I'm, as a pensioner, not in the league of you experts on here but am trying to understand the best means to listen to my cheap system. I store my music on an ipod which is MP3 format I believe. I have a device which connects at the ipod charger connection end (Not earphone connection) and goes to RCA ? At the other end (red and white connections) I have an amplifier to connect to from there. My question is: Do I need a DAC and if so where would it fit in to my simple 'Circuit' Which would connect to which and which DAC recommended (Would the Cambridge Audio suit) ? In simple terms please. Am simply trying to get the best from a poor basis. Thanks.
