Details

Topping L50, performance and power in spades

The Topping L50 is a desktop format headphone amplifier, with optimized architecture for perfect sound performance.

It incorporates the so-called new generation NFCA circuit, identical to the one used in the A30 Pro. It stands out for its versatility, with good power reserves and a gain setting that adapts to all types of helmets, even the most demanding.

Tailor-made NFCA circuit

In NFCA circuit and amplifier stage, it allows the L50 to develop considerable power, increasing what its predecessor L30 already did, at an impedance of 300Ω.

This design achieves a very low noise floor of only 0.3µV, a dynamic range of 145dB and a THD + N of 0.00006%.

Designed to fit

The Topping L50 has balanced and unbalanced connections to accommodate all sound sources.

It has an unbalanced RCA and a balanced 6.35mm TRS connector as input. Regarding the outputs, we get a balanced 4-pole XLR and a standard 6.35mm jack.

For the most demanding headphones

This Topping L50 adapts to the most demanding headphones thanks to its gain control and its three options. This function is useful to cover a wide gain range and work with EMI and high impedance headphones.
