Shining Bright Like A Diamond: The Final Audio A10000 Review

Final Audio has long been a respected name among audiophiles, known for crafting premium in-ear monitors (IEMs) that blend innovation with sonic finesse. The acclaimed A8000 gained legendary status thanks to its pure beryllium diaphragm and breathtaking clarity. Now, Final Audio returns with the A10000, a new flagship IEM designed to push the limits of detail retrieval and high-frequency extension. Priced at $3,000, the A10000 arrives in both standard and limited edition variants and is positioned as a next-level upgrade to the A8000. I had the opportunity to spend time with this highly anticipated model—here’s an in-depth look at its build, sound, and technical prowess.

Aesthetics and Build Quality

Visually, the Final A10000 is a striking piece of industrial art. Its polished stainless steel shells exude premium craftsmanship, catching and reflecting light for a mirror-like finish. This heavier housing may surprise those familiar with the lighter A-series models, but the added weight feels deliberate—signaling durability and structural integrity.

The silver-coated cable complements the sleek design with a high-grade look and feel. Terminating in a 4.4mm balanced jack, the cable features proprietary MMCX connectors that are meant to remain in place. Final Audio has specifically engineered the A10000’s MMCX interface to discourage cable swapping, prioritizing optimal synergy with the stock cable. It’s worth noting that detaching the cable requires considerable force, so those who love to cable roll may find this design restrictive.

As for fit, the Fusion Type G eartips—first introduced with the S4000 and S5000—bring a new tuning profile and sealing method. While they offer improved sonic presence and warmth, they may not suit every ear shape. In my case, the Type G tips felt a bit firm. Thankfully, the included Type E tips provided a comfortable alternative, though they slightly altered the sound signature by narrowing the overall presence.

Listening Review

Soundstage & Imaging

The soundstage on the A10000 is expansive by IEM standards—realistic in depth and moderate in width. While not ultra-wide, it’s finely layered, allowing instruments to occupy well-defined spaces. Classical recordings benefit the most, especially orchestral works where instrumental placement and dynamics take center stage. For example, in pieces like Peer Gynt, the A10000 reveals delicate crescendos and transitions with impressive nuance and grace, highlighting Final Audio’s mastery in tuning for microdynamics.

The Final A10000 is unapologetically treble-focused, emphasizing upper-frequency clarity and air. This tuning lends itself well to genres that rely on sparkle and articulation—think classical, jazz, acoustic, and progressive rock. Bass takes a backseat here, offering lean support rather than rumbling authority. This makes it a dream IEM for detail-oriented listeners who favor an analytical presentation over visceral low-end impact.

Low Frequencies

Bass on the A10000 is subtle and restrained. It provides just enough foundation to prevent the overall tuning from feeling hollow, but it doesn’t thump or slam. Instead, sub-bass tones are tight, quick, and texturally clean—better for string basses or jazz kicks than electronic drops or hip-hop thumps. Rock basslines, for example, come through with a higher register twang, emphasizing texture over punch.

Interestingly, ear tip selection significantly influences the low-end response. The Fusion Type G eartips offer a warmer and fuller bass presentation compared to the more neutral Type E tips. However, pairing the A10000 with warmer-sounding DACs or amps—like the Mojo 2 or AK HC4—had minimal impact on the overall bass emphasis. This IEM simply isn’t built for bass lovers, but for those who appreciate tight, fast lows with a clear midrange transition.

Midrange Frequencies

The midrange is where the A10000 truly shines. Vocals are presented with forward placement and high-resolution clarity, especially in the upper mids. Instruments like guitars, pianos, and brass benefit from strong detail retrieval and separation. However, there’s a slight artificial edge to the tonality—think precision over lushness.

While the mids may not offer the most natural warmth, they deliver a technically excellent performance. Layering and articulation are strong, and every instrument in a busy mix holds its own space without smearing. This makes the A10000 especially effective for studio monitoring, acoustic recordings, or complex jazz arrangements.

High Frequencies

Treble is the highlight of the A10000’s tuning. The top-end is vibrant, extended, and airy, without veering into sibilance. High strings, cymbals, and chimes are rendered with pristine shimmer, making classical violins and jazz rides feel alive. The sparkle adds brilliance to tracks without becoming grating—though those sensitive to treble may find the upper register a bit intense over extended listening sessions.

What sets the A10000 apart is how smoothly it extends into ultra-high frequencies. There’s a sense of infinite space, particularly in minimalist or ambient recordings, where the IEM teases out subtle nuances that lesser earphones miss. This makes it a powerful tool for audiophiles who crave the tiniest sonic details.

Conclusion

The Final Audio A10000 is a masterclass in high-frequency tuning and technical detail. It’s not a bass-lover’s IEM, nor is it the most versatile all-rounder—but for those who crave clarity, soundstage depth, and shimmering treble, this IEM offers a uniquely surgical and rewarding experience. Its hefty build, proprietary cable, and selective fit options are worth considering, but the sound makes it one of the most compelling analytical IEMs currently on the market.
