Topping E50 comes as a direct upgrade to the highly-acclaimed Topping E30 DAC system with improvements in every department starting with its core DAC chipset. The latest E50 is equipped with ES9068AS Sabre DAC that provides high-quality audio signal decoding achieving ultra-low distortion and high SNR ratings, ensuring high-quality sound output for its users. Topping E50 also brings support for MQA decoding along with 32-bit/768kHz PCM and native DSD512 decoding support. It supports selectable USB+Coaxial+Optical input modes and RCA+TRS output options.
Topping E50 uses CPLD processing to process the clock and optimize the digital signal achieving incredible jitter suppression capabilities. With this new CPLD processing, there is no need for an extra femtosecond crystal or an external clock to reduce the jitter.
Topping E50 supports an automatic on/off function, it automatically turns on and is set to the input where a valid signal is found. When no signal is provided for about a minute, the E50 turns off automatically.

Along with the latest E50 Desktop DAC, Topping has also launched its latest balanced headphone amplifier Topping L50.
L50 is an NFCA Headphone Amplifier featuring both single-ended 6.35mm and balanced 4-pin XLR headphone output ports. L50 has a tremendously powerful output with ratings of up to 3500mW x2@16Ω, at 300Ω, it outputs 540mW x2 which is more than enough to drive even the most demanding headphones without any trouble. The amplifier offers three-step gain settings, High, Medium, and Low. It also offers a pass-through bypass mode to connect the L50 with active/monitor speakers when DAC has a pre-amp function.
Topping has redesigned the NFCA Circuit for the latest L50 headphone amplifier. It is based on the same working principle as the A30 Pro and is capable of providing twice the power of L30 at 300Ω impedance. It is optimized to deliver clean high-quality amplification to the audio signal while maintaining ultra-low distortion and high SNR, Dynamic range ratings. Topping L50 achieves 0.3uV ultra-low noise and 145 dB high dynamic range as well as 0.00006% THD+N ratings.
With the help of a three-level gain switch, users can easily use their sensitive as well as demanding headphones with the Topping L50. The L50 has an ultra-low output impedance of <0.1Ω, so users won’t notice any background noise or hiss even with sensitive IEMs/headphones.
