Headphone Amp Comparison

	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 More Information	Cyrus soundKey soundKey is an award-winning revolution in mobile music.

Cyrus quality audio is now available to everyone. $99.00 MSRP More Information
