I want Hank Williams Jr to perform just because he ' s American as fuck and it ' s a big fuck you to the NFL <| sep |> Usually best to start of with a solid state amp like a Magni 2 or an O 2 because they ' re cheap , solid , and powers almost everything . Though in your case something like a FiiO E 10 K would work well the K 712 isn ' t a very demanding headphone . A dac might not be needed for you , so just pick up an amp and see how that goes . If you have a noise floor or audio out issues , then you would really want a dac . Otherwise , it comes down to how resolving the headphones are , and if you would get any noticeable difference from your onboard sound . Check out the guide to amps and dacs in the sidebar for more information .
