First of all, I'm new to most of this stuff, so please forgive me. I have a relatively new AVR 520 connected to JBL S38s for the front, S36s for the rear, and an S-Center. I've noticed that the 520 doesn't seem to have enough power -- what I mean by this is that I can easily turn the volume level all the way to +10 on most sources, and while it's relatively loud (and I would usually not listen to anything at that level), it seems like it should be even more powerful. And interestingly, while the volume scale on the 520 goes from -80 to +10, starting at -80, I can't hear anything until I'm at about -29. What's the point of the lower levels if they're not audible at all? I sometimes listen to music and some DVDs in the range of -5 to +2. This seems a bit weird that I'm almost at the max volume with a receiver like this. Is this all normal, or am I just an idiot who hasn't set up the receiver properly? Thanks.
