Waiting patiently on the USB output update..I bought a Node yesterday from Richer Sounds (UK retailer of audio/visual electronics). It was one of only two on clearance and I'm listening to it right now (via my RME ADI2 DAC) and couldn't be happier. I couldn't get RME's ASIO driver to work without (very frustrating!) dropouts, no matter how many processes I stopped etc. This works flawlessly and I love the BluOS app (although I still haven't worked out quite how to do everything I want to do).
Have 2 earlier generations and would like the USB output option but not investing on a promise
