iTunes - DAC / USB

[pelleas75]

Hi !

 

I just bought a Havana DAC by MHDT Labs. A Apple Laptop (Mac OS X) is connected in the DAC via USB and I play music with iTunes. I wonder whether there are some changes to do in the Audio Devices Setup of the computer (see website link hereafter) to get the cleanest, most unadulterated signal to Havana via USB ?

Thank you in advance for your time and consideration in that matter.

 

Best.
