I recently purchased the Beyerdynamic DT-990 (250 ohm) and am wondering if I need an amp to power them through my PC. I currently am using the Asus Xonar Essence STX soundcard linked here: http://www.newegg.com/Product/Product.aspx?Item=N82E16829132010 . A friend of mine recommended something like this: http://www.mav-audio.com/base/product/tube_magic_a1 to power them.
My question is.. what benefit will I get besides volume increase (maybe?) by buying an additional amp. This sound card already has a built in amp and DAC if I'm not mistaken. I'm just not sure how good it is compared to stand alone amps on the market and/or DACs. I'd like some suggestions for amps at least. I never listen to these headphones outside of my house, so I don't need anything portable. I'll also be powering my AD700 and M50 headphones through this setup. My main use is gaming and I'm just dipping my toes into listening to high end audio stuff as it's available to me. thanks in advance!
