Excellent sounding LPs

Being I've spent the majority of my time seeking out the best versions for most releases I'd say the majority of my LPs sound very good, but still I probably have 10-15% that are merely OK. 

Working my way through a lot of inherited classical LPs, I have been impressed with the budget Nonesuch label. I don't have any of their modern releases, but I haven't fond a bad one yet from the 60's and 70's.

I guess it depends on how you define "audiophile."  I'm inclined to define it as meaning the ambience of the recording venue is well-preserved, so that would eliminate most rock recordings, since they are generally close-miked and generally speaking only live recordings have mics for picking up the ambient sounds.

So using that definition, I'd make a rough guess that half of my moderate collection (less than 1000 LPs) are close to audiophile--mostly classical recordings and some jazz and ambient/new age recordings.  Interestingly, many ambient/space music recordings have false ambience added (through artificial reverb) that conveys the illusion of a two-dimensional soundstage.  I'm not sure whether those should count as audiophile, but many sound as realistic as a mix of acoustic and electronic instruments can sound.

Simplified by percentage, a 20-60-20 Bell Curve (great-average-poor) with audiophile quality being in the first group.

It seems to me that you may need to understand what @fa8362 in particular, but others in this thread so far have said as well.  Do you have cartridge choices?  Do you have a couple of different TTs?  If you play mono records, you need to at least have a mono switch on your preamp, but better is a mono cartridge.  Do you know about the Sugar Cube, which is a digital filter that can dramatically reduce noise caused by scratches and such?  There are a lot of things you can do to make a pigs ear into a silk purse when it comes to playing records.  A good record cleaning machine is a good first step.  It is not just seeking perfect records, frankly there are not very many of those anyway.  Far more effective is to learn how to deal with what you've got.
