Amplifiers should always only be engaged after the preamp is stabilized. Twenty year ago I blew a set of speakers powering both at the same time.

My current caver amp mutes for about 10 sec after power on and my monster power center holds back amp power for another 10 sec after the 970 signals it to turn on the amp. I never get any start up pops!

Watch out for clipping it destroys speakers.

But when is the firmware comming out of Beta it is better but still clunky
