Firehawk FX headphone out electronics in Firehawk Posted September 5, 2016 Hi there, Does anybody know what kind of DAC and/or amp is behind the headphone out jack on the Firehawk FX? When I connect the Firehawk to my computer via USB and play AIFF for FLAC files from iTunes, the music has much more clarity, instrument separation, and clean power than just plugging headphones straight into my iMac headphone jack. Jamming with my favorite songs is a very high sound quality experience. I use Sennheiser HD598 headphones, so that helps. Because the result it similar to using a dedicated USB DAC/headphone amp combo, I just wondered what's in the Firehawk that makes it sound so good. Anybody know? Or is that a trade secret?
