By default the input phono socket "earthy" side (the common connection) is connected to mains earth via the chassis. Adding one of these cables creates another loop, probably harmless, but it won't improve anything. Connecting it to PCB ground connections will guarantee faulty operation. It will sound different, and as I've tried to teach, different doesn't automatically mean better.

For those interested in my references for the earlier article on The Problem With Stereo (and multi-channel amps) please refer to the following:




At time of publication of these journals I was aged 6 and 9 respectively, and only know of them by following the references shown in later published designs, and only being able to view them since David Gleason did the arduous work in compiling the data at American Radio History dot com (https://www.americanradiohistory.com/Scanning-for-American-Radio-History.htm)

I trust David gets more interest than the 2 or 3 readers I get here on a good day. The Internet started for the purpose of sharing scientific documents, engineering being a science, and in searching a book you look through the index, and if a page exists it is in there.

Google on the other hand do not index pages such as these, and so they may as well not exist. I found it difficult throughout my career finding good information, and that looks set to continue for others. I trust somebody is getting the benefit from all this research? (other than copycats that is)
