0. Zero. Don't need 'em - CDs sound superb on my system. I built my system for CD input only and it is wonderful.
How many vinyl albums do you own you listen to?
So far I own around 300 vinyl albums all purchased in a last 20 years. Even while I listen to for about 10 albums a week it seems I want to keep adding more and more to my library. I wonder if there is a point when one says it's enough, there is no point to add more as there is no time or an interest to listen to them all. How many do you have? How much time it look to put it together? How many of them do you really listen?
