Buyer beware, there are a lot of DSD offerings today that are nothing more than the original (non-high resolution) album converted to DSD format. I learned this the hard way years ago after having bought several DSD downloads.
There are just a few recording labels that do record in DSD format, but the number of true DSD recordings remains limited.
Using computer software (HQPlayer, for example) a person can take ANY non- high resolution file and convert it on-the-fly to DSD format for listening.
