In Pursuit of the Pinnacle of Sound, Founder's of Effect Audio and FATfreq Pour Their Shared Passion into the Grand Maestro Anniversary Founder's Edition

• Limited edition, only 200 units worldwide
• Equipped with new Basscanon V2.0+ technology
• Includes an additional dynamic driver in an isobaric configuration
• Delivers deeper, faster, more controlled low-end
• New Ascendium flagship-grade cable

Myth, Made Real

Everything that made the Grand Maestro Anniversary iconic remains: its eight tuning settings, boundless resolution, expansive soundstage, and elevated it further with the new Basscannon V2.0+. Now featuring an additional dynamic driver in an isobaric configuration, it delivers deeper, faster, and more controlled low-end impact, delivering a truly endgame-level bass experience that brings the sensation of live performance to your ears.

Completing the experience is Ascendium, the flagship-grade cable that uses materials from the Centurion, Horus, Beyond Limited Edition, striking the perfect balance between reference accuracy and musical engagement. The result is greater clarity, harmonic richness, and a profoundly satisfying listening experience. 

New Basscanon V2.0+

Introducing the Basscannon v2.0+, a next-generation bass powerhouse equipped with a brand-new Dual Isobaric Dynamic Driver configuration. By coupling two precision-matched dynamic drivers in an isobaric layout, they've supercharged the low-frequency performance while maintaining absolute control.

Expect deeper extension, denser sub-bass rumble, and an even more visceral slam, all while retaining the tightness and speed that made the original a stage favorite. The upgraded chamber architecture ensures clean layering and separation, preventing bass bleed and keeping your mids intact. Designed for bassheads, live performers, and studio professionals who crave maximum low-end authority. This is bass, evolved. 

Ascendium

Every Grand Maestro Anniversary Founders’ Edition is accompanied by Ascendium, a bespoke cable born from Effect Audio’s vault of flagship-grade materials, each material personally curated by Suyang to unlock the IEM’s full potential. 

Ascendium features Palladium-Plated Silver, EA’s final reserve material, used only for limited editions, together with Gold-Plated Silver and rare noble alloys. With its mythic composition and unwavering precision, each strand channels the voice of the gods: thunderous dynamics, celestial clarity, and a harmonic richness that breathes soul into silence, awakening hidden dimensions within your music.

The custom Y-split design takes inspiration from a Maestro’s Scepter, a symbol of command and artistry. Its sculpted form, finished in a matching Champagne Gold color, pairs mirror-polished edges with a satin center, creating a striking play of light and shadow. At its heart, a titanium-black recess adds depth and dimension, elevating the design into a statement of regal precision.

Founder's Edition Exhibition Case

Each of the 200 Grand Maestro Anniversary Founders’ Editions arrives in a handcrafted wooden box, meticulously polished and finished with ten layers of piano lacquer, the same refined gloss found on high-end acoustic instruments. Its surface gleams with depth and resonance, much like the sound it holds within.

Open the lid to reveal the titanium earpieces, the Ascendium cable, and the leather carrying case, all elegantly framed in soft velvet. Blending art with meticulous craftsmanship, this presentation completes the luxurious experience of the GMA FE, a privilege reserved for only 200 owners worldwide.
