SMSL H200 Balanced Headphone Amplifier Preamplifier

The SMSL H200 is a fully balanced audiophile headphone amplifier and preamplifier based on a discrete amplification architecture integrating four proprietary PLFC (Precision Linear Feedback Circuit) modules. This design achieves an ultra-low total harmonic distortion of just 0.00007% (THD+N), a 131dB signal-to-noise ratio, and a 131dB dynamic range. Powered by a custom toroidal transformer combined with a low-noise regulated linear power supply, the H200 delivers up to 5W into 32Ω through its balanced 4.4mm headphone output, allowing it to drive both sensitive in-ear monitors and demanding audiophile headphones. It features unbalanced RCA and balanced XLR analog inputs, as well as RCA and XLR preamplifier outputs for seamless integration into a HiFi system or active speaker setup. Three gain levels allow precise output adjustment for different headphones, while the relay-controlled volume circuit ensures accurate channel matching. Housed in an elegant CNC-machined aluminum chassis with a color IPS display and remote control, the SMSL H200 is a high-performance audiophile solution for both headphone amplification and high-fidelity preamplification.
