So that Velvet Underground acetate.

it's the Scepter acetate — "Although an acetate version, which was made from these master tapes, was released for the 45th anniversary of the album, it is of a different sonic quality, given the generation loss inherent in an analog copy."

That said, some of the Scepter sessions on that 45th anniversary set are from a "tape source" so I don't know if this will be a marked improvement.
