Dunu Glacier VS Goldplanar GL-AMT16

The Dunu Glacier delivers a technically impressive listening experience with its nine-driver tribrid setup (1DD+4BA+4EST). The stainless steel shells feel substantial yet remain comfortable for extended sessions despite their weight. Sonically, it presents a Harman-inspired tuning enhanced by significant sub-bass rumble and a notably wide soundstage, creating an expansive presentation.

Bass response is a standout, offering deep, textured rumble and strong physical impact thanks to the biocellulose dynamic driver, while the four EST drivers provide highly detailed treble without harshness. However, the upper mids can occasionally feel intense or forward on certain tracks, and the midrange sometimes exhibits a slight hollowness, making it less forgiving of poor recordings. While the soundstage width is exceptional under $2000, depth and layering don’t quite reach the absolute top tier.

At $1349, the Glacier justifies its price with a premium unboxing experience, including a versatile modular cable, multiple high-quality eartip options (Dunu S&S, Candy, SpinFit), and a distinctive design. It’s a strong choice for those seeking a dynamic, detailed signature with thunderous bass and a vast stage, though its revealing nature and shell size may not suit all listeners or genres.

The Goldplanar GL-AMT16 is a single-driver in-ear using a 15.5 mm full-range AMT transducer (16 Ω, 102 dB) in a lightweight aluminum shell and ships with replaceable acoustic nozzles that meaningfully alter tonality. Its MSRP sits at $1,499, positioning it well into flagship territory. Specs and design details are documented by retailers and product pages.

On balance, the GL-AMT16 trends toward a neutral-bright, lean presentation with very fast transients and extended upper treble—traits consistent with AMT technology. Bass is controlled and clean but does not deliver dynamic-driver “slam,” so listeners wanting weighty low-end may find it restrained; pairing with a warmer source can help. Owner reports also note it is more chain-dependent than purely power-hungry, and that nozzle/filter choice substantially impacts perceived clarity and pinna-gain behavior.

Technically, the set excels in resolution, imaging, and separation, offering an open, airy stage and precise positional cues, while macrodynamics and bass physicality are more modest. The adjustable nozzles make it unusually configurable for a single-driver flagship, but it still reads as a specialist for acoustic, orchestral, and detail-centric listening rather than a do-everything all-rounder. Prospective buyers should weigh its unique AMT timbre and speed against the high price and genre selectivity.

Reveals every detail in your music, both the good and the bad. Exceptional bass, ethereal treble, remarkable clarity, and outstanding detail. The upper mid-range might be a bit too much for some people.

Clean, balanced but engaging sound, clear vocals, great midrange and tech. Vocals can be a bit too forward/sharp. The most recent unit I got sounds different than the earlier ones which was bass-boosted diffuse field.

GoldPlanar GL-AMT16 is a rare IEM built around a full-range AMT (Air Motion Transformer) driver—a 15.5 mm ultra-thin folded diaphragm that, by design, moves a lot more air than a typical dynamic driver.

Tonally, the AMT16 leans toward clarity and openness rather than heaviness. The treble and upper-mid regions are the standout: strings, cymbals and woodwinds show excellent harmonic detail, fine edges, and an airy backdrop. You get extension high up into the ultra-treble, yet it never feels overly sharp or fatiguing.

Mids present with good density—not too thin, not overly thick. Vocals sit slightly forward and articulate well: you can hear subtle breaths and mouth movements. Instrument separation and note definition are strong, thanks to the driver’s speed and control.

Bass is the one area where the AMT16 chooses restraint over brute force. Impact is present, but sub-bass depth or slam does not match the heaviest hitters. Because the bass decays quickly and doesn’t bleed into mids, the overall tonality stays clean and transparent.

Soundstage and imaging are impressive: the presentation feels spacious, natural, and unconfined. Instruments occupy clear space; layering is well-executed and gives a sense of air around the performance.

That said, some trade-offs: the sub-bass extension may not satisfy bass-heads who crave heavy rumble; also, the driver tuning and interchangeable nozzles require care

Verdict: The AMT16 is a technical masterpiece for listeners who value clarity, speed, imaging and treble extension over bass weight. It delivers a crisp, airy, refined soundscape—less about “slam” and more about musical transparency and detail.
