Windows Topping D90 and Tidal... and Audirvana?

So… Topping D90 Windows 10 (NUC maybe a year) and mostly Tidal (some flac on a NAS too). Good speakers and amplifier so I hope that my ears can hear that it will be better…
How to get the best sound from this… I don´t understand this thing with ASIO and the other two?
Oversampling x2 and other numbers…
Could you please help me with the right numbers and how to make it be the best possible sound for me.

Best Regards S
