What Sonically is the Difference between a $1,500 CD Player and a $10K-$25K One?


I realize opinions may vary, but if I could give an example of two CD players perhaps someone can give me their thoughts on the cost benefits of either one? What would be the difference in your opinion between say a Cambridge Audio Azur 851C CD Player and the Gryphon Scorpio S CD Player? And are the difference truly audible or more technical and rather indiscernible through human hearing?

In general, what makes a CD player (other than build components) 10x more costly than a decently built one other than features?

2005- CD player 5000$ = 2/10
2017- DVD super-audio player 500$ = 9/10
2015 Turntable 3500$ = 9.5/10
Glubson, and I mean no disrespect, you don’t seem to know anything. Am I being too harsh? 
geoffkait,

As usual, you are being incorrect. "Too harsh" would be too harsh of a description.
Look y’all I heard the solutions 540 after I heard the luxman d06 and the Luxman was no slouch but the soulution player is the best I have heard in my life. I think it’s 35k. It sounds analog, natural, open with big images. Lots of air ,space, timbre. However you have to have great equipment as well in the rest of your system. I suspect some commenters may have not experienced the mid to high end systems.  You can’t out this player in a 10k system and reap its real benefits. I have owned a 10k system and it was good but as I grew in the hobby I was able to get a 40k system that now allows me to hear more detail, space, air and dimensionality. Your gear has to be able to assist in reproducing the great sound benefits. 
Nobody mentions that a person MUST know how to listen and to be ABLE to hear.  I am fortunate that I still can do both.
