Dragonfly DAC

Am considering buying a Dragonfly DAC (black or red I'm not yet entirely sure). I've looked thru' other forums and Audioquest's own site but haven't seen a definitive answer to my question.

I'm gonna be connecting the DAC to my Onkyo TX-NR414 amp which I use for pure audio and home cinema. Will the DAC play & transmit anything from the computer ?? I.e. radio stations via MusicBee, AIMP etc. and audio playing on specific websites i.e. YouTube and UK specific radio station websites.

I ask this because a lot of reviews mention, Spotify, Pandora but don't say just 'everything'.

I have a desktop PC but the soundcard won't work on Windows 10. (Windows 7 is fine). I thought this might be a good solution for both Windows 7 & 10.

Thanks in anticipation.
