Has anyone ever convinced anyone else one way or another in the "All AVR\Amps\Disc Players whatever sound the same" arguement?
Not that I'm aware of but then again it is pointless to argue, see above.
One other thing I wonder about, is that people who hold this belief seem to grant a magic exemption for speakers.
Why is this?
I think it's because you can actually see the physical differences between speakers plus they move.
One other thing the OP actually contradicted himself and contradicted the contradiction.
See the title.
Then goes on to say that the Denon DOES SOUND DIFFERENT from his HK.
Then the HK plays the low end with more authority but then states it is too much and that the 80hz x-over point on the Denon is better than the HK.
I guess what I'm getting at is that the OP titles the thread one way and then goes on to directly contradict that statement.
Maybe people should qualify these statements with something like, "they don't sound different enough for me to care about the differences".
And commonsysman, subwoofer refers to the ability\functionality of a subwoofer to play the frequencies below that of the woofer in the speakers.
It's good to see that after years of open-mindedness you've decided to shut the door.
