SOURCE: Audio glitch on Marantz SR-19
It's probably not heat due to the Marantz' large frame and heat-synchs.
This could simply be a mismatch of impedance. The amp is 120w per channel, so make sure the speakers can handle this. Check the impedance (ohms) of the speakers and the amp as well. Clipping can be caused by overpowering the speakers, which could damage the speakers in the long-run.
If this is only from 1 source- (i.e.- Blu-ray player or cable) then it could be digital clipping.. This Marantz can decode 96kHz PCM or normal Dolby Digital & DTS. If this is a Blu-ray it may be streaming 192kHz PCM... (but most likely the Marantz will not even attempt to play that audio)
I hope this helps.

Most likely you have a speaker short, you need to check the ohms on each speaker disconnected from receiver if they are 8 ohms they should be close to that on the meter no more than a 1 and half ohm varience to what the speaker ohms says on the back. If they are ok you need to disconnect speaker wire from receiver and check for a short in the wire by connecting ohm meter leads to ends of the speaker wire you should get no reading if the wire is good. If this is all good you have a bad output transister in your receiver, but i dout this is the case because these transisters normally short to ground and blow a fuse. Hope you solve your problem good luck

my friend has the same problem with an SR 4001. the tech said it was an internal fuse soldered to the board. the display showed an error code that clued in the tech of the problem. I am trying to find the fuse on the board, and trying to get a value(Volts-amps) of the fuse
