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?

"My $5 Sony Walkman CD player outperforms any $10,000 CD player. You just have to know what you’re doing, that’s all."
Apparently, you do not know what you are doing with $10 000 CD player, that's all.

If looking at eBay, there is currently no Sony Walkman CD player that would set you back only $5. Shipping ruins it.
Glubson, apparently I know more than you do. Mystery Solved! 🤗 I don’t mean that in any derogatory way. 
One assumes between now and August 24 the day of the ten DAC blind test the DACs under test will be breaking in along with all the cabling. Or is that too much to ask?
"Glubson, apparently I know more than you do."
I started to doubt it. A long time ago, that is.

Now I know my premonition was correct.
2005- CD player 5000$ = 2/10
2017- DVD super-audio player 500$ = 9/10
2015 Turntable 3500$ = 9.5/10
