Mjolnir 2 is a unique, end-game headphone amp fully ready for any headphone, from IEMs to the hardest-to-drive planars.
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?
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?
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.
Hey, this thing runs warm!
Yep, just like Asgard 2.
So, is this really a balanced amp, or a fake balanced amp, or what?
What the hell is a Circlotron, and why do I need it?
Crossfet™? Are the FETs angry?
"Mjolnir 2 immediately impresses with its exceptionally low noise floor. This amp is super quiet and provides a spookily muted backdrop for low-level detail to emerge from, especially on the low gain setting which is so silent through over-the-ear headphones you would think you were in an anechoic chamber!"
"Mids are majestically mellifluous in tone yet remain very open, detailed and transparent. Highs are impressively extended, invigoratingly crisp and articulated with improved micro-detail distinction. The soundstage grows in all dimensions with instruments more clearly layered and spaced around the listener in an enveloping sphere of sound, giving a heightened sense of being at the epicentre of the performance."
"While the single-ended circuits are excellent, trading up to balanced elevates the performance to exceptional - and I dare say peerless - in this price range."
"Together, the two units complement each other exceptionally well and offer a seductively revealing, immersive and textured listening experience in which music is allowed to breathe freely. Their combined price-to-performance ratio verges on the ridiculous."
