Best sounding LP's

I've been collecting LPs for about 40 years and definitely find differences among them. It's not ALWAYS related to label, but in general I've found European labels to have a higher quiality. I'm particulary fond of Philips. On the other hand, two of my all-time favorite LPs are from an American company with a tiny catgalog - Reference Recordings. They make some of the best recordings on Earth.

From my experience with my collection(I own ~7k classical LPs but have not listened to them all), I like below labels(I really don't care for some of the newer audiophile re-issue lps):

-Most of RCA Living Stereo labels(ones with shaded dogs). Slightly in warm side. Dynagroove versions very unpredictable. I like most of LM(mono) shaded dogs as well.
-Mecury Living Presence(if your analog front end can handle the hot pressing LPs) both stereo and mono.
-Philips(holland pressings), US pressing Philips does not sound as good.
-CBS Mastersound issues, excellent performance and sound.(I love those YoYoMa albums)
-London/Decca/Lyrata/Erato, some sounds little bright
-Denon, great quality, somewhat less dynamic than the others maybe due to PCM recording.
-DGG, some very excellent, some so so(ones pressed in Germany usually sounds good). Blue tulip label ones are excellent.
-EMI Angel, not Angel. EMI Angel LPs sound good but US pressed Angel label sounds dull.....
-Telarc/Teldec/FSM, sounds very similar to Denon.
-MHS, mostly excellent pressing/performance.
-I have some USSR pressed Melodia(spelling?) label LPs which sounds great.

Well, fortunate thing is that there are loads of used classical LPs still available and prices are excellent. I won't pass above labels if price is around $1-$2.
Condition wise, it is very hard to find NM condition RCA Living Stereo or Mecury Living Presence. DGG/MHS/Philips LPs I usually see are in NM condition(maybe due to polylinded inner sleeves in these labels).

Matt8268,

Some of those heavier vinyl discs are not necessarily "audiophile" 180 or 200g LPs. If they are older, they are probably 150g.

You can't go wrong with any of the Decca classical reissues on Speakers Corner. They are pricey at around $25 each but you get a thick slab of 180g vinyl for your money. Next up would be the Classic Records reissues some of which are being sold for $10-12 by web sites such as www.amusicdirect.com and www.elusivedisc.com. The Classics jazz reissues are pretty good too. On the pop side, you have the usual suspects (Pink Floyd "Dark Side" and "The Wall", Neil Young "Harvest", etc.). Check out Ebay and you can pick up some of these for less than $5. Good luck.
