

Versus peers, FD15 sounds more neutrally tuned (if less special), while all-BA options like Supernova feel more natural and controlled down low. In the wider field, sets like Letshuoer Mystic 8 (a bit of a sleeper), ThieAudio Monarch MK4 (cleaner upper-mids, dual bass settings), ZiiGaat Luna (tighter, crisper for far less money), or even budget-friendlier picks such as YU9 can offer a stronger value proposition. At around $1,000, FA19 earns a solid recommendation for those who enjoy a warmer, airy BA take—graded roughly A4 / S-—but it’s a demo-first purchase and shines much brighter if found used around $300–$400. Not a new benchmark, yet a very good Fiio with treble finesse and a smooth, easygoing signature that many will simply enjoy.

Youtube Video Summary

Custom-built shells and faceplates make Supernova feel special from the start, and the ergonomics seal the deal: a light, durable shell, super comfortable fit and a supple, well-textured stock cable. The tonality stays open, clean and free of sibilance, with imaging that snaps into place both horizontally and vertically. Detail retrieval in busy scenes is immaculate, making it superb for long gaming sessions—not to farm K/D ratios, but to elevate the overall experience as in-game micro-details sparkle. Tip rolling works well (SpinFit, Divinus, Latex H70), though the included tips are decent; the clamshell case is nice, if a bit annoying to twist shut.

Versus peers, Supernova shows almost perfect tuning with exceedingly strong technicals and a touch of juicy, lush timbre. Against Night Oblivion Butastur, the overall tone and bass texture on Supernova are a hair better, while Butastur gets you 95–98% of the way for less and shines for classical and pop. Compared with Monarch Mk III, the FR curves are scarily close (within a couple dB), yet Supernova’s treble refinement and stage feel a tad more convincing, even if Monarch brings different technical strengths. Net takeaway: a holographic, genre-agnostic performer that’s easy to recommend; the only real caveat is the long wait time to get one, and the bass could use a touch more authority.

Fiio’s FA19 brings a lavish unboxing at a $1,000 ticket: a premium case, a magnetic cable tie, cleaning and MMCX tools, and a mountain of ear tips (silicone sets, dual-flange, foams, full SpinFits, and HS18). The cable uses swappable terminations executed cleanly, though it’s a bit stiff, and the MMCX hardware rotates freely. The clear resin shells feel dense and well-finished, with a small nozzle and a medium fit that’s comfortable but not very secure—the MMCX rotation often requires a nudge to keep placement in the ear. Inside are 10 BAs per side and a tuning switch that Fiio markets as “monitor” vs “hi-fi.”

On the ear, FA19 reads as a warm, dense V-shape even in the so-called monitor mode. The switch simply means “more bass” vs “a lot of bass,” lifting the entire low end for thickness but yielding drone and blur rather than punch or texture—described as farty, flat-backed bass. Up top there’s sparkle, but treble control is lacking, pushing sibilance on vocals and cymbals; stage is fairly narrow and imaging unremarkable, though mid/upper-treble lift can tease out some vocal grain and breath. Against a key rival, the 64 Audio U4s (with M12), the Fiio feels outclassed: U4s offers tighter, better-balanced bass, a more neutral midrange, and non-fatiguing treble with enough extension to stay lively. Verdict: despite stellar accessories and build, FA19’s tuning and technicals don’t justify its price; not recommended at $1,000—and there are stronger options even far cheaper.

Hand-built in Indonesia with customizable abalone faceplates, Supernova feels like a boutique step up in value: a handsome, slightly medium-large shell, stable fit, strong isolation, and a tasteful, beefy copper cable. The only nit: a smooth nozzle with no tip notch means soft tips can slip. Overall execution—build, comfort, and the personal order-to-chat experience—delivers a “next level” vibe uncommon around $750.

Tonally, this is a clean, body-intact neutral with a touch of sub-bass lift and a tasteful push in the lower treble. Midrange is the star—full, natural, and richly timbred without the hollow lower-mid dip of leaner targets. Treble is well-extended, linear, and textured, giving transients snap without tipping into sibilance. Technicals impress: tight bass attack, clear separation, precise imaging, and strong micro-contrast that keeps dense mixes like The Cure’s “Disintegration” organized and alive. Caveats are mild: listeners sensitive to lower-treble energy should note its presence, and the low end—while punchy—still reads as BA bass with less sub-bass “flutter” than a dynamic driver.

