I am using Auralic Femto from 2 years. Great streamer with external linear PSU. They just redesigned the Lightening DS app past week and it is super fast now. But before you invest in streamer... buy good USB cable like Tellurium Diamond. I found it has one of the greatest impacts to streamer or PC application. I switched from 100$ Wireworld (Red) and it was WOW, the exclamation was never so obvious in case of streamer upgrade. Then invest in DAC. Having both look for better streamer. But focus on usage comfort rather than quality improvement. This technology is still under development.
