I completed the frimware update on my AresII about a week ago. Used a PC with Windows 10. Made it through.
Have an Audioquest NZ-3 power cord and a PS Audio power regenerator serving the DAC.
DAC is set to NOS and Slow filter. Change is all positive. Everything from bass to treble is, my best description, more distinct and locked in. Just better and more fun.
Also the occasional click when new tracts cycled up on the Pure Vinyl running Macbook are now absent.
