"Even though the ERC and XDA share the same DAC, the reason the XDA sounds so much better is because of the discrete output stage.
In the ERC the design is a straight forward single dif, going to a single stage VAS and output stage.
The XDA on the other hand uses a Dual dif input stage with crosslinked current sources, Darlington VAS stage and Darlington output stages, so the speed and current it can deliver is like night and day different from the ERC.
So as good as the ERC sounded (and to be honest I thought it was amazing), the XDA is in a league all its own."

Actual pics, specs and pricing coming very soon. just waiting on the cosmetic prototype to arrive.
I have an engineering mule, but it is far from pretty. So if all goes well, maybe in another week I can have them for you.
BTW, I don't know if I actually posted what it really looks like or not so here it is.

I spoke to Lonnie about this when I was at Emofest. Lonnie sent me to Eric in engineering. Eric told me the USB only supported max. 16/48.
Post: 11-11-10 @ Emotiva Forum (roadrunner) - link
I just got off the phone from speaking with Eric about the XDA-1's USB ports. There has been confusion as to just what the specs for the USB is really capable of handling. Well, now we have the official confirmation from Eric that the XDA-1 DOES handle 24 bit/192 KHz via its USB inputs. Of course it also handles 16/44.1, 16/48, 24/96, etc, etc. It will output whatever you send it without down converting the signal.

1) L/R Balanced XLRs (all outputs are hgh voltage)

Post at Emotiva Forum (srb):
As has been previously mentioned (and both verified by Emotiva and Analog Devices), the on-chip volume control implementation is an analog resistor ladder, albeit digitally controlled, and doesn't use up bits to attenuate.
(bold added)
I called Emotiva on Friday and asked Vincent that same question.
He said that I should run the XDA at full volume, leaving it at 80, and use the USP-1 to make volume adjustments while listening.
When I mentioned the high gain on the USP-1 he said that the XDA could be set lower if needed, as it was a "lossless" volume control and would not cause any loss of resolution, detail, etc.
So, I have been using the XDA set at about 60 - 70 and I use the USP-1 for volume adjustment.
I do occasionally grab the XDA remote for fine volume adjusments when needed - since one push of the button on the USP-1 remote turns it up or down so much.
Seems to be working well for me that way.
Anyway, based on my conversation with Vincent, I would suggest starting at 80 on the XDA-1 and working down until you find a setting that works best with the USP-1.
