I just purchased Beyerdynamic D770 Pro 250 ohms, and I have the http://www.newegg.com/Product/Product.aspx?Item=N82E16829121120 Soundcard in my PC, but I'm using a crappy 15
year old Sony Receiver to power my speakers atm, I want to get a nice desktop headphone amp to run straight from my soundcard through the RCA outputs into the amp and straight to
the headphones. I'll be using them for mostly music (heavy metal, dubestep, deep bass, etc), games, and movies.
Any help greatly appreciated,
