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.

I use a MacBook Air with Audirvana Plus and could not be happier with the result. See my previous post on this system:

If you have access to the British magazine HiFi News, there is an article about the above system in the April edition.
@mgattmch - no pics here of your system? I remember the Gale speaker.
Something about second systems using vintage that don't cost both arms and a leg that are special. I have had the same experience, using old Quads and an assemblage of equipment most of which I had for decades, restored. It's musical and doesn't demand anything other than that the listener enjoy. 
whart - If I knew how to post pictures in the discussion section I would. Is there someway to do this?

you can set up a virtual system, Marcus, so that when somebody clicks on your name, it offers a link to that. It will allow you to load a bunch of photos. Click on my name as an example of what I’m referring to; there is probably an FAQ here on how to do it.
In terms of posting photos within a discussion thread, there is a link button but I simply use the tried and true: [url]XXXXX[/url]  
Obviously, the photos have to be hosted somewhere, but there are plenty of sites that do that for free.
