My opinion is that the Sony SCD-1 is a classic piece of audio gear, and from a re-sale point of view you're better off keeping it in it's stock form.
Yes, there were (are) many folks who modified their SCD-1 players, and the results were supposedly really, really good. But, having the advantage now of looking back at the SCD-1's place in audio history, it seems a crime to mess with it.
