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.
- 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.
- Magni 3+: choose this one if you want an all-discrete headphone amp. Discrete means its made up of lots of individual transistors (well, actually a lot of paired matched transistors now). It’s essentially a mini speaker amp. In fact, the topology is exactly that of a 2-stage speaker amp now, since we added a driver stage and Vbe multiplier for biasing. The driver reduces distortion and the Vbe multiplier means the bias is more stable. It's a super-advanced amp, and we’re very proud of it.
- Magni Heresy: choose this one if you want a 100% op-amp-based headphone amp that delivers spectacular measurements. Thank the high-quality op-amps used: OPA1662 for gain, OPA1688 for output—eight (8) OPA1688 stages per channel, for low output impedance and very high current capability. With these advanced parts (the OPA1688 even uses feedforward in its topology), we’re getting 6-8dB lower THD+N than Magni 3+, which is already 10-15dB lower THD+N than Magni 3.
"Let me wrap up this review with a few quotes. The first is “Good audio is getting cheap, and cheap audio is getting good” and this is becoming very true. It is in my opinion extremely hard to get an amp that sounds this good cheaper. In fact, I don’t think you can buy any amp new cheaper that’s on par with the Heresy.
