Confused about fields and which driver

Does anybody know what the 32/44,1 figure is in the bottom right corner? Why is it different to the 16/44,1 k. The bottom left?

Also I changed from WASAPI to ASIO and that figure went from 24 to 32 and audionirvana now sees my dac as dsd compatible.

Sound quality seems better which I am obviously happy about but it is frustrating not knowing why (I thought ASIO and WASAPI were both bit perfect?)

Hello @Yossarian, the bottom right corner indicates the capability of your DAC. The bottom left is for the file format of the file you are currently playing.

Finally if you do have a ASIO, this is the only way you can get DSD since WASAPI son’t support this file format.
