PS -depending on what I do with the main system music server (and I might not do anything - waiting for the dealer to lend me an Aurender N100H to try), I might consider the Gustard as well (I look at the thread from time to time but have not focused on it yet) for my back-up system (and move my Teac UD-501 to another since I'd have an extra music server if I upgrade the main system).
