If you’re using windows and locally stored files (ie not Spotify) and don’t mind using something like Foobar2000 or JRiver. Then some amp/dac combos will sound better. Don’t expect to be blown away by the difference though.

If you’re streaming music and movies a dac/amp combo should give you some appreciable improvement, but the difference is even less so.

I tried my onboard sound card compared to a sound blaster zxr card on my Audiotechnica Ath-MSR7 ( I think). The sound blaster was noticeably better, but $200 better…that’s up for debate.
