Effect Audio Grand Maestro Anniversary Limited Edition In-Ear Monitors
This product is available to pre-order with an ETA of mid November.
The Grand Maestro Anniversary Limited Edition (GMA) represents the zenith of our craftsmanship and innovation, celebrating the esteemed legacy of FATfreq's Tribrid Flagship - the Grand Maestro within our Maestro series.
At the core of the GMA lies a newly upgraded low-frequency dynamic driver with Basscannon v2, working in harmony with a meticulously re-engineered gold-plated bass resonance chamber. This combination unlocks a bass response that is deeper, more visceral, and richly textured, while retaining absolute control and separation. With our new Resoflow Quad EST system, treble reproduction is exceptionally smooth—free from harsh peaks or unwanted resonances—resulting in an airy, refined top end. This also enhances midrange clarity, creating a sound signature that feels both powerful and effortlessly natural.
A defining feature of the GMA is its compatibility with our NOAH tuning modules, allowing users to tailor the sound to their preferences. Every unit includes the standard Blue (Balanced Bass) and Black (Bass Power) modules and an exclusive Superstage Module, specially designed for the Anniversary model. This limited edition module features a gold-plated brass resonator plate and is tuned to expand the perceived soundstage, offering a unique sense of openness and dimension. Also included is our new limited edition Silver 'Reference' module. This module tightens the low end and reveals microdetails for a true reference sound signature — ideal for critical listening, mixing, and mastering, while still preserving the musicality and depth of your mix. Experience holographic and life-like sound with GMA's built-in vocal boost switch for a total of 8 expertly-tuned frequency curves.
The chassis of the GMA is precision-machined from aerospace-grade titanium, providing superior strength without sacrificing comfort or weight. To further enhance durability, it is reinforced with a Diamond-Like Carbon (DLC) coating, providing added protection against wear and corrosion. The faceplate is crafted from gold-plated brass, not only adding a touch of visual elegance but also enhancing the acoustic resonance for a richer, more refined sound. Each package comes packaged in a bespoke collector’s exhibition case featuring removable inserts and an integrated dehumidifier to keep your IEMs safe from moisture and performance ready, especially for long-term desktop storage.
