Mini Valve Headphone Amplifier Stereo Audio Preamplifier for 4.4/6.35 Headsets

Dual-Mono Architecture: Each channel is powered by its own dedicated amplifier circuit, ensuring superior stereo separation and reduced crosstalk. Paired with a 200V high-voltage tube stage, the P5 headphone amp delivers rich, clean, and warm analog audio. This structure outperforms shared-path designs for a more immersive hi-fi listening experience. Versatile Headphone Outputs: Supports both 4.4mm balanced and 6.35mm single-ended jacks, making it ideal for studio headphones and audiophile setups. With an adaptive impedance switch, it automatically tailors gain levels (5dB/15dB) to match your headphone of 16–600Ω and unlock optimal clarity. .
