Help rotel pops when turning on and off


Why!! what can I do? just got it used, when on it sounds great, its not a loud pop but I can see the woofers moving, is it going to hurt my speakers I know it cant be good! Its an older rotel, probably been sitting awile but super clean. its an RA-930AX

well thank god theres no humming!!!! Thats crazy though! I have a cheap 40watt sony reciever from 1994 that doesnt do that!! What the heck!As expensive as this stuff is in comparison to what is availible at big box stores you expect superior design and sound!!!
How efficient are your speakers? Rotel gear will do that pop and its normal because of how the design it to sound good. If you think that pop makes your reciever better you are sadly mistaken........BTW I never turn off my amps so leaving them on is another good idea.
Well i noticed it on a pair of energy towers with 91 db sensitivity. here another thought, its a low power amp, thinking about 30watts a channel , I had to turn it up well above halfway to get to a listening level im used to, is this bad for the amp to do this a lot?
