Looks great, will be interested to see how it measures and the price. Especially as their first headphone amp (SGA-1 I think it was?) was a bit overpriced and underperformed (at low impedances). Their second, more budget HPA looks a bit better, definitely price wise anyway. I haven't seen any 3rd party measurements though and there is still some weirdness going on at low impedances with the single ended output having more power than the balanced.
