I am not computer literate and will be switching from an iMac to a MacPro... I have two Pono apps on the iMac. Should I uninstall either? Both? If I install them how will I play the HD music on my stereo? (I do it now through Pono but hope to connect it via DAC). How will I add new music to the Pono? Should I use just JRiver instead? What about a software such as Audirvana? This is way more confusing than I ever wanted but the sound is great so I'm persisting. Thanks in advance, A.
