Myth becomes reality
In search of the ultimate sound, the founders of EFFECT AUDIO, Suyang, and FATfreq's Benjamin poured their shared passion into the Grand Maestro Anniversary Founders' Edition. Limited to 200 pieces worldwide.
Everything that made the Grand Maestro Anniversary an icon remains: its eight sound tuning settings, its limitless resolution, its expansive soundstage, and the new Basscannon V2.0+ that enhances it even further. With an additional dynamic driver in an isobaric configuration, it delivers deeper, faster, and more controlled bass, providing a top-level bass experience that gives you the feeling of a live performance.
The experience is rounded out by ASCENDIUM, our flagship cable, which uses materials from the Centurion, Horus, and Beyond Limited Edition and offers the perfect balance between reference accuracy and musical engagement. The result is greater clarity, harmonic richness, and a deeply satisfying listening experience.
Founders' Note
"The Founders’ Edition is for those who believe that music should not only be heard but deeply felt. It is for those who see in sounds the same as we do – memories, emotions, and meaning.
For me, this edition is a milestone. Not only as the founder of FATfreq but also as someone who has always believed that audio, when done right, can be transformative. I hope the Grand Maestro Anniversary (Founders' Edition) gives you a piece of that transformation every time you press "Play."
Benjamin Tan / Founder, FATfreq
"At the heart of EFFECT AUDIO has always been the pursuit of perfection, that fleeting moment when the devices disappear and only the music remains. Collaborating with the FATfreq team was an inspiring journey where we jointly pushed the boundaries of what an IEM experience can be, whether it's the rumble of sub-bass, the lift of soul-touching airy vocals, or the glide of silky highs."
Based on 16 years of experience in cable manufacturing, ASCENDIUM was created: made from materials and geometries worthy of a flagship, and designed to bring out the nuances and unique personality of the Grand Maestro Anniversary Founders’ Edition (GMA FE). For me, GMA FE is a tribute to this shared passion: sound, design, and perfection made tangible. I couldn't be prouder of what our teams have created, and I invite you, our greatest supporters, to lose yourself completely in it.
Zou Suyang / Founder, EFFECT AUDIO
New Basscannon V2.0+
Double power. Double impact.
Introducing: Basscannon v2.0+ – a next-generation bass powerhouse equipped with a brand-new Dual Isobaric Dynamic Driver configuration.
By coupling two precisely tuned dynamic drivers in an isobaric arrangement, we have significantly improved low-frequency performance while maintaining absolute control.
Look forward to a deeper extension, denser sub-bass, and an even more powerful slam, while maintaining the precision and speed that made the original a stage favorite. The enhanced chamber architecture ensures clean layering and separation, prevents bass overlap, and keeps your mids intact.
Designed for bass lovers, live musicians, and studio professionals who crave maximum authority in the low-frequency range – this is bass, evolved.
ASCENDIUM
