@sns I will put my bet on digital file serving (on a local high-performance music server) to be the de facto standard for high resolution / high fidelity playback. Even though streaming using high quality Ethernet/optical and quality switches/reclockers get very close, the shortest path will always likely win.
I do have faith. In the last year I reached a reference grade with my digital setup, using the Aurender N30SA server/streamer going into the T+A SDV 3100 HV DAC preamp. Using the Synergistic Research Ethernet Switch UEF and DH Labs Reunion Ethernet cables improved the quality of streaming to get it close to the local files stored on the Aurender, but local files still win. Both are generally equal if not most times better than my vinyl rig, which at about a $60K MSRP is no slouch either. But digital will just continue to get better, and I can’t say the same for vinyl. But who knows what the future holds?
