H3000

About the H3000

The Allnic Audio H-3000 is a high-end, dual-chassis vacuum tube phono preamplifier featuring fully transformer-coupled circuitry, LCR filters for precise RIAA equalization, and pure Class A operation with zero negative feedback. It offers four single-ended inputs (two MC, two MM), single-ended and balanced outputs, adjustable MC step-up transformer gains (22dB, 26dB, 28dB, 32dB), and selectable load resistors (10kΩ, 20kΩ, 30kΩ, 47kΩ). The design includes tube-regulated power supply, current meters for gain tubes, mute and phase switches, and Allnic's gel-damped tube sockets to minimize microphonics. It uses premium cores in transformers for low loss and wide bandwidth. Though succeeded by models like the H-7000, it remains available used and is not explicitly listed as discontinued by the manufacturer.
