How many LP's

What technology is best? I vote for air bearing, although a prominent and expert guru (Ralph K) disagrees. Even so, I'll bet he'd like my system.

I use a DIY air bearing TT with a Trans-Fi air bearing arm, playing a Koetsu platinum cartridge. The air bearing TT replaces a Nottingham Analogue unit, which has been updated, and is essentially a Dais. Which I recommend. But not as highly as the Trans-Fi arm, which is $1000 and plays with the best.

Lewm, you make a good point. For every one of those 100 jewels there are many also-rans.

As for which ones? Other than the usual workhorses, La Spagna (BIS); Scottish Lute Music (BIS); Laudate (Proprius); Cantate Domino (Proprius); Wagner's Ring Cycle (Solti - the best is on Telefunken);   Hearing Solar Winds by Hykes (Ocora); Gorecki Symphonie #3, with Stefania Woytowicz (Erato - sound track to the movie Police); Salve Feste Dies (Phillips); Beethoven's Emperor by Gieseking (Varese - stereo - repeat stereo - recording from WW2 Berlin - you can hear the anti-aircraft cannon at one point - and you hear the Emperor as you've not heard it before).

Last night I picked out of my Duke Ellington collection a Pablo LP, "Duke's Big 4", or something like that.  Turns out I have two copies of this LP, and one is an original German pressing.  Needless to say, that's the one that got spun. Duke + Ray Brown + Joe Pass + Louis Bellson.  Wow!!!!  Was not in regular rotation.  Great fun. Pablo's with the blue/white label are fantastic.

This put me in the mood for more jazz piano, so I got out Oscar Peterson in a quartet, also with Ray Brown on bass.  Another wonderful experience from my not regular LPs.

I'm more of a quality over quantity guy. I got back into vinyl about 7 years ago. I'm 55. I had vinyl, 8 track, cassette, cd, said, DVD-A, downloads in multiple configurations and now back to vinyl. I don't know how many albums I have now but it's over 700. If I can get a 45rpm version of the album I will always get that one. I stay away from the bargain bins. I like to get a new copy off the master tapes if that's available. I don't have a problem buying a used album from a collector either on Discogs or my local record store. One of them buys collections and separates the really good stuff. I live in New Orleans and there are 4 record stores walking distance from my house and another 2 within 3-4 miles. So I'm fortunate. I haven't figured a good way to catalogue them without actually going through them. I listen to everything I have, obviously some more than others. But I have no problem pulling something out blindly. I used to have a large wine collection. There were wines I wouldn't drink unless it was a special occasion. Then I got into a motorcycle accident. Everyday became a special occasion. If somebody was over I would blindly pull from the cellar and pull the cork. It's the same with my vinyl collection now. If I bought it, I must've of liked it so why not listen to it. If I want to listen to something I'll go for it but sometimes I just randomly pull. That's why I have more than a few albums.
