I own Michael Jackson's Thriller and ELO's Time on CBS half-speed master vinyl and they sound excellent even on my modest Technics SL-5 table with Grado cart. I cleaned them at an audio shop (DB Audio, Berkeley) years ago on their commercial-duty machine (VPI?) using LAST cleaner/preservative so they are dead quiet. Would love to spin them on a high-end analog system some time! -jz
