How are you going to get a signal to the amp? If it doesn't have Bluetooth, you are going to have to plug something into it.
Edit - oh, you mean from your laptop to the amp rather than you don't want any cable going to the amp. You can buy things to provide a Bluetooth connection to the amp.
That's essentially what I'm looking for. Currently using a basic bluetooth unit, but I was wondering if there was something bigger that would accept a USB hdd as well as being some sort of wireless unit that I can connect to the amp/
