Bryston BDA-1 DAC Asynchronous USB?

Does anyone know if the new Bryston BDA-1 DAC uses the same type of asynchronous USB that Wavelength, dCS, and Ayre are now using? I know it has a USB input but it is not clear how they implemented it.
Ask James Tanner over at Audio Circle.
It uses the PCM270X chip I believe. Synchronous adaptive.
