    Magni 3+ and Magni Heresy raise 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, they provide the cleanest measured performance of any Magni, ever. Go ahead. Compare these new Magnis to anything out there at the price, and we think you’ll agree: there’s really no competition.

    Not Just a “Starter Amp”
    Either Magni 3+ or Magni Heresy are all the amp you’ll ever need, for any headphone. They both have 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, either Magni has tremendous power reserves. Combined with low distortion, an exceptionally low noise floor, and switchable gain, both Magnis perform far beyond their 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
    Both Magnis include 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, either.
