The decoding and amplification stages work in perfect synchronization, significantly enhancing resolution and dynamic performance. An independently powered digital supply and low-noise positive/negative voltage design effectively reduce interference, delivering a clean, immersive soundstage.                                                                                High Output Power with Ultra-Low Distortion                Despite its miniature size, the JM98MAX delivers a robust 195mW of output power into a 32Ω load (THD+N &lt;1%). This ample headroom drives a wide range of earphones and headphones with authority. It achieves an ultra-low THD+N of just 0.0003% and an exceptional 110dB SINAD. With a signal-to-noise ratio of 125dB and a vanishingly low noise floor of 1.3μV, the JM98MAX ensures a pristine background and accurate reproduction of even the most delicate musical details.                                                                                Three-Level EQ for Personalized Tuning                A built-in three-level EQ switch puts fine-grained tonal control at your fingertips. Short-press once to cycle through modes: Balanced Original Mode (yellow indicator) delivers a neutral, comfortable tuning ideal for classical, jazz, and pop; Low Frequency Enhanced Mode (cyan) adds impactful bass punch for EDM, hip-hop, rock, and gaming; High Frequency Enhanced Mode (pink) brings out articulate vocals and crisp treble detail, perfect for female vocals, instrumental, and acoustic music. Each mode is carefully voiced to expand your listening experience without compromising signal integrity.
