A normal USB port supplies 500mA, so when you're plugging your USB amp in such a "normal" port the Cube speakers (or some driver?) throttle the volume level (and thus power consumption). The speakers are just half as loud, but they work. On a Cube USB port they switch into specs-ignoring-hi-power mode and suck more than 800mA. I know for sure, I measured it ;-)) Oh, and everyone with a 7457 upgrade, please put your Cube to sleep as often as possible, let it sleep as long as possible etc., since a faster, but comatose Cube would be... a bummer ;-) I always put it to sleep when I go to bed (this is my work machine) and thus a flaky sleep mode would be really bad for me. I actually still wait for the dual board with the on-board VRM, this looks like a *really* fine piece of engineering ;-) Steffen -- Steffen Barabasch (mailto:TheMirror at westend.com)
