As to performances, there are LPs and CDs which do not duplicate them or have equally good mastering/sound. My Marston CDs of vocalists and pianists are not available on LP and often extremely rare originals (78s, Pathes, Edisons, etc). They sound wonderful on high end equipment. They don't necessarily need the analog equivalent to extract the best sound possible.
As to high end sound, I have many LPs and CDs, where both were good remasterings, yet the LP is slightly better than the CD. Then again, I have so many mediocre LPs due to inferior mastering or pressing where the CD kills the LP. Until I purchased my EAR Acute CD player, I didn't enjoy CDs. Now CDs are on an equally enjoyable footing as my analog gear. I wouldn't want to live without both.
