7th Acoustics Supernova VS Campfire Audio Alien Brain

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.

Alien Brain arrives as a single-DD + 4BA hybrid around $1,000 with a truly peculiar shell: the rounded, “alien cortex” faceplate is magnetic, uses MMCX, and can be tricky to seat. The unboxing is lavish—two cables (including 4.4 mm), a compact magnetic leather case, a USB-C DAC/amp, foams plus “sticky” tips, cleaning tools, and extras. Fit is the hurdle; tip-rolling is essential, but once positioned correctly, comfort and seal fall into place.

Tonally, this set pursues a balanced, all-rounder tuning with a near-ideal bass shelf, lively but controlled upper mids, and sparkly yet composed treble. There’s punch and detail without drifting into fatigue; extension is strong, but staging isn’t the most expansive and note weight isn’t “thumpy”—this isn’t a bass-head cannon, more a clean, grounded presentation. The FR shows a touch of 1 kHz energy and smooth ripples through presence/air that favor natural timbre over hyper-etched brilliance, making it a long-session, non-fatiguing listen.

Versus Campfire’s own lineup, it’s far more normalized than the colorful Trifecta, better extended than the warm Axion, and closer in poise to Moon Rover but with a bit more bass and refinement. Compared to peers like Dunu Glacier or DA Mecca, Alien Brain trades V-shaped excitement for cohesive neutrality, and avoids the upper-mid glare that can scare off listeners. Net result: a strong recommendation for those who can manage the fit and want a high-end Campfire that does something new—not the classic house warmth, not sterile flatness, but a realistic, well-rounded signature with broad appeal.
