Promo Pressings

Are old vinyl "promo pressings" (for D.J. use) sonically superior than their commercial counterparts, or is the only difference the white label marked "Not for Sale"?
No question the first promo copies are the best sound of all. Most of the time these are mint condition when found.
i collect promo pressings, among others, for reasons already noted. the more recent promos are pressed with "quiex" labels. the ones i treasure most are those with interviews between tracks. the very best "graceland" version i own was originally produced as a radio promo for the album, with narratives by paul simon between each cut (it's a 2-lp set). -kelly
Just want to strongly second Kelly's mention of Warner Bros' use of Quiex pressings. (did any other label use Quiex?)
Two recordings that blew me away sonically AND MUSICALLY, that I have on Quiex, were;
Donald Fagen: The Nightfly
Paul Simon: Hearts and Bones
Both early digitals(amazingly) from 82, 83 era. I treat those 2,on Quiex,like fine wine.I preserve those pressings for a special listening occasion. Quiex was high end right from the source. Now if I could only find a Quiex of the debut Rikki Lee Jones, or Little Feat's, Time Love's a Hero, I would, well you know!!........Frank
frank: i don't have a quiex of rickie lee's eponymous album but i do have a 10" promo quiex of "girl at her volcano," which includes "under the boardwalk." never heard a better exemplar of "dynamics." another quiex promo to look for, BTW, is laurie anderson, "mister heartbreak." is there an lp you're especially looking for that might cause you to part with you quiex "hearts and bones"? -kelly
Kelly, I wish I could find a list of just what was produced on Quiex. If for any reason I stumble onto another copy of the Quiex "Hearts & Bones",its yours. (I am sure you are aware of just how great this underrated LP is. The "Late great Johnny Ace" cut is a masterpiece!).
I am familiar and also own the "Girl at her volcano" LP but don't have it on Quiex. Ultra rare to be sure. The Rikki Lee interpretation of "Under the boardwalk", is indeed a gem, and the most interesting version of this great Drifters classic. Now if I could only get the desire back to turn on my system. After the week from hell, I just can't do it yet........Frank
