Schiit Audio Mjolnir 3 Headphone Amplifier

By real Class A, this is what we mean: pure single-ended Class A, as in, the Class A that defined Class A, the Class A that can’t go out of Class A, the Class A everyone wants you to think about when they’re talking Class A. 

 

As in, Mjolnir 3 is also a no-feedback amplifier. Or, if you’re in the mood, you can switch in feedback. Because audio is about choice. 

 

Dual mono means that the left and right channels on the Mjolnir 3 share nothing, except the same circuit board. Each channel has its own power supply, including discrete regulation, separate choke, and separate transformer. And the choke input itself is a super old-skool way of power supply smoothing and energy storage, unlike anything else out there.

Mjolnir 3 employs a super-simple, complementary-pair, discrete balanced differential topology we call Equipoise™. And we mean discrete, right down to the power supply—no IC regulators here. And by balanced, we mean balanced, for real, from input to 4-gang pot to output—no conversion. 

 

Mjolnir 3 is so utterly overengineered that it uses two Gjallarhorn heatsinks (as in, heatsinks usually used in a speaker amp capable of delivering 30W into 4 ohms) and 32 10A-rated output devices (yes, thirty-two, 10 amp rated devices) to drive your headphones. At the same time, it provides the convenience features you want, like switchable gain (without feedback), balanced and single-ended inputs and outputs, and switchable preamp outputs.

 

By “designed and built in California' this is what we mean: the vast majority of the total production cost of Mjolnir 3—chassis, boards, transformers, 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. Our transformers are made in NorCal. You get the picture.
