For those of you coming from a Mac Mini to an Aries, what do you see as improvements both in UI and sound quality (if any)? I am currently using a battery powered Mac Mini (using PI Audio Battery Buss), I am running the latest version of Audirvana+. I have the USB output from the Mini going to an Auralic Vega DAC via a TotalDac USB cable, my Flac and DSD files are stored on a external Oyen HDD connected via Firewire. I love the sound and haven't been able to find anything better, however the UI leaves a bit to be desired.
Thanks,
Ed
