Yeah, I can't really hear the difference either, especially through my Equators, which are my primary source of listening these days (best $300 I ever spent). That said, I still prefer knowing it's lossless over Spotify Premium, it's just a psychology thing to me -- if I think it's better, then it's better, innit? I kind of wish I could convince myself that "bits is bits", but I suspect whenever I finally get around to putting together any of my better systems (Gallo 3.1 or Dynaudio Special Twenty Fives or JMLab (Focal) whatevers I have), I will be able to hear the difference.
But yeah, by all means, go with your own findings, they are the only ones that matter!
