I just contacted Kingwa and I'm ordering one. For me, it's the right item for the right price at the right time. It appears to have the exact same output stage (as Kingwa basically says in the description) as the Phoenix but it just doesn't have the separated, dual mono power supply and the screen/remote control system. I'd love a Phoenix but it'd really put me in the hole money wise. I can sell my M3 to cover most of the cost of the Roc.
Check out the Roc:

Compared to the Phoenix:

Some subtle differences, where that metal divider is in the Phoenix on the Roc there's some power caps apparently, and there's the power supply nestled in on the Roc where the control unit circuitry is (where it receives the signal from up top). Anyway I like the price and the form factor, it's going to have similar qualities to the Phoenix in sound although it is not as "balanced" as some balanced amps are, not having a dual mono power supply that I can surmise. Anyway, I'm talking with Kingwa about it to get one.
