Not providence, that's a city in Rhode Island and a failed tv show.
However, provenance is the key to the original question and many broad brush posts above are just plain wrong. You can't conclude anything about Hirez overall from listening to an HD Tracks demo. Sure those will sound good. Almost anything from Blue Coast will sound great. Not enough of what's for sale for $25 sounds great and shame on those selling upsampled redbook and calling it Hirez.
HD Tracks and all others need to follow far higher standards of disclosure so the public knows what they are paying for. It's true that with many better DACs (especially R2R DACs and some others) and today's better servers and other digital sources redbook(i.e. CD) quality files can sound better than most associate with playing CD disks, and this quality regularly surpasses what is heard on some poorly produced hirez.
It just ain't fair! We need somebody with real musical cred like Neil Young fighting the good fight! Oh wait, that didn't work so well. Cheers,
