"With these CDs the revealing player sounds biting, harsh and "lets through everything."
From my recent experience, if this happens regularly with many recordings, there is a good chance it is noise and distortion sneaking into your system somewhere upstream that is the problem, not each individual CD. Are you using any power conditioning? I've found both power conditioners and power cords like Pangea 14 series to be effective as designed to reduce noise and distortion that contributes to a subtle edge in the music. Those are good investments that need not cost a lot. Try that first maybe before changing anything else.