Against peers, Supernova blends the fuller midrange charm of Moondrop Blessing 2 with the technical grace of Moondrop S8, yet sounds more natural than either. Symphonium Meteor offers bigger bass and a lush stage but trails in separation and mid texture; S8 feels smoother with even stronger 3D imaging but less body. Taken together, Supernova’s tuning, texture, and boutique fit/finish make a compelling all-rounder—and an easy five-star recommendation, especially for those who value lifelike mids and crisp, controlled sparkle over maximal slam.

Fiio FA19 arrives as a true kilobuck treat, pairing monumental bass impact with high-end finesse. A 10-BA array (including custom bass drivers), a clever negative-feedback system, and an audio-grade crossover deliver deep, clean low end without clouding the mids—male vocals stay forward, natural, and ultra-clear. Up top, cymbal work has sparkle, air, and detail yet remains smooth and sibilance-free, while separation and layering feel studio-grade. At $1,000, this tuning reads as resolving, fast in attack/decay, and unmistakably fun.

For pure performance, the FA19 brings pinpoint imaging, beautiful depth perception, and a wide, well-ventilated stage that elevate both music and play. The bass toggle dip-switch can push sub-bass and mid-bass into downright addictive territory; switching it off reins things in for a more reference-leaning balance. Even against strong mid-tier contenders, micro-detail and retrieval step up a notch here—airy treble textures, subtle room cues, and layered backgrounds all come through with ease.

Competitive gamers get a standout edge: Valorant tracking feels “wall-hack” precise, Call of Duty benefits from immersive LFE without masking cues (especially with the switch off), and Rainbow Six Siege showcases clear vertical and positional info. The only caution is that the switch-on mode can be a touch sub-bass heavy in titles like Apex; otherwise this is an A-tier pick for the Wall-Hack Certified list—an analytical beast that blends clarity with grin-inducing punch.

Youtube Video Summary

Supernova’s calling card is its treble: extended, butter-smooth, and startlingly even. No peaks, no weird dips, no BA glare—just airy shimmer with spot-on decay that stays stable at any volume. It rivals the best under $1K and even brushes the Symphonium Helios (OG) for finesse, yet remains less bright and more relaxed. Despite being all-BA, there’s no BA timbre. Dynamics feel controlled rather than fiery—big chorus swings (think “Run Away With Me”) are rendered cohesively without harshness, trading adrenaline for refinement.

The low end is clean, tight, and well-separated—not a sub-bass sledgehammer. Sets with DDs like Hype 2, EJ07M, or Monarch dig deeper and rumble harder, but Supernova’s bass gives body without smearing. Vocals sit mid-forward but not shouty, a hair warm from mid-bass/1.5k lift; extension around ~3k could use a touch more presence for extra “head voice,” yet the overall presentation remains natural and unfatiguing and scales beautifully with volume. Versus Moondrop S8, Supernova trades a bit of the S8’s clinical separation for fuller mid-bass weight and more textured, even treble; the S8 keeps a leaner, clearer stage and more vocal gain.

Comparisons sharpen its profile: against EJ07 (OG/KL), EJ07 offers darker tonality and stronger sub-bass immersion, while Supernova is airier and smoother up top. ThieAudio Monarch series: Mk1 has snappier vocal clarity, Mk3 hits harder with bass texture/slam, but Supernova wins on treble quality and macro-smoothness. Neon Pro can feel more engaging at mid volumes with firmer low-end and crisper imaging, whereas Supernova shines when cranked, remaining composed and immersive. Net take: an “endgame”-leaning, balanced all-rounder for those wanting refinement over fireworks—genre-agnostic, not a treble-head blaster or bass cannon, and short on “special sauce” theatrics, yet consistently excellent where it counts. Availability is the real enemy; production scarcity makes it hard to snag.

Youtube Video Summary

7th Acoustic Supernova brings a 6BA setup at around $850, dressed in pretty shells but a bit bulgy for the fit. Packaging quirks and micro-print gripes aside, the included Versus Audio cable (permanent 4.4) looks flashy and feels premium. Tip rolling from Dunu SS to Render shifts the presentation, but the core signature stays smooth to a fault—vocals sit a touch further back, treble hints at a lift then fades with different tips, and only the occasional techno track shows bass that carries well. It’s the kind of tuning that’s impeccably polite yet tip-dependent and rarely grabs attention.

Across sources—from a warmer Alpha Pro chain to other amps—the Supernova keeps a straight face: competent, clean, and ultimately boring for the price. Against known yardsticks (neutral “glass-of-water” sets, bass-heavy options, or value champs like Kiwi’s Astrals), the Supernova doesn’t carve a clear identity; it’s smooth without the thrill. Final takeaway: lovely looks, nice cable, but the sound feels meh at this tier—barely meeting the bar where musical moments should pop. On the value meter, the cable helps, the tuning doesn’t; there’s been better—and for less.
