Thank you very much c I knew the song was old , but I haven ' t seen many memes until recently . While I think they ' re great , I think the market has had enough of them p <| sep |> If you remember back to the Iraq War protests you had communist groups like International ANSWER organizing the big protests . I attended a few of them but I truly cringed at some of their signschantspropaganda crap they were shoveling . No , I am not interested in your fucking workers revolution , I just want kids to stop getting killed for nothing in Iraq . I guess most people who are not radicals have lives and cannot devote the time necessary to organize these type of events . <| sep |> Just as a point of reference , the HD 650 HD 600 will sound great without an amp , but you ' ll get the most out of the headphones with a DAC amp . I use the Bifrost and Valhalla 2 because I got a great deal with the HD 600 . Most would probably say you don ' t need as an expensive DAC and a Magni 2 would be fine for an amp .
