Why so many DCS for sale recently?

Have you noticed the recent volume of DCS equipment for sale? What happened? Why is so much on the market today? Most of this equipment seems only a few months old? It's very interesting equipment to me and I've considered buying some.
I think people see that upsampling can be done fairly cheaply...such as the MSB Platinum Link for around $3,000. Even the Gold Link III, which I bought for $999, can be easily upgraded to the 24/192 standard. I honestly think people figure, "why do I need this expenseive DCS Elgar, when I can sell it and buy a Platinum Link and put the rest of the money into reference interconnects or speakers or whatever?" The quality of DCS is probably a 10 out of 10, but the MSB Platinum Link might be a 9.5 out of 10. For that small, almost imperceptible difference, people are discovering that they can really save a lot of money by moving away from the DCS.
With SACD players in CD mode, many people feel they get close enough for comfort to the quality that DCS offers for 25% of the cost.
And dcs is not seriously interested in doing the upgrade.
They prefer that the owner sell their "old" units and buy the newest one.
Quick deal.
You know, when units coming back they have to work on already PAID Units, so you can start to think about that...
