yamaha rx-v1400 question

[rootbeer]

<font color='#000000'>I have a yamaha 1400 with a 5.1 setup, I noticed the other day when i crank it up around 80% volume the display gets darker with more strenuous parts of the song, is this a problem of the reciever or maybe of the wiring of my house? if it makes any difference i was listening to pink floyd - money.</font>

&quot;Do not turn your volume control further than the halfway point. If you are doing this, you run the risk of damaging your amplifier.&quot;</font>
