I definitely plan on investing in one of Schiit's tube amps eventually!! Tubes have always fascinated me but I decided to start off simple because of the fact that I only have mid-range headphones at the moment that I don't entirely think would benefit from tubes, haha, although knowing how good the SHP9500s are, I wouldn't be surprised if they would actually benefit from them.
Also unrelated but it seems my iPhone gives more volume and punch when connected to my Schiit stack compared to my PC running Windows. I don't know if its just the way Windows handles its audio stack, or what, but I think iOS's (and in turn macOS's) audio stack is better than the audio stack built into Windows. Really interesting.
Might invest in a Mac mini or something and move to Apple Music full time because to me Apple Music sounds the best compared to TIDAL and especially Spotify. We don't have Qobuz or anything here so Apple Music / TIDAL / Deezer are our only options, and Deezer isn't very good, sadly.
I obviously left out Spotify because it
still lacks support for lossless / Hi-Fi audio, even despite the fact that Spotify announced several years ago that it was coming.
