Dbx encoded discs

I had to go to Wikipedia to make sure you weren't making things up. :)

Never heard of it, but it would have been a good idea, IMHO.

dbx discs had to be played through playback software for the recording to play with the right dynamics. It was developed to compete with Dolby B on cassettes but it never really took off. When it was playing with the right playback level it could give startling results but many cassette player manufacturers would not take it up as they could not see the point in having two noise reduction programs. The one you have of the disc is even rarer because you had to buy a processor that went between your preamp and amp or in your tape loop and the processor would expand the compressed signal to give you pretty awesome realistic playback ( for the time ).
 I remember visiting quite a few audio shows and being treated to "Pictures" quite a few times in a night.

I have these three dbx encoded LP Discs:

dbx Recording technology Showcase Series   volume 1
Mark Levinson presents.....
a collection of individual musical instrument recordings and selections from jazz and classical repertoire


BOY WITH GOLDFISH
Heroic Fantasy for Soloists, Chorus and Orchestra
Based on the Hawaiian Legend Paintings of John Thomas
LEE HOLDRIDGE -- THE LONDON SYMPHONY ORCHESTRA


RUTH LAREDO
PIANO
24 PRELUDES, OP. 11     5 PRELUDES, OP. 74      POEM, OP. 32, NO. 1
by ALEXANDER SCRIABIN

I am not into dbx or LPs nowadays.   For some reason I have two of each.  One of each still in wrapping.   Are they worth anything? 

Cheers
