TOPPING E30 II DAC (Apos Certified Refurbished)

Back and better than ever The second generation of the TOPPING E30 DAC is here. The E30 II makes significant improvements over its predecessor. With dual upgraded DAC chips, it achieves better SINAD, SNR, dynamic range, and noise level. Plug and play Turn your PC into a HIFI source just by connecting it to the E30 II with a USB cable. It has a wide range of compatibility: Windows 10, Windows 11, Mac, Linus, iOS, and Android can plugged and played. 24-bit coaxial and optical performance Breathe new life into your digital turntable, disk player, and game console. Plug them into the optical and coaxial inputs and enjoy 24-bit/192kHz audio. Ultra-portable 5V power supply The E30 II uses a DC5V power supply, making it one of the most portable desktop DACs on the market. You can power it with a mobile phone charger, a power bank, or even the USB port on your laptop. A built-in protection circuit will prompt you whenever you’ve connected it to the wrong power supply–and save the E30 II in the meantime. Discrete LNRD  5V power supplies are historically noisy, which is why TOPPING has implemented a discrete LNRD (low noise reference driver) circuit into the E30 II. This circuit filters out various noises of the 5V power input, effectively lowering the noise floor to <1.5uV. Pure DAC application In pure DAC mode, the E30 II lets the DSD signal bypass the DATT Soft Mute and ∆E Modulator to provide pure/direct DSD performance.  DAC + Preamp application Use the built-in volume control function to adjust the volume from –99dB to 0dB. Directly connect the E30 II to a power amplifier or active speakers and control the volume with the remote control.
