okay, listening to music on my rx-v2500 my reciever seems to get quieter and quieter to where i am finding myself listening at 0 or even +1, and you could probably talk to people while this is going on, not deafening. i can remember when i got the reciever only a couple weeks ago, i would listen around -16 to -20 ish, will the reciever get quieter the hotter it gets? can speakers crap out and get quieter instead of falling apart? i think my speakers are in my sig, they're cheap yamaha htib speakers from two years ago. i cant find a dsp that is louder, so it's not that, just wondering, maybe i'm just becoming deaf

thanks for the help,
