I use an Air. Consider investing in a software program that will sound better than iTunes. I use dbpoweramp for ripping, and Audirvana Plus for playback. Otherwise you are good to go
Using Macbook Air as audio source
I would appreciate advice for a budget Audiophile. Plan on using my Macbook Air, 4 Gb RAM with external hard drives, iTunes, Bit Perfect) as a dedicated source for digital audio. Exposure 2010S, Def Tech Mythos speakers, small Apt space. Considering a used Ayre QB-9 DSD as a DAC. I realize the Macbook Air or any laptop isn't the OMG Wow, best source and would appreciate advice.
