I have a last generation Apple TV in my living room. Would like to invest in a set up that includes a DAC, a receiver and (bookshelf) speakers to listen to streamed lossless files from my main mac. Not interested in surround sound or anything like that. I would also like to hook up my current Bluray player to the receiver to play actual cd's. I have a very low budget, $500-800 and am curious to hear how (and on what brands/ models) I should spend the money. Have a read a lot of positive reviews about the Audioengine D1 DAC, but am in the dark re receiver/ amp and speaker choices (heard good things about Polk). Any advice is greatly appreciated.
