Topic: about ADI-2 DAC possible problem with Mac os USB defult-driver
My new ADI-2 DAC USB Connect to Mac os on defult-driver , I found that high frequency is less than before audio system.
play pink_noise to check the full frequency.
1.ADI-2 DAC USB Connect to Mac os with defult-drive
2.Play Pink noise , and found Level attenuation from 16Khz on the ADI-2 DAC screen
3.ADI-2 DAC Line out to PC ,and run Smaart（Audio frequency software） to double check，and it also exist : Level attenuation start
4.ADI-2 DAC USB Connect to Windows (with MADIface driver ), Play Pink noise ,found No Level attenuation, is very OK
5.ADI-2 DAC select another Audio player （ VOX iTunes ）on Mac os is also Level attenuation at high frequency
6.another DAC SONY PHA3 Connect to Mac os with defult-driver （ Audio player （ VOX iTunes ）） check is OK
I think there will be some compatibility issues with the default-driver on Mac os ？
and Is there any other driver to choose except default-driver on Mac os?
My ADI-2 DAC hardware 25 (update new verson) SN:57750XXX ; Mac os 10.14.4
