How about a sheet of Soundcoat on the under the top cover, in areas where there is clearance? (Soundcoat is a vibration/sound dampening sheet which is about 1/8 inch thick). I believe Michael Percy sells the stuff.
How to reduce CD Transport noise?
my Sony SCD-1 sits at about 10' from my listening spot, and the noises made by the transport, to me, are just incredibly distracting during quieter music passages, particularly in classical music. The noise made by the SCD-1 is no more than that of other players I have heard, matter of fact this has been one of my long-time complaints about CD players. Does anyone know of a product or method to reduce the noise from the mechanical parts of CD players?
