As a manufacturer, the transport and DAC still sound better than any streaming device we have tested. It is close though and getting closer. What we found for better sound quality is the equipment. I can modify a transport (CDP) and DAC, but we have not ventured into a streamer at this time. Upgrading the power supply in many components really helps the sound quality from our experience. The benefit of having a streamer with all your recorded music is a big convenience though.
Happy Listening.
