Good Morning, I just recently got a home theater system setup and running it sounds awesome

I have a set of Paradigms 100 v .5 with a emotiva xpa5 amp. When listening to music and playing movies / video games the speakers dont seem to be as loud as they were in the store. Granted the room probably had room treatments and were using a NAD amp and receiver so that may be the case. I usually have the receiver volume at -25 to -20 DB, should I be in fear of blowing the speakers if I go lower say to -13 or -10 DB?
Maybe I am missing something in the receiver settings I have read the manual and am still confused. i have tried many different audio settings Direct, Stereo ,pure audio and that doesnt seem to make them any louder. Maybe someone could give me some insight on this receiver and the settings they use for their setup?
