Douk Audio Ampapa H1 Headphone Amplifier

Description

• Power for Demanding Headphones: Built around a discrete Class A output stage, Ampapa H1 delivers strong current drive and up to 4000mW from its balanced high-gain output, giving 16–600Ω headphones wider headroom, steadier control and smoother dynamics. 4.4mm, 4-pin XLR and 6.35mm outputs fit more full-size HiFi headphone setups.
• Preamp Control for Your Audio System: With 2×RCA and 1×TRS analog I/O, H1 keeps your DAC, CD player and streamer connected for simple source selection, while its preamp outputs can stay linked to multiple power amps or active speakers for system expansion. Designed to complement Ampapa Q1 and D1, it adds tube preamp control for a more unified stack.
• Custom ECC83 Tube Character: Made with exclusive PSVANE × Douk Audio ECC83 tubes, H1 brings a warmer, richer tube character to both headphone listening and preamp output. The custom tube set gives H1 a more distinctive out-of-box identity, while tube rolling support leaves room to fine-tune the sound later.
• Effortless Control Across Your Setup: Low, mid and high gain help H1 match sensitive headphones, everyday models and harder-to-drive pairs with less guesswork. HP, Line and HP+Line output modes cover headphone, preamp output or both, while the 1.5-inch OLED keeps key status clear and 12V Trigger helps compatible gear power on/off together.
• Built for Refined HiFi Use: Japan NJW1195 volume IC keeps channel balance stable, while pluggable op-amps leave room for sound tuning. 0.04% THD+N and ≥113dB SNR support clean signal performance, and the low-noise relays, isolated tube power shielding and CNC aluminum chassis add quieter operation and lasting build quality for demanding headphone listeners or serious HiFi users.
