I thought Z-material continued in use long after the letter had disappeared from the
pressings, since there are abundant examples of very quiet Victor pressings right into
1940 (until the introduction of drop automatic album sets, lower prices and miserable
quality shellac and the end of worthwhile record collecting as we know it). I've also
turned up the odd z-set that was very noisy (Verklarte Nacht, Ormandy)..could this be
from a set of z-stampers being used on a different mix?
