RE: Why does RCA shield connection affect sound?

The point of the shield in the RCA / 75 Ohm format is to protect / isolate low level signals from RFI and spurious noise - such as a 60Hz hum from another device - such as a TT motor, or CD player

lifting the shield at one end can provide a different sound, but it leaves the ground signal discontinuous. (Music is AC, and really needs a 2 wire interconnect) I realize that you have a 'single wire for the return' so you do have both wires -
Yes, there can be capacitance between the center and return/shield, which can be increased but not terminating at both ends-

you are also living in an area where the ambient RFI is low - so it works
That type of wire would not work for me - I'm in line-o-sight to Sutro Tower - the propogation point for most of the FM in SF...(I added ferrite to my phono section 30 years ago to address the preamp issues...
Happy Listening
