Thanks Enrico. I was just sending it out by setting my output to 96khz/24bit via toslink in audio MIDI setup. Setting it to exclusive (as you have shown) and looking at the audio input on my receiver; exclusive mode does in fact change the output from my iMac based on the media being listened to. The Beach House album I was listening to was at 88.2khz, then I switched to M83 Junk and that is showing 96Khz.
