iPod docking station - Belkin vs Wadia vs Arcam
Lazy and looking for an affordable (i.e. cheap) iPod docking station to play music thru my audiophile system. Don't want to have to invest in a DAC. Understand that the Wadia unit requires a DAC. I'm aware of units sold by Arcam ($300) and Belkin ($100). No remote with the Arcam. Anyone have any experience with these units?
