## Description

TOPPING L50 NFCA Headphone Amp SE/BAL Input 6.35mm 4 Pin XLR Output 3500mWx2 Mini HiFi Desktop Home Audio Amplifier (Black)

## Features

- ►New NFCA circuit► Newly designed new NFCA circuit based on the same working principle as the one in the A30 Pro. It offers twice the power at 300 Ω compared to the L30. The new circuit has the same extremely low noise of 0.3 uV and the dynamic range of 145 dB and 0.0006% THD + N.
- ►Easily adapt to high or low sensitivity► L50 has three gain options. The coverage of a wide gain range is enough to meet the needs of full-size, low-sensitivity over-ears to high-sensitivity IEMs. With the help of extremely low-noise 0.3uV, even IEMs don't hear any background noise
- ►Wide headphone impedance adjustment range► because the L50 meets the needs of several ideal amplifiers at the same time, it leads you to break through the inertia thinking when choosing amplifiers: from now on you don’t have to have amplifiers based on the impedance of headphones, everything you do need to do is choose L50 and then pick your favorite headphones, L50 can easily power them well
- ►Input Pass Through► When shutting down, the input signal is output directly to Cinch or TRS without amplification, which is more suitable for working with active speakers / monitor speakers if the DAC has a preamplifier function
- ►TOPPING E50 will be the best DAC for TOPPING L50► E50 and L50 have fully matched design languages and styles, and signals can be symmetrically transmitted via TRS, E50 uses sub-flagship chip ES9068AS, supports PCM, DSD, MOA decoding
