SINGLE ENDED CLASS A FET HEADPHONE AMPLIFIER
ZERO FEEDBACK | SINGLE VOLTAGE GAIN STAGE

Asgard is a fully discrete, Class A, single-ended FET headphone amplifier with no overall feedback and a noninverting circuit topology. Its high-current design makes it uniquely suitable for low-impedance headphones.

Now, if you’re an engineer, the preceding paragraph probably means something to you. For everyone else, let’s simplify it: Asgard will sound friggin tremendous on virtually any headphone you throw at it, from $39 cheapies to those $1400 monsters you’ve been wanting to try. Asgard will even drive them to ear-imploding levels, if that’s what you’re into. And Asgard will do this for years and years, with no maintenance or tube replacements.

Fully Discrete Topology
No op-amps, no shortcuts—Asgard is a fully-discrete, zero-feedback JFET/MOSFET circuit with discrete regulation and not one single IC in the entire amplifier.

Real Class A—No Joke
Asgard isn't one of these "pretend" Class-A amps that's really just a Class AB amp that runs in Class A some of the time. It's a real, true, single-ended, current-source-biased, can't-run-anything-but-Class-A amp. This means it runs warm. Plenty warm. But this is the way we get superb performance with no overall feedback.

5-Year Warranty
Asgard is covered by a limited warranty that covers parts and labor for five years. That’s 5 years. Yes. FIVE. Compare that to the competition.
