Aura Note - why such low resale?

In my search for integrateds with onboard DAC, I came across the Aura Note. It gets superb reviews. But, I notice that used ones in great condition are going for cheap - under $1000 for a component that is $2400 brand new. That is far greater depreciation than I have seen from other components. Can anybody comment on why that is? It also appears that the warranty is only 60 days - maybe that is an issue.
