DAC/AMP HARDWARE

The JCALLY JM6 Pro uses the Conexant CX31993 DAC chip paired with a MAX97220 headphone amplifier, delivering clean, low-distortion output suitable for most IEMs and earbuds. It supports PCM up to 32-bit / 384 kHz, ensuring high-resolution playback. With an SNR of ≥124 dB, low THD+N, and excellent crosstalk control, the JM6 Pro provides a clear, noise-free signal even with sensitive earphones. Despite its compact size, it delivers stable power and a smooth, natural sound signature.

SOUND CHARACTER

The JM6 Pro aims for a clean-neutral presentation—tight bass, transparent mids, and crisp but controlled treble. It enhances clarity and separation without altering your earphone’s original tuning. The MAX97220 amp helps maintain warmth and fullness, making the DAC musical yet accurate. Its noise floor is minimal, pairing well with both budget and premium IEMs.
