Looking for some advice here. As the only member of a community group with any technical knowledge I have been appointed as unofficial station engineer for a small non profit radio station. They have all their music stored in wav format on an external hard drive on an XP computer. The pc has an M-Audio 2496 sound card and the audio output is fed from the rca outputs directly into their audio processor. I feel that an external DAC could improve on this. Any recommendations for a DAC?. Bearing in mind that the sound is for FM broadcast would the limitations of the medium wipe out any gains made by using a DAC? All suggestions welcome
