DX1 II vs L50 NFCA Specs
Core Functionality
The DX1 II serves as a complete desktop solution, combining a DAC, DSP processor, and headphone amplifier in one chassis. It features an ESS ES9039Q2M DAC chip and supports PCM up to 384kHz and DSD256. The L50 is a dedicated headphone amplifier that requires an external digital-to-analog converter. It utilizes a new NFCA circuit design to deliver power, but it does not include a built-in DAC. If you need a single unit for digital input and amplification, the DX1 II covers both roles. The L50 is best suited for systems where you already have a quality DAC or want to pair it with a specific source like the TOPPING E50.
Power Output
The L50 provides significantly higher power output, rated at 3500mW per channel. This allows it to drive high-impedance headphones and low-sensitivity over-ear models with ease, offering twice the power of previous models at 300 ohms. In contrast, the DX1 II outputs 1000mW x2 at 32 ohms. While sufficient for most IEMs and many headphones, it is less powerful than the L50 for demanding loads. The L50 also features three gain options to adapt to various headphone sensitivities, ensuring compatibility with both high and low sensitivity devices without background noise. For maximum power, the L50 is the stronger choice.
Connectivity Options
The DX1 II offers versatile connectivity for modern setups. It includes USB-C and optical inputs, along with 4.4mm balanced, 3.5mm, RCA, and optical outputs. This allows it to connect to PCs, consoles, and active speakers. It also supports UAC 1.0 and 2.0 for plug-and-play compatibility with gaming devices like PS5 and Nintendo Switch. The L50 focuses on audio connections, featuring SE and BAL inputs and 6.35mm and 4-pin XLR outputs. It lacks digital inputs, relying on an external source. The DX1 II provides more flexible connection options for different devices.
Gaming Features
The DX1 II is tuned for gaming with a 10-band PEQ DSP. You can customize sound profiles for footsteps, positional cues, or music using the TOPPING Tune software. It includes a 3.5mm TRRS jack for gaming headsets with microphone input, supporting 24-bit/192kHz voice chat. The L50 does not include DSP or gaming-specific features. It is designed purely for high-fidelity audio amplification. If you need to adjust frequencies for gaming or use a headset with a microphone, the DX1 II offers these practical tools. The L50 is better for pure music listening without digital processing.
Noise Performance
Both units achieve extremely low noise floors suitable for sensitive IEMs. The L50 boasts an ultra-low noise of 0.3 uV, ensuring a silent background even with high-sensitivity in-ear monitors. The DX1 II achieves a noise floor below 0.9μVrms through a patented low-noise discrete power supply. While both are excellent, the L50 has a slight edge in specified noise performance. The DX1 II maintains low distortion at 0.0006% THD + N, similar to the L50. For critical listening with sensitive gear, both deliver clean audio, but the L50 specifies a lower noise value.
Which device fits your setup
Gamers needing EQ and chat
The DX1 II includes a 10-band PEQ DSP for tuning audio profiles. It supports UAC 1.0 and 2.0 for console compatibility. The 3.5mm TRRS jack handles voice chat with microphone input up to 24-bit/192kHz. This all-in-one DAC and preamp design simplifies your gaming audio routing.
Audiophiles seeking pure amplification
The L50 NFCA focuses on amplification with a new circuit design. It delivers 3500mWx2 output with 0.0006% THD + N. The ultra-low noise floor of 0.3 uV protects sensitive IEMs. Input pass-through allows direct signal routing to active speakers, making it ideal for a dedicated amp role.
Users wanting flexible connectivity
The DX1 II offers USB-C and optical inputs with multiple outputs including 4.4mm balanced, 3.5mm, and RCA. It supports PCM up to 384kHz and DSD256 decoding. The included infrared remote allows volume control without pairing delays, providing a clean desktop setup with versatile connection options for various source devices.
Those needing high power output
The L50 NFCA provides 3500mWx2 power output, which is double that of similar models at 300 ohms. It features three gain options to adapt to both low-sensitivity over-ears and high-sensitivity IEMs. The fully balanced SE/BAL inputs and 4-pin XLR output ensure robust signal transmission for demanding headphone loads.
