I think I've heard this effect on another Candide, source from a French Andre Charlin LP of Darius Milhaud conducting "L'Homme et Son Desir" in 1962-66 or so, but the Vox cut would've been made years after that.
Certainly the Charlin would have been a non-standard kind of stereophonic recording, like the Japanese music title. Really quiet passages almost disappear, loud ones get very loud. I agree that I haven't encountered anything like this on Vox Lps that Vox itself recorded - they usually sound great if you have a good copy (and pressing) to work with. Some Turnabouts pressed on thicker vinyl tend to have a "swish."
So perhaps one should keep the source in mind when utilizing records that Vox imported from other companies.
