I'm late chiming in due to travels.
Still have the TP 2.0n (Amperex PQ White Labels), and still lovin' it.
Victor - I did something a bit different for downloaded music. I've ripped my collection to Apple Lossless, stored on an external disk hanging off an Airport Base Station wireless router. I hook my MacBook Pro via USB to a HagUSB device, then feed that into the digital input on my Resolution Audio Opus 21 CDP, utilizing the DAC internal to the Opus. It works well and is easy to set up any time I want to use it. Perhaps not the greatest fidelity, but "Party Shuffle" makes up for it when I'm out on the deck.
