I like well recorded music. I have friends who could care less if it is mono or recorded on a cassette if it represents a period they like. For me, I find that difficult and enjoy good music and well recorded sound to bring out the best with the dap I am using. So while this is a portable source gear forum, I would like to know what you think is the music that brings out the best or worst of your portable source gear. One of my favorites is Neil Young's, 92 live album. It gives me the hall sound of a live recording and the realism I like but it requires that the dap be able to deliver this and the better the source gear, the better this album gets, IMO. I also enjoy a few cuts of Michael Jackson's "Thriller" album. There are others but those are two I enjoy. And hi resolution or cd rips?
