According to Paul McGowan, this DAC is a game changer - certainly at its price point, but potentially in absolute level as well. It beat the EMM Labs (3x price) handily according to him. I am intrigued enough to give this a whirl, get my hands on one once it ships, and do a shootout against my MSB stack (6x price). I'll keep the PS audio if it as good, give or take a few percent.
