[Pre-Sale] Ampapa H1 Class A Headphone Amplifier 4000mW with TRS/RCA Preamp

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.
