Topping E30 II DAC HiFi 2 x AK4493S Amplifier Direct Mode Decoder for USB/Coax/Opt Inputs Stereo Digital Audio Decoder PCM 32bit 768kHz DSD512 Native Black Cover
  • Coaxial and Optical Have Good Performance The optical and coaxial input of E30 II supports up to 24bit192kHz audio, which is suitable for digital turntables, disk players, set-top boxes, and game consoles, so that traditional equipment can also give a new sound. The Digital Processing module provides better compatibility than the E30.
  • Supports High-resolution Audio The E30 II uses two sub-flagship AK4493S chips of AKM's VELVET Sound technology. AK4493S is an upgraded version of the previous AK4493. Two AK4493S in parallel can achieve better performance and reduction ability than a single chip.
  • Discrete LNRD How to solve the noise problem of 5V power supply? The E30 II's answer is the Discrete LNRD circuit (low noise reference driver). The Discrete LNRD circuit filters out the noise of various 5V power input and provides a stable power supply of ultra-low noise reference level for E30 II. With this technology, the noise floor of E30 II is lower than 1 .5uV.
