I turn both my SS Pre & Amp off. If that is what you decide to do then this is what I found out here. Laughing Our Faces Off. This refers to the Amp, L & O = Last ON
F & O = First Off
This made sense to me as my last system, Infinity Kappa 8's with an Adcom 555II amp. This set up for 15 years did the same thing every time when turning off in this way with the volume turned down all the way down. For 15 or so seconds the speakers had a popping noise, then I turned the Pre off.
