I just got my Groove and I have to say the sound is great! One question though - I'm running this on Windows 10 using the latest 3.0 drivers from Apogee's website. I installed the drivers and plugged in my Groove and that was it. Everything was left at default. Is this all I need for it to be capable to play back 24-bit/192kHz files or do I need to fiddle with something in the settings? I was hoping the LED would light a different color when playing hi-res files so I know it's working but it's still lighting green.
That reminds me - I need to try out some DACs since my laptop "upgraded" itself to Windows10. Previously, I would recommend any user under Windows 7 use Foobar2000. It's a great interface to be sure you're spitting out the bits cleanly, and it gives you more details on exactly what audio you're feeding into your DAC. But I will need to go home and try this myself!
I'll let you know!
