DISCRETE HEADPHONE AMPLIFIER | CLASS AB | HIGH OUTPUT

Magni is the only fully discrete headphone amp that is made in the USA. Delivering 1.2W of power into 32 ohms, Magni is ready for virtually any headphone—including many hard-to-drive orthodynamic models.

Discrete Design, DC Coupled
If you ain’t into engineering, you can probably skip this section. But it’s important. All other amps in this price range use op-amps for gain. Not Magni. It uses a discrete gain stage design, with low-noise JFET inputs, fast VAS transistors, and massive output power transistors. The result is greater current capability for higher power output. We’ve also used a DC servo to eliminate coupling caps from the signal path.

From IEMs to Orthos
Magni is quiet enough for many IEMs, but provides up to 1.2W into 32 ohms, which is plenty for many orthodynamic headphones. Magni is versatile enough to be a “do all” amplifier—it may be the only amp you ever need.

Made in USA
By “made in USA,” we mean made in USA. The vast majority of the total production cost of Magni—chassis, boards, assembly, etc—goes to US companies manufacturing in the US. Our board house is 20 minutes away from our office in Newhall. Our chassis guys are just over the hill in the Valley. 

2-Year Warranty
Magni is covered by a limited warranty that covers parts and labor for two years. That’s 2x the coverage of most amps in this price range.
