Overview
The JCALLY × Crinacle AP6 represents a new benchmark in portable audio performance,
designed in collaboration with renowned audio reviewer and measurement specialist
Crinacle.
Developed to deliver exceptional power and precision in a compact form factor, the AP6
stands as JCALLY’s most powerful DAC-amplifier to date. With up to 540mW of balanced
output power (16Ω load), it confidently drives demanding headphones whilst maintaining
superb detail, clarity, and control.
The AP6 introduces a dual-output Conexant CX31993 DAC architecture, the first of its kind
in this category, enabling simultaneous 3.5mm single-ended and 4.4mm balanced outputs
with remarkable efficiency. Complemented by dual SG Micro SGM8262 opamps, the AP6
achieves both high current output and low distortion for a refined, transparent sound
signature.
Encased in a sleek, anodized aluminum body, the AP6 combines minimalist industrial design
with robust durability, offering premium build quality and portability for everyday
audiophile use.
At under US$40, the AP6 redefines what’s possible in entry-level hi-fi—offering a reference
grade sound signature crafted and tuned in partnership with Crinacle.
