I've had a CI Audio VDA-1 (with PS) in my system for over 3 months now and have absolutely no regrets. As I've said before, IMO, the only problems that it has in gaining acclaim are 1) its reasonable price raises questions about the high price of so many DACs; 2) it doesn't need to be rebuilt before you can enjoy it.
I don't know why so many want to compare it to the ART/DIO, which seems much more like a DIY electronics project than anything else.
