Here ya go. Sorry for the delay, the boys called me out for a fishing trip.
I did do some A/B testing and they sounded the same to my ear. If I was really splitting hairs I might even say the iFi had a slightly blacker background but I wouldn't be comfortable claiming that 100%; there was probably 30s or so between the switch back & forth. I did also try the different voltage settings on the Hypsos, couldn't notice a difference between them either. I think the Hypsos (or any PSU) benefits the OOR (an amplifier) a lot more than it would a DAC.
Going one step further, you could even buy another iFi to power an OOR and still save money
The all-Ferrum stack does look nice on the desktop though, mis-matched LED's kinda bothered me but I'm sort of OCD about that stuff. I just disabled them.
