I am looking to buy a system and would welcome advice - I have in the order of 3000 CDs either ripped to hard drive or via iTunes. I am moving onto a narrowboat and need a music system which will allow me to access the stored music, but that also has DAB radio availability. I would also like to use Bluetooth speakers so I don't need to cut out any more of the walls. It needs to be reasonably sized as I don't have a lot of space and it will need to draw a small current as when I'm cruising it will work off an inverter- does it exist???
