Is anyone using LAST?

I've never had a problem with LAST record preservative messing up an LP, and I used to use it regularly with probably 2000 LPs treated over the years.

However, since upgrading my turntable/tonearm combination and switching to Disc Doctor and now Walker Audio Prelude cleaning solution, I've stopped using it. After cleaning with Prelude, if I add LAST I now hear a slight sonic signature from the LAST that is not objectionable, but that I'd just as soon not have. Still, I've never experienced LAST preservative "messing up" an LP.

Used records I have purchased that have had a LAST treatment are the quietest, and best preserved LPs I have found used.

I've been using it for a few months without any problems. Though this hardly constitutes scientific evidence in favor of LAST, Fremer has a note at the end of his September column, indicating that he's heard from a number of people reporting no ill effects. As I recall, the initial complainant said his LAST-treated records sounded fine on his system but seemed lifeless when he played them on a friend's system that was more highly resolving -- interesting, but would this necessarily indicate that the LAST must be the problem? Seemed to me that he was jumping to conclusions.

I have been using LAST since the early 80's and have had no problems whatsoever. My record surfaces are extremely quiet with no signs of wear - I am a firm believer in LAST.

The person who claims that LAST is "messing up their albums" is either not using it correctly or has a more serious underlying problem.

I used it in the 80s and can tell no difference from untreated albums
