Pros & Cons
Pros
- ✓ Dual AK4493S DAC chips in parallel for lower noise than single-chip rivals
- ✓ Runs on any 5V source: PC USB, phone charger, or power bank
- ✓ Discrete LNRD circuit holds the noise floor under 1.5uV
- ✓ Remote volume from -99dB to 0dB drives active speakers without a preamp
- ✓ Optical and coaxial inputs handle 24bit/192kHz consoles and disc players
Cons
- ✗ Optical and coax cap at 24bit/192kHz, far below the 768kHz USB ceiling

Key Features
- 👍 Supports high-resolution audio ▶️ TOPPING 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.
- 👍 Coaxial and Optical also has 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.
- 👍 5V power supply,anytime and anywhere ▶️ E30 II uses DC5V for power supply, which can easily access almost everywhere. You can power it up by USB port of PC, mobile phone charger or even a power bank. The built-in protection circuit will protect the E30 II and prompt on the screen after connecting to the wrong power supply.
- 👍 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 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.
- 👍 Pure DAC & DAC+Preamp application ▶️ E30 II is able to fix to maxmum output level so that it can be worked as a pure DAC. E30 II has built-in volume control function that can adjust the volume from -99dB to 0dB by using the remote control, so you are able to directly connect E30 II to power amplifier or active speakers, and control the volume of E30 II through remote control.
