Wrap-up: Given the current trend away from physical media and the lack of consensus as to how long manufacturers of transports/CDPs might continue to stock parts, I'm unwilling to gamble on spending 3-4K to upgrade in that direction. At the same time, I'm in no hurry to jump into computer audio. If I had unlimited funds to lavish on audio or harbored a fondness for frequently buying/selling gear, it might be a different story. As neither is the case, I can't see a way to go that's more practical than hanging on to what I've got until the Jolida gives up the ghost, and then, moving to a server... barring the unlikely event of a transport/CDP "renaissance", due to some sort of technical break-through we can't yet foresee. In the meantime, I offer my thanks to everyone who contributed to this thread.
