Spotify out of my I-pad air using an Apple photo USB interface out of the I-pads lightening connector to a Dragonfly Red DAC plugged into the USB then into a Dynaco PAS-4 Tube preamp (Panor Corp version 1995) using Telefunken E88C tubes feeding twin Harman Kardon Citation II tube amps (1960) using EI KT 90 tubes, driving a pair of Martin Logan SL3 Electrostats. I select Spotifyies high resolution feed, which is better than CD quality. Spotify allows you to create up to 10,000 songs in your library. I’ve got 5 decades of collecting vinyl and a large collection of CD’s. I prefer the Spotify feed, outstanding separation, clarity, immediate response to selections (no waiting at all, its instant), and my digital library now eclipses my physical collection. Couldn’t be happier, they have everything I’ve every looked for.
