Many moons ago, the subject of Classic Records Quiex SV-P formulation being used exclusively on Classic LPs was raised on this forum eliciting skepticism (among other things) from some forum members. Apparently, Michael Fremer wondered too and asked RTI’s Don MacInnis for an explanation. Michael Fremer, from Stereophile, Sep 2003 issue, page 35: Turns out Classic does have a separate vat, and while their pellets’ formulation is identical to what’s used elsewhere in the plant, they are different. During a visit to RTI, Classic’s Mike Hobson noticed someone using a machine called a Pelletron, which RTI uses to treat “regrind” and “flash” for those customers who don’t want to spend extra for virgin vinyl. Regrind is the vinyl from rejected LPs. After the central label area is punched out, what remains is ground up for re-use. Flash is the excess vinyl automatically trimmed from the outer edge of a just-pressed record. The problem with raw regrind is that some of it exists in the form of powder. When regrind is heated to 300°F in the press, the powder burns and turns to carbon before the bigger particles can melt. The carbonized vinyl means surface noise. The Pelletron is used on regrind to remove the static charge, which allows the powder to be easily separated from larger pieces of regrind. So treated, MacInnis avers, regrind is as good as virgin vinyl. Inevitably, static causes some vinyl powder to cling to even the finest virgin vinyl stored in the bins. Hobson asked MacInnis to use the Pelletron on some virgin vinyl and press some records using it, and some with untreated virgin vinyl. Hobson listened and decided the treated vinyl was considerably quieter. It costs more to treat the virgin vinyl, and the cost is passed to the consumer.
