Headphone Amp Comparison

Schiit Asgard vs Cyrus soundKey

Schiit Asgard

Asgard 3 is a highly powerful, highly affordable, modular headphone amp and preamp that gives you a complete, single-box solution for all your desktop needs. It’s a re-thinking of the headphone amp that started it all (for Schiit, anyway—the original Asgard, introduced in June 2010, was our first product.) Asgard 3 features our unique Continuity™ topology that extends the benefits of Class A output, and accepts all the same modules as Jotunheim and Lyr 3.

$199.00 MSRP

Cyrus soundKey

soundKey is an award-winning revolution in mobile music. Hi-Fi streaming services like TIDAL mean fantastic quality is available to subscribers, but phones lack the necessary hardware to get the best from this data. soundKey unlocks that data, using our years of expertise in high-resolution DAC and amplifier design. Cyrus quality audio is now available to everyone.

I see it a step up from $9 dongles but the $99 price is hard to swallow.
