Douk Audio H5 Tube Preamp with LPF / HPF

A Natural Partner for A5: H5 is designed to visually and sonically complement the A5 amplifier, sharing a compact black HiFi look while adding tube warmth, MM phono input, tone control, and refined subwoofer integration for a richer, more complete stereo system. Flexible Phono and RCA Input: Use MM Phono for MM turntables and RCA Line In for DACs, CD players, streamers, computers, and more. The 20Hz HPF helps tame unwanted vinyl rumble, keeping record playback cleaner, steadier, and more controlled. Dual Outputs with Subwoofer Control: Dual RCA outputs let H5 feed two amplifiers or powered speakers at the same time, making it easier to expand your HiFi setup. SUB Out with 180/250Hz LPF helps reduce boomy overlap with main speakers for fuller, cleaner, better-integrated bass.
