Hi, looking for some confirmation on a questionable tweak. I have a H/K 520 with seperate pre and amp sections. The two are joined by a seemingly cheap link/jumper made of some chrome plated metal. I replaced the link with a "new" copper link covered in shrink tubing.
I think I made a slight improvement in the sound. Is there any basis to this or is it the physchoacoustic phenomenon? Thanx for any input or comments.
