Schiit Magni 3+

This is no “starter amp.” Schiit Magni 3+ has the power, performance, resolution, and versatility to meet all your needs—no matter the headphone.

Magni 3+  raise the bar even higher for affordable headphone amps, with by far the highest output power in their price class and at least 200% higher than any competitor. 

Not Just a “Starter Amp”

Magni 3+ could be all the amp you’ll ever need, for any headphone. It has the power, performance, low noise, and versatility to meet all your needs. You’re set from IEMs to hard-to-drive planar designs. With a full 2400mW into 32 ohms, Magni3+ has tremendous power reserves. Combined with low distortion, an exceptionally low noise floor, and switchable gain, Magni perform far beyond it's price.

Your Choice: High Performance…or Even Higher

For Magni 3+, we pulled out all the stops in designing the highest performing discrete Magni ever, by any metric—power, distortion, or noise floor. But it’s easy to get even higher measured performance from integrated (op amp) designs, so we decided to give you a choice, with Magni Heresy. 

Choose Magni 3+ for the ultimate expression of an affordable all-discrete current-feedback headphone amp. It’s now seriously like a mini speaker amp, right down to the driver stage and Vbe multiplier. Magni 3+ is in our traditional silver and gray chassis.

Choose Magni Heresy for insanely great measurements from an all-op-amp based headphone amp that uses super high quality parts, including a multiple paralleled output stage with feedforward. Magni Heresy is in a black and red chassis.

Both amps sound fantastic. You really can’t make a wrong choice. 

Versatility Comes Standard

Magni3+ include preamp outputs. This means you can connect to your desktop powered monitors for a complete system—or even connect it to a speaker power amp and use it as a preamp. With its built-in time-delayed start-up and instant shut-down, there’ll be no glitches or pops through either headphones or speakers, either.

By “designed and built in California" this is what Schiit mean: the vast majority of the total production of the Magni—chassis, boards, transformers, assembly, etc—stays local. The chassis are made minutes from their facility. The PCBs are done in Nevada. Yes, the wall-warts are made in China, but there's some give and take at this price point. 

2-Year Warranty 

Magni3+ is covered by a limited warranty that covers parts and labour for two years.
