I'm in the final stages of building my BII and I'd like to implement USB if possible.
All I can say is I am working on it as fast as I can.

This is an entirely new USB module.

Ok so its a better design same functionality. Is this design about isolating the usb gnd from the signal? I think I have read about how this improves the quality of the signal.

Hi Russ,

Are you working towards 24 or 32 bit depth?

Pure Music is working on 32 bit software applications that they claim the ESS Sabre DACs are the first true 32 bit DACs that can realise it. It would be nice to able try it out.

The module itself will support 32bit (at least for I2S output as SPDIF is inherently limited to 24bit). The only question is will the readily available drivers support it? I will need to test this from the driver end, but there is no hardware or firmware hurdle here.

The current USB module is based on the PCM2707 and is limited to 16-bit 44.1/48kHz material.

The new USB module will be based on an XMOS processor and will reproduce material up to 32-bit/384kHz.

Different in every way.

How about the power supply requirements?

Should I save some space for an extra Placid in my chassis?

Thanks.

NO you won't need any extra power supply.

This board will be bus powered and have only digital outputs.
