Best sounding cd's

I'm trying to get some idea of the CD's out there that are well recorded to enhance my listening. My system is very revealing and as many of you know the recording can make or break how it all sounds. My tastes vary across the spectrum and go from rock to folk to classical. I welcome your suggestions. Thanks. Dave. My top 3 recordings (mainstream) are

1) Barenaked Ladies - Gordon
2) Norah Jones - Come Away With Me
3) Sting - Ten Summoner's Tales
