Magni 3+ raises the bar even higher for affordable headphone amps, with by far the highest output power in their price class-at least 200% higher than any competitor. At the same time, it provides the cleanest measured performance of any Magni, ever.

Not Just a "Starter Amp"
Magni 3+ is 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, Magni 3+ has tremendous power reserves. Combined with low distortion, an exceptionally low noise floor, and switchable gain, it performs far beyond its price.

High Performance
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.

Magni 3+ is the ultimate expression of an affordable all-discrete current-feedback headphone amp. It's now seriously a mini speaker amp, right down to the driver stage and Vbe multiplier.

Versatility Comes Standard
Magni 3+ includes preamp outputs. This means you can connect either one 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.

Designed and Built in California
The majority of the total production cost of Magni 3+--chassis, boards, assembly, etc.--goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal.

2-Year Warranty
Magni 3+ is covered by a limited warranty that covers parts and labor for 2 years.
