Hello all,

I just bought a DAC Magic 100 to connect to my iMac. When connected
via USB it indicates a 96kHz sample rate at all times, whether
playing or not - including when playing 44.1kHz material. Presumably
the Mac is upconverting. Is there any way to stop this?

Try Audio Midi Setup. It should be found in your Utilities folder.
