What do I look for in used records?


I've been absent from vinyl for years. Actually, unless I resort to my 25 year old Pioneer SX-850 and Technics SL-1400, I'm still absent. But after reading some of the posts here, I dropped in the local Goodwill to see what might be found, and picked up a 1955 copy of Brahms Violin Concerto - Heifetz/Reiner RCA Victor Red Seal LM-1903.

I'll admit, I don't really know what I'm getting with this. I'm not even sure this is stereo, since the label just states: A "New Orthophonic" High Fidelity Recording.

Is this good? There were several others that I could have also grabbed, but thought I'd ask here what to look for before proceeding. thanks

I'll buy anything I see on Everest and Nonesuch

I love the Nonesuch stuff - kind of an "artsy" label, often with recordings of, uh, less-widely sold music - Japanese zither, Scott Joplins' Rags, "The Play of Herod," "Swedish Court Music of the 16th Century," you get the idea - and are usually (in my experience) very well-recorded and packaged, and the vinyl is usually pretty nice

Everest also had similar marketing strategies, and also produced high-quality LPs - the covers (like contemporary Deccas) are often bizarre/cool/retro-cool - take your pick
