If it is SS. amp, I would leave on all the time unless gone for extended period of time. The on/off of an amp does more damage then good.
Harm in using a power strip as an on/off switch?
Is there a problem with leaving my power amp turned on and using the power strip to which it is connected as the as the on/off switch? The difficulties I face in locating my components would be eased if I could place the power amp out of reach and use the power strip as the on/off switch.
