I saw an interesting thread here: http://forums.stevehoffman.tv/threads/some-commentary-on-vinyl-quality.123380/
The OP pasted a commentary by Classic Records which had specific problems with lacquer brand and silvering.
"...Transcos became noisy as a result of their supplier of nitrocellulose acetate, the material lacquers are coated with, delivering material that was not filtered as rigorously as it had been in the past and chemistry problems with the materials used to make nitrocellulose acetate. Further complicating the matter these problematic lacquers, even when we used hand-selected examples, often had problems in plating during the silvering process, requiring sides to be recut. On a tip from the plating plant, we sourced and began importing MDC brand lacquers from Japan, which for a while, were both quieter and plated more consistently than Transcos...."
I agree that Transcos usually sound v. good. However, there's a post here from concrete man who cited issues with test pressings using stampers made from his cuts on Transcos, even though the test cuts were quiet. Mothers were reported to be quiet, too, but most labs only do spot checks of the groove, so, the issue could have been missed, there. viewtopic.php?f=10&t=4386
Fortunately for Classic Records and others, the issue eventually goes away...for years, it would seem.
Good luck, Tim E.
