Schiit Magni Heretic: 120dB SINAD Headphone Amp & Preamp (2400mW, Black)

Meet Schiit Magni Heretic, the latest chapter in the brand's journey toward affordable, no-excuses headphone amplification. Building on a decade of refinement, Magni Heretic blends careful engineering with a rugged steel chassis and US-sourced parts produced in Corpus Christi, Texas.

No excuses apply across the board. The design uses high-spec sorted potentiometer, thin-film resistors, silicon capacitors, and a modern chassis stamping process to keep things reliable and quiet under load. Safety features are present to help protect your headphones even during long listening sessions.

Precision engineering you can hear

Magni Heretic uses a unique op-amp topology that reports excellent measurements without global feedback, paired with a massively paralleled feedforward output stage. The result is a clean, open sound with confident dynamics across a wide frequency range.

• Unique op-amp topology with no overall feedback for a transparent signal path
• High-spec sorted potentiometer and quality thin-film resistors
• Silicon capacitors chosen for stable, low-noise performance
• New steel chassis with advanced stamping for a solid, compact footprint

Designed for all headphones

Three gain levels, including negative gain, cover a broad range of headphones—from power-hungry planars to ultra-sensitive IEMs. Protective circuitry adds confidence, helping to guard your gear during everyday use and at volume peaks.

• Three gain levels including negative gain for flexibility
• Protection systems guard against overcurrent and DC faults
• Compatibility with a wide variety of headphones and sensitive sources

Build a complete desktop system

Magni Heretic doubles as a preamp, with preamp outputs to drive powered monitors or to feed a separate speaker amplifier. A standard 115 VAC USA plug keeps setup straightforward in the United States, Canada, and Mexico, while noting it is not designed for 220–240 V regions.

• Preamp outputs for desktop monitors or external amps
• Can be used as a preamp in a larger audio chain
• 115 VAC USA plug; ideal for US/Canada/Mexico environments

In short, Magni Heretic offers a compact, capable desktop solution that invites you to explore your headphones with clarity and control, without promising dramatic guarantees—just possibilities.
