Also with me is shielding problems in the form of noise exhibited by another source. Unfortunately, I noticed this only after the return period because I had come later to rewire my new system. I have long experimented with many new connected - at the end there was only the recognition that it is precisely the new "Silver Line Digital coaxial cable were" what the untolerablen noise at least for me "promoted".
Now I have my old (shorter, unhandlicheren) Oelbach cable connected, it's all in sound technology in order again. "Silverline" cable I will no longer buy.
