This characteristic makes it an ideal partner for critical listening, ensuring the amplifier adds virtually no distortion or noise to the audio signal.

Know before you buy
This Magni Heresy is in excellent, like-new condition. It has been used for approximately 100 hours and shows minimal signs of wear.
The amplifier comes with its original factory power supply. No additional cables or adapters are included.
The unit features a standard 6.35mm (1/4-inch) output jack. You can use most full-sized audiophile headphones directly, though you may need an adapter if your headphones use a 3.5mm plug.
The Magni Heresy uses RCA inputs on the rear panel. You will need an RCA-to-RCA cable or an RCA-to-3.5mm cable depending on your source device, such as a DAC or a computer.
While the amplifier works perfectly with most setups, the previous owner noted an incompatibility with one specific audio interface. It is recommended to ensure your interface supports standard RCA line-level outputs.
