Ten years ago, we introduced the first Magni. Since then, we’ve been refining and improving the line, to the point where Magni is now the only affordable, true no-excuses headphone amp and preamp. It’s literally the only headphone amp you’ll ever need.
No Excuses—Across the Board No excuses. Not in design, with discrete and advanced op-amp designs on the table. Not in parts, from its high-spec, sorted potentiometer to high-end thin-film resistors and silicon capacitors. Not in looks, with an all-new steel chassis using advanced stamping techniques. Not in safety, with new protection systems help protect your best headphones. And not even in manufacturing, with USA suppliers and Corpus Christi, Texas production.
Exotic Discrete Design…or Insane Measured Performance Magni+ is the only affordable headphone amp that offers a exotic, current-feedback, all-discrete design—for the same price as our Magni Heretic, an op-amp design with a unique topology that gives you even more insane measured performance.
Choose Magni+for the ultimate expression of an affordable all-discrete headphone amp—for hundreds less than other discrete designs (including our own!)
Choose Magni Hereticfor insanely great measurements from a unique op-amp topology that includes no overall feedback and a massively paralleled feedforward output stage. Or if you like red--Magni Heretic has a red bottom chassis.
Total Confidence for All Headphones Both Magni models offer three gain levels, including negative gain, to span all of your headphone needs. Use power-hungry planars…or super-sensitive IEMs. We’ve also incorporated a decade of learning in protection systems. Don’t worry about plugging your favorite headphones into Magni—included overcurrent and DC protection help ensure they’re totally safe.
Create a Complete Desktop System All Magnis include preamp outputs. This means you can connect any Magni to your desktop powered monitors for a complete system—or even connect it to a speaker power amp and use it as a preamp.
Designed and Built in Texas By “designed and built in Texas" this is what we mean: the vast majority of the total production cost of Magni—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. In the case of the Magni family, the chassis are made in California, the PCBs are made in Nevada, and it all comes together at our Corpus Christi, TX facility.
