I converted at home about 200 of my favorite LP’s to MP3 files, using a Sony turntable and a kit bought on eBay. When I listen to that music on my Sansa MP3 player, there is great separation, amazing clear sound and no scratchy blips. There were many steps involved in the conversion process, but none too difficult.
I just get the feeling something was truncated in that conversion. At one point in my younger days (before jet engines) I thought I could probably hear to 25,000 hertz.
I was under the impression that cd’s are limited to 15 Khtz.
