Campfire Astrolith VS Starry Audio Yozora

The Campfire Audio Astrolith is a flagship dual planar-magnetic IEM using a 14 mm low-mid driver and 6 mm treble driver in a crossoverless design, positioned at around $2,199 MSRP. Its build marries a semi-transparent 3D-printed acrylic body with a polished stainless-steel faceplate and metal nozzles, yielding a robust yet relatively lightweight shell. Multiple reviewers note excellent comfort and isolation, with the smooth contours and moderate size allowing extended listening without hotspots.:contentReference[oaicite:0]{index=0}

Sonically, Astrolith is generally characterised as a warm, mildly V-shaped or rich W-shaped tuning, with deep sub-bass extension, prominent mid-bass and a thicker lower midrange balanced by crisp, extended treble. Technical performance is a major strength: reviewers consistently highlight top-tier resolution, microdetail, and a wide, airy soundstage with precise imaging that places it among Campfire’s most accomplished releases. At the same time, the elevated bass and darker tilt make timbre somewhat divisive, with some reports of mid-bass thickness, occasional upper-mid/treble unevenness and a strong dependence on tip and source pairing.:contentReference[oaicite:1]{index=1}

In practice, the Astrolith tends to shine with modern genres that benefit from physical, fast low-end and expansive staging, while remaining capable with acoustic material when carefully matched to a neutral, resolving source. From a value-for-money perspective, opinions are mixed: several writers view its build, accessories and technical prowess as competitive in the $2k bracket, whereas others argue that at $2,199 the asking price feels ambitious given its timbre quirks and strong planar and hybrid competition. Overall, Astrolith reads as a specialist high-end option for listeners prioritising impactful bass, soundstage and detail retrieval over perfectly neutral, universally forgiving tuning.:contentReference[oaicite:2]{index=2}

Starry Audio Yozora is a Hong Kong flagship IEM positioned firmly in the ultra-high-end bracket, using an 8-driver 2DD+6BA hybrid layout with a 3-way crossover and AROMA Audio’s 9.2 mm dual-coil dynamics dedicated to low frequencies. The shells are semi-custom-style 3D prints aimed at broad fit compatibility and come bundled with Rolling Force’s copper “Choco” cable, while the official price of roughly USD 2,169 / HKD 16,880 clearly positions it as a summit-fi offering rather than a value play.

Sonically, Yozora follows a warm, bass-emphasised tuning where sub-bass reach and mid-bass punch are clearly above neutral, but the dual dynamics are controlled well enough that midrange clarity and vocal focus remain intact rather than masked. Review measurements and listening notes describe vocals as relatively intimate and centre-focused, with treble that adds some sparkle and air without aggressive peaks, and a slight softening at the very top that favours fatigue-free listening over maximum brilliance. Technical performance is strong in terms of macrodynamics, bass texture and overall detail, while stage size and imaging are competitive for its class but not clearly class-leading versus the most expansive multi-kilobuck references.

From a value-for-money standpoint, the very high MSRP means Starry Audio Yozora is judged against other summit-fi monitors, and its appeal is strongest for listeners who specifically prioritise powerful low end, strong dynamics and close, impactful vocals over strict neutrality or maximum treble extension. Its comfortable fit, isolation and well-matched stock cable support long sessions, but the bass-forward, characterful tuning makes it less universally adaptable than more neutral flagships, so the overall assessment is of a coherent and engaging high-end IEM whose pricing and tonal focus narrow its target audience to a specific taste profile.
