LYREMAN X021 Portable Headphone DAC Amplifier ES9039Q2M 32bit 768kHz DSD512
The Lyreman X021 is a portable DAC equipped with an ESS ES9039Q2M chip and two SGM8262 amplifiers, capable of decoding PCM streams up to 32bit / 768kHz as well as DSD512. Its 4.4mm balanced output delivers up to 522mW into 32Ω, allowing it to drive both sensitive earphones and more demanding headphones.
Compatible with iOS, Android, Mac and Windows, it combines a USB-C input, two headphone outputs, 3.5mm jack and 4.4mm balanced, as well as a 100-step volume control. Its visual and touch interface makes control easier on the go, while its design allows it to be integrated into both a portable source and a sedentary listening setup.
Lyreman X021: ESS ES9039Q2M DAC
The Lyreman X021 is a portable DAC based on an ESS ES9039Q2M chip, paired with two SGM8262 amplifiers in order to deliver up to 522mW into 32Ω at the balanced output. This architecture supports PCM streams up to 32bit / 768kHz as well as DSD512, allowing high-resolution recordings to be reproduced with precise separation and good dynamics.
Lyreman X021: Versatile headphone amplification
The X021 adapts its power to different types of headphones thanks to two separate outputs: an unbalanced 3.5mm jack output, delivering up to 130mW into 32Ω, and a 4.4mm balanced output, capable of reaching 522mW into 32Ω. This design allows it to drive both sensitive in-ear monitors and more demanding headphones, while maintaining a stable reproduction.
Lyreman X021: Connectivity and compatibility
Its USB-C input provides the connection with a smartphone, a tablet or a computer, while iOS, Android, Mac and Windows compatibility makes its integration into different listening setups easier. The SPV5048 Pro audio controller supports the USB 2.0 interface, decoding up to 768kHz / DSD512 and display management, in order to ensure a stable transmission and synchronized control.
Lyreman X021: Volume control and integrated interface
The Lyreman X021 features a 100-step volume control, allowing a gradual adjustment directly from the device. Its interface combines a visual display with physical controls, in order to monitor active settings and control playback without relying exclusively on the source device. This layout improves its use on the go as well as in a desktop setup.
