I route everything through my pc into my amplifier via a m-audio soundcard. I don't listen to radio very often, but I prefer the quality of my amp and speakers. I don't use standard pc soundcards, the m-audio 2496 has two phono connectors, that plugs into my Technics amp and also my Hercules mp3 DJ mixer, two Ruark speakers for a quality sound. I do my own DJ mixes on my pc and have also used software on my pc to produce my own dance music, so quality reproductive is needed.
I'm not sure if this helps you or not.
