a very fine mist of water sprayed over the record before playing can reduce the harshness of scratches...
I remember many years ago some people advocating playing records wet. Once wet though the record had to be kept wet or the dust in the groves would become mud then dry to the surface leaving the record in a worse state than it was to begin with. I did try it, well you do these things if you're daft enough, but I couldn't see any merit in it.
Excessive surface noise and harshness is a deficiency or fault in the hardware. They shouldn't be intrusive on a well designed and well balanced system.
The only digital radio I've heard is a portable radio someone at work has, and it does sound appalling. What really makes me angry is that these things are heavily promoted under guise of better sound quality when the truth is that it's all about profit and flexibility for the government and the industry concerned.
