Description
Singxer SA-2 Fully-balanced Headphone Amplifier The SA-2 picks up where the SA-1 left off: same pragmatic exterior but with radically upgraded internals. With doubled output power, lower distortion, and improved heat management, it’s a balanced headphone amplifier and preamp designed for those who like their music honest, detailed, and powerful.
Whether you’re running high-impedance headphones or sensitive IEMs, the SA-2 delivers the clean current and headroom to drive them all with confidence. More power to play with The SA-2’s output power boasts 10W into 32Ω, topping out at 15W into 20Ω.
That means effortless control and dynamic range even with power-hungry planar headphones. It’ll drive anything down to 8Ω without issue.
Distortion that barely registers Circuit optimizations and a new DC servo design bring the SA-2’s THD+N down to -117dB at 1kHz under an 8W load. Cooler heads prevail A copper block and aluminum alloy heat sink work together to pull heat away from the circuit.
The result is steady thermal performance even when you’re deep into a long listening session. Class-A sweetness At lower loads, the SA-2 runs in pure Class A, delivering that lush, harmonically rich tone that Class-A fans adore.
Above 64Ω, nearly all its output power stays Class A, smooth, full, and beautifully controlled. Gain staging done right Whether you’re using balanced or single-ended sources, the SA-2’s gain options keep things flexible.
Choose from low or high gain across configurations for the perfect balance between noise performance and drive power. Ultra-low noise floor At low gain, the SA-2’s noise floor measures just 500nV RMS A-weighted (20–22kHz).
Even the most sensitive IEMs will stay dead quiet between notes. Ground control A new GND/LIFT mode switch helps eliminate hum in complex systems.
If you’ve ever chased a ground loop through a chain of balanced gear, this small switch will feel like a big relief. 1dB What’s included SA-2 headphone amplifier Power cable User manual
