Can someone help me please. Earlier this year I brought a superb Denon D-M37DAB stereo which I am very very pleased with and would highly recommend. Do I need to purchase a docking system to use my ipod touch (2nd gen) or can I plug it in using USB on front of system. If I need a docking system anyone got any suggestions as to which one is worth a punt. I'm sorry but I recently posted same question thinking system was a 38, I'm such a knob.
