I have an Apogee Duet 2 which is wonderful in many ways, except for a completely unacceptably loud 'thump' whenever the computer is started up or comes out of sleep. Apparently USB switching power on sleep is a recent energy saving feature in the latest OSX ML. Obviously I could turn my speakers off before powering up, but as my iMac goes in and out sleep 10 to 20 times a day, this isn't really practical. As a note, this was never a problem on the Firewire powered Duet 1.

Apogee engineers have been saying for most of a year that they know about and are working on the problem. But I am so fed up that I am switching to an alternative - so, considering the RME Babyface. My question is: can you RME users reassure me that the Babyface doesn't have exactly the same problem on USB? The grass is always greener, but I can see from the forum that the Babyface isn't entirely without its problems (though also with many satisfied users as well.)

Any guidance would be most helpful

Thanks.
