@lewm I think you may have it upside down. Leaving aside damaged LPs (including groove damage from mistracking that may only be evident on playing) my experience is that it is the LPs you’d given up on as “harsh”, “boring” or just plain bad that benefit the most from a tip top LP playing system. Often as your system gets more resolving the hifi show discs suddenly start sounding artificial and messed with and it’s old mono LPs, great classical, 50s jazz, or in my case 60s folk, that shows its true colors especially after a run throughout your ultrasonic cleaner
so if your new LP system doesn’t make you want to spend hours with discs you’d previously written off as unplayable I’d argue it’s not really that good
