Great suggestions on the hardware. Thanks!
I started out using Apple Music because I've been using earlier iterations of Apple Music for years. Then, the NAD dealer rep showed up to set up my system. He began to praise how Tidal provided much better quality audio. So, now I've been testing out both services. In the mean time I've been hearing about how Apple is working to improve its sound file quality. So, now I'm not sure which of them to pursue. Please let me know if you have any suggestions regarding a preferred service - Apple or Tidal - and if either has better features? Thanks!
