Ken.C. is right.
I use an Onkyo Integra M-504 to drive a pair of Thiel CS 3.6 towers. They are 4 ohm rated speakers and reportedly a difficult load to drive. The Big ONK has no problem whatsoever driving the Thiels to high volumes with no discernable distortion and no problems, all day long.
There were many 4 ohm speakers available in the 80's, including Dahlquists, and KEFs - I'm sure there were more, but those are 2 that come right to mind.
Something is wrong with your speakers, cabling, or your M504.
Good luck. But, have you tried M80s? It could just be they drop to low at a certain point for the amp. Maybe your Thiels are a more consistent load.

Generally speaking, vintage 2 channel amps should do well with lower impedance speakers as that is what they were asked of is to power 2 speakers. Like most things, the build quality of vintage units can be superior (though I don't know anything of this Onkyo). With today's electronics there is the tradeoff with features over power and build quality. With modern units it really boils down to features, purchasing power and (increasing) economies of scale of production.

2X6spds....if your running the 504 on Thiels at 4 ohms.
I don't get it. This amp has never shut down until today. With the M80's.
The Polk SDA 1C' run at 6 ohms..i can run them to extreme volume
Its like blow up the speakers before i get anywere near the amp has a problem.
There is no diference in cable or anything..monstercable, Banana plugs....just moved 1 speaker for the other.
Then I'm at a total loss on this... if you can run the Theils at 4ohms..at high volume..and you have no problem. I don't get it.

So, the Onkyo Integra M506, M507, 508, 509, 510 amps are all rated at 4 ohms, some at 2 ohms.
The M504 is only rated at 8 ohms. Wid may be right that the Thiels are an easier load to drive than the M80s.
Audio may be like golf - full credit for luck.

OK...I buy the fact...may not do 4ohms real well
If i buy an Adcom 555 II is there any reason on the face of the planet...why these M80's will not produce really loud sound..like exteme, my ears can't take it..and the power amp would shut down. Would this power amp shut down for any reason at all???? with these speakers?????

Then I'm at a total loss on this... I don't get it. Few people have suggested that there might be a problem with the speaker itself, maybe you should investigate that route before investing on another amp.

Try driving ONE speaker on one channel. Then, try that same speaker on the OTHER channel. Then, do the same sequence for the other speaker.
It might not tell you anything. But it might tell you something.
There might be something wrong in one channel, or in one speaker.
Hook the Polks back up. You might have fried something in the amp when you transitioned from one set of speakers to the other.
I'm VERY surprised that amp is having a problem with the M80's.

OK..I "assume" you mean a number of people have had a problem and i should look elsewere. Like the Thiel, which seems to work with this amp.

I think Bruno means that there might be a physical defect in one of the speakers.
