And a look around shows a 5 year warranty. What's not to love? Let Sony fix it.

I bought a Sony STR-DA-5800ES A/V receiver July 7, 2014. I have just sent it in for the fourth time because it went into protector mode and will not reset.
It doesn't have a problem playing movies, but when playing concert DVD's it seems that the receiver can't handle the constant higher volume that is put out, and then goes into protector mode.
Considering that this is Sony's top of the line receiver this should not be happening.
I am using Infinity Primus speakers that I bought new the same time as the receiver.The fronts are P363 Towers 8 ohms with a power range of 10-200 watts.
The center is a PC361 8 ohm 10-150 watts. The two rears a P163 8 ohm 10-150 watts.
I'm very dissatisfied and at this point I'd like to be able to return it and buy something differant.
Any ideas or solutions?
