FM can sound great with a great, fully aligned tuner if you have a station that broadcasts a great signal. Though with Tidal the sound is awesome too and you control content. Haven't compared directly, but I have a great Don Scott modified McIntosh tuner and barely use it since I got Tidal.
FM broadcast vs. streaming
What are advantages/disadvantages of FM over-the-air with a good receiver vs. the same content picked up via streaming audio? I know FM broadcast cuts off at 15kHZ and I figure streaming has compression. What's the bottom line on the sound of the one vs. the other?
