Just paging through my AudioAdvisor Winter Clearance circular and it would appear that they have a deal on 2 demo units of Nuprime's DAC 9. They are available for $599.91 each.
It has been three years, not such a long time ago that I purchased my exasSound e22 DAC, with which I am enamored. It was one of the first readily available to handle DSD 256 and its voltage switched automatically so I was sold on it immediately. It sounds great too
Anyhow, pretty much the same features which I purchased for $2500 can be available to you for $600, if you take advantage of the above offer. Even at the regular price of $749, thats about one-third the price I paid for my E22, a bit less than that even.
The DAC 9 at any price is a bargain compared to what's out there.
