Description
Brand: AOSHIDA
Color: Silver
Characteristics:
- ★ New NFCA Circuit: Redesigned new NFCA circuit based on the same working principle as the one in the A30 Pro. It offers twice the performance at 300 Ω compared to L 30 as 0.0006% THD+N.
- ★ Easy adjustment to high or low sensitivity: L50 has three gain options. Covering a wide gain range is enough to meet the needs of everything from full-size over-ears with low sensitivity to high-sensitivity IEMs. With the help of extremely low noise 0.3 uV, even IEMs won't hear background noise.
- ★ Wide range of adjustment according to headphone impedance: Because the L50 meets the requirements of multiple ideal amplifiers at the same time, it leads you to break the inertia thinking in the selection of amplifiers: from now on, you don't have to choose amplifiers based on the impedance of headphones. All you need to do is choose L50 and then choose your favorite headphones, L50 can easily drive them well.
- ★ Input Pass Through: When powering down, the input signal is output directly to RCA or TRS without amplification, which is more suitable for working with active speakers/monitor speakers if the DAC has a preamp 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 transmitted balanced via TRS, E50 uses the sub-flagship chip ES9068AS, supports PCM, DSD, MOA decoding.
