• Reference-Standard Professional Flagship Successor - As the worthy successor to the lllumination series, lllustrious continues to emphasise pristine bass reproduction while maintaining a smooth treble extension that meets the rigorous standards of professionals. Inheriting the 11mm patented high-performance dynamic driver from the lllumination, we have upgraded the diaphragm and magnetic circuit materials. improved manufacturing precision, and enhanced the acoustic front cavity design. This not only significantly improves frequency bandwidth and reduces nonlinear distortion but also further optimizes the smoothness of the mid-treble frequency response. 
• Legendary 11mm Patented Dynamic Driver - The legendary patented 11mm dynamic driver has consistently delivered T0-level performance in dynamic drivers. This is achieved through the use of ultra-high-efficiency magnetic conductive materials and a scientifically designed large-volume magnetic circuit structure that outperforms typical dual-magnet external magnetic circuits. A copper alloy independent support structure increases the stroke and minimizes disturbances in the magnetic circuit. The independent cavity structure, also made from copper alloy, helps adjust the driver's natural frequency and avoids interference with the magnetic circuit. 
• TAC Diamond-coated Dome Composite Diaphragm - Based on LCP dome technology, a high-rigidity artificial diamond layer is applied through a deposition process. This diamond layer, which features an SP3 bond significantly stronger than that of DLC material, enhances the rigidity of the dome. As a result, the material exhibits improved internal damping, leading to better treble performance with smoother extension and finer details compared to its predecessor. 
• Reference-Standard Low Distortion THD Less Than 0.03% - With advancements in diaphragm materials and driver technology, the nonlinear distortion of lllustrious is significantly lower compared to the previous generation of products. Odd harmonic distortion has been reduced to below 0.01%, providing a pure, natural, and clear high-quality sound. 
• 0.78mm Universal Interchangeable Cable Design - Includes replaceable plugs 3.5mm Single-ended /4.4mm balanced replaceable plugs.
