Hello!
I buy 2 months ago Pioneer VSX-520-K + Magnat Interior 5001A and Pioneer Blu-Ray Player BDP-LX54.

From the begining i have a problem whit the sound...when i volume up over 65 , all four speakers crack and make a disturbing sound.
Sometimes when i play music all the speakers fall for 2,3 second same when i volume up over 65!

What do you think? There is a problem from settings or amplifier its very powerfull for the Magnat speakers?

Thank You!
