This document discusses hi-fi streaming services and whether they are worth paying more for compared to standard streaming services. It summarizes the views of an audio expert who argues that hi-fi streaming can restore the high quality of music that was lost with MP3s and compression. However, the document also describes an experiment that found most people could not distinguish between hi-fi and standard streaming services. Ultimately, the document concludes that hi-fi streaming is not necessarily worth paying more for given that many listeners cannot tell the difference in quality.
