I didn't have a close enough match on an external PSU at home, so I haven't tested this yet, but I did have success powering the unit from one of my PC's firewire ports. However, using this option there seems to be background interference coming through the speakers. Not a huge amount, but enough to notice considering how quite operation was with the PSU.
Can anyone answer the following questions:
1: Is powering the unit by firewire port going to result in any damage? The manual says you can do it but online research suggests it's not recommended.
2: Does anyone know what might cause such interference and, more importantly, how I might reduce or remove it? Could it be picking up the noise through the computer's firewire port, or might there be some other reason?
