Unless you have a lot of free time, the effort is not worth the result. Great analogue sound is never reproduced from a CD/ Best to keep the vinyl and a top rated turntable. If you want to hear what a top rated conversion of an lp to cd/hard drive would be look into having just one, your most listened to lp done by the many professional services that do just that. Then compare to understand what if any benefit you get.
Converting Vinyl to digital
I saw an interesting unit in JC Penny's today. For $99 you get a record player and you can feed your LPs to either a computer or burn a CD. While this is probably not the best choice for an audiophhile, I am curoius what is out their that will do this to satisfy at an audiophile level.
