So I Just replaced my 2007 Mac min with a new 2012 Mac mini with 250Gb SSD. I would have to say I'm neither really proficient with computers nor a serious audiophile. I love the convenience of a music server as I stream to two other receivers in the house. I have always wanted to get some better sound out of the server in my main listening area so here I am in search of better sound. I have read many posts and find myself a little out of my league with the computer lingo. I was hoping to get some help setting up my Mac so I can get the best sound I can out of it. I have it hooked up with HDMI to the Dennon AVR 4306 and USB to a Cambridge Audio Dac Magic. I think the music is only streaming through the HDMI. How do I set it up to go to the Dac And what other settings should be changed on the computer and in ITunes. I was going to try out Audirvana will the setup be different with that. All my files are AIFF on an external hard drive that is also USB. That drive is almost full, and I'm looking for a recommendation for a new drive,i was thinking of the G-Technology G-RAID with Thunderbolt. Does anybody use one of these? Also going to change the USB to the Audioquest Carbon , Any opinions on that?
