I have one and have been testing it against the PS audio stream DAC which is almost twice as expensive. I’m very happy with the sound. There is definitely a warmth, brightness and detail that makes it much more pleasing to listen to than the PS Stream (which is cold and clinical by comparison). I hear more detail with the Prima Luna as well. It is a big improvement over the DACs I had before (built ins from my Marantz SACD player and Node is). The Prima Luna is very quiet background, beautiful detailed mods highs and bass. Sound stage not as wide as the Stream but so far no comparison as to which I enjoy listening to (the Prima Luna). One thing that surprised me is a red book Beatles mono CD - it’s always sounded dry and sterile through other DACs but sounds beautiful detailed and warm on the Prima Luna.
