I have a Mac mini 1.1 hooked up to my Sprout 100 using the usb input. I wanted to know if you have any suggestions on software needed to improve sound output from iTunes? I am running Snow Leopard OS 10.6.8 and iTunes 11.4. Bitperfect says they don’t support this setup anymore. Any tweaks I can use? The setup sounds great right now but it seems after watching a few of your Youtube videos on this subject you talk about the Mac messing with the pure digital recording.
