Mjolnir 3, when it hits, will be accompanied by something like the "15 Magnis" chapter. It took a long time for me to come up with something we liked. We tried a bunch of approaches, including Nexus/Continuity/Programmable OPS, tube hybrid, all-solid-state-tech-forward, etc...and ended up with something that's a bit of a left turn. It's closest to the Freya+ buffer stage topologically, but with some Mjolnir 1 DNA, and with a bunch of things we've never done before: true dual mono, choke-input, discrete-regulated supplies, ultra HV front end, real Class A with switchable SE or push-pull operation, switchable no overall feedback, switchable gain.
It's still huge for a desktop amp, it's extremely heavy with 4 48VA core transformers/chokes inside, and it puts out an insane amount of heat. This is real, no-fooling Class A, like the original Asgard, not high-bias Class AB or Continuity. It won't be for everyone. And it's still many months out. Maybe summer. We'll see.
