...proof advice. SEE MORE...? need to set up a music system and need advice on adding something that will enable us to play the ipod and maybe music from the laptop through the same system. Have a Cambridge Audio A1 Integrated Audio; a Cambridge Audio DAB 300 and two Gemini PT 2100 decks to join together so far. Do we need a mixer, and if so what sort to enable all of the above?!? And at a decent price. Or is there another way?
