Okay, so I have a main system that I play all LPs on.  I've got that covered.  I also have a fair collection of Apple Lossless formatted cds on my Macbook Pro.  I want to be able to enjoy these in my office.  I am planning on getting the new Audioengine A5+ as I have always been impressed by their products.  Does anyone have any recommendations on a good, affordable DAC.  I don't feel like spending too much money on it, around $200...hopefully less.  I would appreciate any help.  Thanks!
