We express our own opinions, just like you. Personally, I try not to make sweeping generalizations about SQ of any medium like disc, vinyl, or FLAC. There's a huge range of bad- and great-quality recordings out there, in all formats. So I challenge anyone to pigeon-hole any single medium as the best for SQ across the board.
When I buy a CD I really acquire TWO collections that I own, permanently. 1. The CD itself i.e. the original media/recording, with its liner notes. 2. The digital file collection, in FLAC, which I create when I rip the CD. With #2, I can, if I wish to, modify the music with available software, through editing, mixing, or EQing (the latter is verboten for me). If I screw up with the massaging of #2, or if I lose all/part of #2 because of hard drive failure, I still have the original CDs. A big plus, imo. I don't need to obsess about continually backing up a massive file collection on separate drives.
Enough said on this. We all like certain media, that's clear.
Getting back to the OP topic....best HP for CM?
