Google : Sony SCD-1 player reviews. The first entry will be an outstanding Stereophile review by Jonathan Scull 1999. I have this magazine in my collection and remember reading it circa 1999. Mr. Scull does an excellent job interpreting and reviewing this State Of The Art spinner. Specifically, those 5 filters are examined at length. This will be a starting point.
more to follow,
Happy Listening!
