@analogfan I’ve used Audirvana for years now, running on an old Mac Mini with an Uptone DC supply. It’s always sounded great. Part of the magic is the pre-loading and conversion of files to PCM. It recently updated itself to 3.0 and everything went awry, but after a few discussions at the forum the problems were fixed. However, I still prefer the sound of 2.11, which a forum member kindly sent me to restore. It just sounds more solid and realistic to me.
