JCALLY JM6PRO II

Revolutionary Dual-Chip Architecture with Visual Identity

The JCALLY JM6PRO II represents a comprehensive evolution from the acclaimed JM6PRO, introducing a visible window design that showcases the internal DAC and amplifier chips. At its core, the Conexant CX31993 flagship DAC chip pairs with the Maxim MAX97220 secondary op-amp chip. This dual-core configuration unlocks the explosive potential of the DAC, delivering a leap in sound quality characterized by powerful resolution, expressive dynamics, and an immersive, natural soundstage.

High-Power Output for Demanding Transducers

The JM6PRO II delivers a substantial 70mW output power at 32Ω (THD+N <1%), an 18% improvement over conventional dual-chip implementations. This increased output effortlessly drives high-impedance earphones and headphones, ensuring stable, high-quality sound across a wide impedance range—from 16Ω to 300Ω. Whether paired with sensitive in-ear monitors or demanding over-ear headphones, the JM6PRO II provides authoritative dynamics and precise control.

Ultra-Low Loss Circuitry for Pure Fidelity

Engineered with an ultra-low-loss design, the JM6PRO II achieves industry-leading objective performance metrics. The signal-to-noise ratio reaches approximately 107dB (32Ω, A-weighted), while background noise is minimized to just 5.7μV—5% lower than competing solutions. Total harmonic distortion plus noise (THD+N) measures an exceptional 0.0030% at 32Ω, a 57% reduction that eliminates coloration and interference to reveal the true texture of original recordings. Crosstalk is suppressed to -71dB, ensuring superior spatial perception and precise instrument localization.
