I have two home stereo amplifiers in different rooms. I tried connecting Zone 2 with (the other room) with 50 feet of RCA cable and noticed there was some noise (I live right next to an AM radio tower and my house has some pretty bad electrical wiring).
I then switched to what I thought was rather crappy 50 feet 3.5mm TRS (unbalanced) and the noise went away.
Has any one noticed that TRS is better than RCA? If so my question is why don't home receivers/amplifiers just use TRS instead of RCA?
