Haha, I am glad I am not one of those as I only don't mind paying a little, not a lot more... Having said that, to those people who consider beauty could be priceless, $1,000 more for the C30 over the 6800 is well worth it, even if the Marantz models cost 3X more, they would probably still go for it, we can call them silly all we want.
No offense, if you think you hear that Marantz sound than it works for you, just that you have to know you are listening to the Marantz, because if you don't know (such as blind folded in a dbt test that Harmon and others conducted), then you will not be able tell you are listening the Marantz of the equivalent Denon. Both are facts, that those who believe the Marantz sound is imagined, and those who believe they are real. I say they are silly, only from my standpoint, based solely on engineering/scientific facts, but I know that's not actual silliness because a fact that to those who believe in something, it is real for them. I think can think of how religion works on religious people but I must not go there.
The only things that people often missed, is that one will disappear if the listener does not know which test object is playing, and also that if one believe in it, it is actually real for them. Even on the medical science side, Placebo "drugs" did actually work in some cases, but in those cases, I am sure
@AcuDefTechGuy knows much more about what I simply read from Googling and may tell me I am wrong.
