To ensure we get the best out of these headphones, we are using Schiit’s agship amplier, the Ragnarok, as well as its agship DAC, the Yggdrasil, to power these headphones. The Ragnarok is a solid state amplier that is well suited for driving power-hungry planar magnetic headphones because of its bottomless reserves of power. It is capable of delivering a staggering maximum of 10W per channel into 50 ohms. The Yggdrasil, on the other hand, eschews o -the-shelf delta-sigma DAC chips in favor of medical grade digital to analog chips that run o Schiit’s proprietary digital lter. The key benet is that unlike delta-sigma DACs which up samples the original samples, the Yggdrasil handles PCM les natively and retains all of the information of the original sample le. For purists, this means their music is untainted.
