YJCO D185 Flagship 2.1 Hi-Fi Integrated Amplifier

Description

The YJCO D185 is a flagship 2.1-channel integrated Hi-Fi amplifier designed to become the centrepiece of a modern desktop or home audio system.

Powered by dual Texas Instruments TPA3255 Class D amplifier chips, the D185 delivers impressive output power with excellent efficiency, low distortion and outstanding control over a wide range of passive speakers.

Digital audio performance is handled by the renowned ESS ES9038Q2M DAC, providing exceptional detail retrieval, natural vocals and precise instrument separation. Whether connected via USB, Optical, Coaxial or Bluetooth, every source benefits from high-quality digital-to-analogue conversion.

Wireless playback is driven by the Qualcomm QCC3084 Bluetooth 5.4 platform with support for LDAC, aptX HD, aptX Low Latency, AAC and SBC codecs, allowing compatible devices to stream high-resolution audio with excellent clarity.

Unlike conventional stereo amplifiers, the D185 also integrates dedicated subwoofer controls, allowing independent adjustment of crossover frequency and subwoofer output level for a more balanced listening experience.

Premium internal components, including Japanese ELNA audio capacitors, high-quality filter capacitors and a carefully separated circuit layout, contribute to stable performance and low electrical noise, while socketed operational amplifiers allow future upgrades for enthusiasts.

Completing the design are three analogue VU meters that combine classic Hi-Fi styling with real-time visual feedback, creating a desktop amplifier that sounds as impressive as it looks.

Whether you’re building your first premium Hi-Fi system or upgrading an existing setup, the D185 offers exceptional versatility by combining a high-performance DAC, Bluetooth receiver and powerful integrated amplifier into one elegant chassis.
