Holy moly, Mjolnir 2 is now a tube amp? The previous one was solid-state. Are you manic-depressive or passive-aggressive or just indecisive?
No. We really, really like tube hybrid amps, because they provide the best possible combination of the strengths of tubes and the strengths of solid-state. So, we decided to make this unique, circlotron-topology headphone amp with tube gain and MOSFET output.

Okay. Let’s move on to the single-ended outputs. I thought you said Mjolnir couldn’t have single-ended outputs! What gives?
A circlotron has no inherent single-ended output. However, the circlotron outputs can be summed together, which is what we did here. Just like Ragnarok. Except lots cheaper. Shoot us for making Mjolnir 2 more flexible.

Do the single-ended outputs put out as much power as the balanced outputs?
No. They’re limited to about 2W into 32 ohms. Which is still plenty for most headphones.

Are you saying you also finally put some switches on the front of this thing for input switching and gain? I’ve been asking for that, for, like, forever.
Yep. Repeat after me: development improves the breed.

Hey, this thing runs warm!
Yep, just like Asgard 2.

So, is this really a balanced amp, or a fake balanced amp, or what?
Hey, don’t blame us for other manufacturers' abuse of terminology. When we say “balanced, differential,” that’s exactly what we mean. There’s no side-whispering going on about “Well, yeah, after we convert it to single-ended, then back to balanced again.”

What the hell is a Circlotron, and why do I need it?
“Circlotron” was the first commercial name for a cross-shunt push-pull output stage. At the time, it used tubes. We use MOSFET outputs, so we call our topology Crossfet™.

Crossfet™? Are the FETs angry?
No. They’re thrilled. N-channel MOSFETs and P-channel MOSFETs usually don’t match too well (and that’s putting it mildly.) Crossfet allows us to use only N-Channel MOSFETs, for better matching, and for an elegantly simple output stage with great performance.
