The impedance of the speakers sometimes depends on the freq its predominantly playing.
The worst offenders are the ribbon tweeters - planar magnetic type like used by infinity or carver. If you had something with that, and its playing a guitar solo, you're basically only using the tweeter and it will easily drift to under 1 ohm and present a capacitor like load to the amplifier.
I have a denon 1610 and a marantz 5002 (the closest to the 2 you have) I like the 5002 a lot more but I never had any of these run that high volume nor have I got any real drifter speakers.
There are also speakers that present like a inductance to the amp though those typically drift a lot less - like not much below 2-3 ohm for an 8 ohm speaker.
I suspect your denon is more efficient than the 5008, hence it wasn't drawing as much from the stabilizer. So your issue may be with the stabilizer ??? I am just guessing. When its over heating, see what component reacts best to a cold air blast. You also have to be careful - hit the heat sink, not the component directly, you can split it by cooling it too fast.
Cool.
