Records that sound better when played on vinyl

However, my mum who is what can be considered an Audiophile is a member of B&W's Society of Sound (http://www.bowers-wilkins.co.uk/display.aspx?infid=777) and recieves a variety of music via their download service and is very impressed by the quality.

She has well over 30'000 records and has spent a small fortune on her equipment and is now debating whether to downsize and go fully digital. I found an interesting method (http://www.audioxpress.com/magsdirx/ax/addenda/media/staggs2737_highres.pdf) which I am going to try when I go back home next month.

that's very interesting, it's also very unusual to hear of a female hi-fi buff, it always seems to be geeky blokes.
