Let the upsampling - remonetization begin!!!
Very rare to source undithered 192/24 files.
Ear training schools will be needed.
12 mb mp3 to a 280 mb 192/24 bit files sound the same to most untrained ears. Heck some pay top dollar for vinyl cut from poorly dithered 44.1/16 bit files. One never knows the true source file unless it comes off the console - and most studios multitrack at 48k with poor summing. Sorry to crash the party - just speaking from the other side of the glass.
Wellllllll.....I am a early Roon adopter with a lifetime purchase..I have HiRez Tidal, I use iTunes for ALAC and I installed Amazon Music last night.  I’ve been using it for a few hours now....My initial impressions are very good.   Selection-excellent, sound quality-excellent (I signed up for UHD), navigation-interface much better than Roon and Tidal.  I don’t like Amazon (the business model) but I gotta say I like this.  Now, I also like Tidal for MQA so I’m not going to doing anything drastic yet...But I’m beginning to have dark thoughts that I could live with one service and Amazon may be it for me....say it ain’t so...RIGHT?
