Check your owners manual as some manufacturers have allowed for this with switchable power modes. I had a Bryston 4b-SST with a switch on the back for connecting the power to a "switchable outlet" (on/off light switch controling an outlet) and it worked just fine. I had the amp behind a entertainment center and it sounds like you will have a similar placement and power use.
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.
