Hi Everyone, First I want to apologize for my post, I'm sure this has been answered once or twice before. But I am having no luck finding a clear answer. I am a new Apple owner and have a iMac and Macbook Pro. When I came from my windows based machine I had all my music stored on the local machine and then synced through iTunes. What I am looking to do now is store the music on a dedicated system (NAS preferred, since I have one available) and then stream the entire library to the other macs with out lag. When I attempted to do this on my Windows base machine I ran into a very large lag when playing the files from the NAS to iTunes. Having the ability to have one mac shut off, yet still be able to play music on the other is the key to making this run correctly, as well as through a airport device. It seems that everything the Timecapsule offers will correct the lag issue and even give me more features than the NAS. Can someone direct me or instruct me on the best way to get this to work? All the macs are on wifi.
