Ha! I missed this little box back then. Let's get this straight: It is 1995, CDs have been out for almost 15 years, LPs sales are pretty much gone and the age of the Internet has just begun.
So, there appears a scratch remover device for over US$500.00 and Marantz expects it to sell? Tall order.
I, too, wonder who and why someone would have purchased one......
BTW, check other devices like the the Burwin Dynamic Noise Filter systems of the 70s for other all-analog approaches to the same problem. There were others, too, but Burwin got pretty close 2 decades prior to Marantz!
Cheers,
