A VPI cleaning, LAST treatment and MoFi sleeves for every LP, since 1981. Stylast stylus treatment before every listening session. Even the vinyls that were used daily for demos at my shoppe, still play sweetly as day one.
LAST record preservative improves the sound
Seriously. I just applied it to 50 LPs of various quality recordings and genres and in every case there was a subtle but noticable improvement in clarity, especially in upper mid-frequencies and a little less in high frequences, but also some improvement in pace and dynamics. The records were very clean before the application, I did not clean them again prior to applying the LAST. Mostly original Japanese vinyl from seventies but not only, vinyl condition varies from NM to VG. I am impressed. This confirms what a man from the Needle Doctor said when I asked him.
