Why do Asian looks for old Wadia CDP at high price?


I recently sold my Wadia 861 for a Vietnamese at unbelievable price.  The question keep popping up on my mind why do Asians (Vietnamese) interested in the Wadia CDP too much even at very high price. Many nowadays CDP has better quality with up-to-date technologies on sound distortion deductions.

We have been used Wadia for around 2 decades ago and it's time to put them on retirement but they treat as treasures. I was so surprised about that. Wish I could have more Wadia CDP to sell to them in order to make some extra bucks.

i heard many years ago that the japanese back in japan likes the older stuff. i heard that 'jbl' makes the 'paragon' speakers for them because they like it. also heard that they pay big bucks for the classic american cars too!
I have owned my Wadia 861b since 2003 and she is still running strong.  Any ideas how much longer it will last and what is the most likely thing to fail.  I guess once it fails, I have a big chunk of worthless silver metal at that point (albeit a beautiful one).
Perhaps Christiaan can shed some light on the subject:

He did.
The Wadia 512 which he loved uses old R2R Multibit dacs, the last ones made without going discrete like others are today. Burr-Brown 1704 DACs.
Today because Wadia used the ESS Delta Sigma dacs instead of going discrete like MSB and others, they don't seem to hold center stage as much.
MSB went for doing discrete R2R Multibit after the last R2R chips ran out and they seem to have the center stage more than Wadia do now.
