J_stereo, I had a ARC SP3 along with a Dual 51 and Dual 75. I never even thought of using the switched or unswitched outlets on the back. I don't remember doing any experiments to discourage using them, but perhaps others advised against doing so.
But I certainly do remember little concern about power cords, vibrations, EMI or RFI much less ics and speaker wires. My first special speaker wires were from Bob Fulton and I realized that I had used identical wires on my welding rig while in undergraduate days in a material testing lab.
