Tonally good and works as an all-rounder. Very expensive for what it is now, treble recession may make it a bit boring for some. Other better & cheaper alternatives that are similar enough exist.

Demoed on Eletech Victoria cable (not stock). Very fleshed out stage with convincing depth. Strong imaging, layering, and res. Bass can use more body and decay.

As technical as a PMG SE but smooth like an RN6 (engaging mids) Flawless for my library
Youtube Video Summary

7th Acoustics Asteria arrives as a limited run of 77 units at around $3,800, presented in a numbered box with premium trimmings. The shells are described as the most beautiful seen in the hobby—shifting, almost bioluminescent blue caps with extended gold trim—and the fit is excellent thanks to a subtle wing. Under the hood sits a 10 mm dynamic driver plus 12 balanced armatures (latest-gen Knowles), with visible multi-tube routing and pressure relief to avoid insertion issues. The accessory suite feels purposefully upscale: a perfectly color-matched and supple cable (no gaudy branding), a structured case (noted as possible animal hide), Final Audio tips, additional tip sets, cleaning tools, stickers, and even a 4.4 mm to 3.5 mm adapter.

Sonically, Asteria is framed as reference-grade yet musical, with detail retrieval and resolution described as almost peerless. It handles a wide library with ease—classic rock, grunge, 90s hip-hop—and while some genres may benefit even more than others, overall performance is characterized as fault-free. Compared with similarly exclusive sets, it avoids the common “expensive but underwhelming” trap; the coherent tuning and technical chops deliver on high expectations without the need for caveats, making this a stunning aesthetic and acoustic package that feels every bit as special as its limited status suggests.

Pretty much the closest to a tonal panacea that I've heard only held back by the bass.
Youtube Video Summary

7th Acoustics Asteria prioritizes midrange and treble finesse with only one caveat: the bass isn’t the greatest, presenting a slightly BA-like character with a faintly “farty” mid-bass. The midrange is pure butter, driven by a gentle 2.5 kHz pinna rise followed by a subtle 3.5 kHz bump, keeping it forward yet smooth. A touch of presence around 200–300 Hz adds warmth, while the treble fixes Supernova’s lower-treble heat around 5–6 kHz and pushes extension past 15 kHz.

The result is a presentation that’s buttery yet detailed, with natural imaging and pinpoint precision that screams “godlike tonality.” Value is the sticking point: at roughly $3,800, the proposition isn’t as compelling as Supernova’s, and the overall performance feels closer to the ~$2,000 bracket. For listeners who prioritize tonality and imaging over bass texture and price efficiency, Asteria remains a compelling high-end choice.

The 7th Acoustics Asteria is a hybrid flagship built around a 10 mm dynamic driver for bass and twelve balanced-armature drivers covering mids through super-treble (5-way crossover), packaged in a CNC aluminum shell and paired with a bespoke LYRA cable. Retailers describe proprietary crossover and treble-loading implementations (EXP / ECHO) aimed at precise integration and high extension, and the run appears limited to 77 units. Pricing varies by market, but a common US MSRP is $3,800.

Tonally, Asteria targets a U-shaped balance: elevated, textured sub-bass, a mildly recessed midrange, and airy upper treble. Frequency-response references and dealer commentary support the emphasis on bass impact and treble “sparkle,” with vocals pushed slightly forward against a relaxed lower-midrange bed. This aligns with FR database traces showing boosted sub-bass and upper-treble energy relative to the center mids.

Technical performance is a core strength: imaging precision, separation, and macrodynamic slam are repeatedly noted, with stage size competitive among current flagships. The trade-off is a midrange that can feel slightly pulled back on timbre-critical content, and the ultra-premium price positions value as conditional on preferring this lively U-shape over neutral targets. Given its execution and cost, Asteria reads as a specialty end-game for listeners seeking visceral bass and airy treble without overt harshness.
