Yes..as mentioned above by other members amp ON last..Amp OFF first..remember to mute all components first also, just as a precaution.
Eldartford- I had two of those ACE-515's at one time in my system of several generations past. They were great before they both became senile and wouldn't turn on or off at times!(old age)..I was also concerned that they introduced phase shift that degraded the sound, although I didn't have such a great system at the time to tell the difference! -Enjoy! :)
