I have M-audio audiophile 192 soundcard and a Technics rp-dh1200 headphone. I am getting output to headphones from monitor out of the sound card. As headphone has only one socket I only use one input of the monitor outs. I want to buy a headphone amp to use both of the inputs but my question is that my headphones do support any headphone amps? I am scared of burning my headphones. Also if the answer is yes, can you give me some headphone amp models please?
