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?

I went from a tube modwright Sony Es 5400 to a Mbl c31. Better soundstage, depth, detail, imaging and transparency. There is a difference if you pick the right 10k player or up! 
Question geoffkait,
Regarding your modded Sony Walkman sounding better than a stock high end player... 
What about a modded high end player?

An older Stereophile recommended list gave only two CD players an A+ rating.

The Sony 5400 CD/SACD player for $1500 and the $100,000 DCS stack.

In their opinion they sounded the same!
