Topping E30 II DAC Preamp - DAC for USB/Coax/Opt Inputs RCA HiFi Stereo Digital Audio Decoder(Sliver)

Supports high-resolution audio, delivering enhanced performance and improved reduction capability compared to a single chip. Coaxial and optical inputs support up to 24bit/192kHz audio, suitable for digital turntables, disk players, set-top boxes, and game consoles, enabling traditional equipment to produce a new sound. The Digital Processing module offers improved compatibility over the E30. Utilizes a 5V DC power supply for versatile use. It can be powered via a PC's USB port, a mobile phone charger, or even a power bank. A built-in protection circuit safeguards the unit and provides an on-screen prompt if an incorrect power supply is connected. Features a Discrete LNRD (Low Noise Reference Driver) circuit. This technology filters noise from various 5V power inputs and delivers a stable, ultra-low noise reference-level power supply, resulting in a noise floor lower than 1.5uV. Operates as a pure DAC with a fixed maximum output level. It also functions as a DAC+Preamp with a built-in volume control adjustable from -99dB to 0dB, allowing direct connection to power amplifiers or active speakers with volume control
