DAC with ESS Sabre chip, volume, XLR+RCA simult.

The Geek Pulse X does exactly what you ask. It was recently crowd funded for over a million dollars, in case you have been living under a rock ;)

There is a secondary campaign to still get in and buy the DAC, but nothing will be delivered until June this year, and I suspect there will be delays as always happens in these types of projects.

Audiobb, yes it has been confirmed by Larry Ho, chief designer at DaVinci Audio, that the Geek Pulse X will output RCA/XLR at the same time.

All the Geek Pulse range will have a 128 step digital volume control, operating via a knob on the front, or via the IR port which supports the Apple Remote (sold separately).

It seems like it could be a great product. I have one ordered with the upgraded Femto clocks and the external linear power supply option.
