I will ammend my comments. There are some truly bad recordings that are simply unlistenable. However, I find those recordings unlistenable on any system, if they're truly bad they even sound bad on my car system and the boom box at work.
I listen quite contendly to the vast majority of 6500+ cds and 2500+ lps in my collection. For me, and as Almarg stated, its more about finding some sonic aspect of the recording I like, my attention is more easily focused on the good qualities with higher resolution (the good qualities are made better).
I believe there is a lack of consensus about what recordings are bad, objectivity is hard to find here. I also put on different ears for different recordings, the music lover takes precedent over the audiophile for lesser recordings.
Again, I can only go by my experience, all my listenable recordings are more satisfying with each increase in resolution.
