A very interesting device.
I also had the opportunity to hear a demo (with state-of-the-art system) in Milan at the hifi show, and I spoken with the designer.
"Inside the case" there is a micro, a two quartz precision oscillators clock ref, and a s/pdif interface.
The "devil" is in the proprietary driver, it's able to release from USB clock and to use USB-2.
Yes, it's really 24/192
No more PCM 270*, no Tas1020, no more ASIO drivers.
And driving it is a very easy task for a PC, so that even a Intel Atom is enough.
And yes, the sound is really OK.
I think that soon we will get wind of it.
And no, the designer is not my cousin
Ciao!
