What is a good intro to "Mahler"?

Thanks for the advice, unfortunately prior to reading this, I found a copy of Mahler's 5th from super analogue and purchased it. I was so happy to find a new copy that I didn't hesitate. Hopefully it wont be too bad. Of the Mahler recordings that are currently available on vinyl, which 2 or 3 would be the best bets?

Thanks,

From used specialist dealers you can probably find:
Mahler 3 Horenstein Unicorn pressing. Not Nonesuch.
Mahler 2 Klemperer EMI pressing NOT Angel.

I'm looking for the LP Mahler #3 Horenstein....difficult to find (so far)!

Ethannnn, try also to get the Klemperer Mahler 4, available currently from the mail order dealers as one of the EMI reissues (Testament?). And hey, if your speakers don't go too far below 50hz, maybe the Cisco will be listenable?

Thanks for the tip, I am new to classical and vinyl so I expected making some mistakes. Can you recommend a good recording of Beethoven's Egmont Overture? I have a copy from Classic records but felt the pace was too slow. I'm looking for pieces that are grand and engaging, ideally with moments of delicacy. The ONLY 2 classical records I own are Beethoven's Egmont Overture and the pending Mahler 5th Symphony. Any recommendations on recordings currently availble on LP that I should try?

Thanks,

By the way, I do have full range speakers with full tube equipment so I'm curious to hear what the Cisco recording will sound like. :)
