ishkabibil, I use a 2011 Mac Mini with a Wire World Platinum USB cable connected to an ISO Regen with linear power supply, connected to my Ayre DAC. I also run the Audirvana Plus transport app.
I think it's important to note that I installed a Synergistic Energy Blue Fuse in my Ayre. And, I have an XLR Akiko Audio Tuning Stick in the Ayre and a USB Akiko Audio Stick in the Mac Mini.
These tweaks most notably eliminated color in the sound; rendering the sound with neutrality, breath/naturalness and faster transients. The ISO Regen added clarity and detail to the sound. I am very satisfied with the overall sound of my DAC.
