Where do you look for rare records and pressings ?


Reliable sources, people that got or can get real things. Not ebay, discog, craig moerer, garbage bins, goodwill, yard sales,thrift shops etc.
Miles Davis, Mahavishnu Orchestra, Dead Can Dance, El Camaron/Paco de Lucia etc -  pro and test pressings, including first release Japanese. Couple of Pink Floyd and Deep Purple maybe.
I have a few, they sound vastly superior. Best way to improve the sound.

Aside from select Estate Sales , we have Vintage Vinyl and recently, CD Warehouse here in St Lou that have hidden gems if you want to put in the time or days to browse.  I have been lucky on finding some Japanese JVC Direct to Discs, EMI Toshiba Pro-Use DD, and some extremely well made GRP Digital Masters.  Stumbled upon a very rare Ray Manzarek sealed copy of the "The Golden Scarab"  last. It is his first solo album and I have my open copy to listen to.   
I’ve had consistent good luck at antique malls locally. There’s always a good-sized selection from a number of dealers, who must have no other place to sell. I came close to purchasing someone’s well cared for lifetime collection of classical albums at a dollar a record there once. I found them in the back corner of the antique mall. After discussing the purchase with my wife, I went back the following day and all several hundred were gone. Maybe a dealer got them. That’ll never happen again.
