Latest-Gen AKM Velvet Sound DAC Chips. Topping E30 II is designed with a premium Dual DAC Chipset for high-resolution audio signal decoding. Topping has equipped the E30 II with two latest launched AK4493S DAC chips. These are from the AKM’s Velvet Sound Technology chipset, an upgraded version of the classic AK4493. Two of the AK4493S chips are arranged in parallel, one for each channel.
Premium XMOS USB Receiver. The USB input of Topping E30 II is handled by the trusted XU208 8-core USB processor from XMOS. It supports high-resolution PCM(up to 32-Bit/768kHz) and native DSD512 audio signals. E30 II also supports MQA decoding through the USB as well as other digital inputs.
Pre-Built DAC Filters. Topping E30 II includes various different digital filters for decoding. It has 6 pre-built filter modes for PCM decoding, and 2 pre-built filter modes for DSD signal decoding.
Pure DAC/Pre-AMP Functions. One can use the Topping E30 II in pure DAC mode where the output level is maxed out. In this mode, DSD signals bypass the DATT Soft Mute and Delta Sigma Modulator to provide a pure DSD performance.
Discrete LNRD Circuit. Topping E30 II works with a 5V power adapter. In order to reduce the noise issues with a 5V power supply, Topping has equipped the E30 II with a Discrete LNRD circuit(Low-Noise Reference Driver).
