...

Q (TonyMc): "So would putting the XDA-1 between transport and USP-1 negate the sonic improvements of the XDA-1?"
A (Lonnie): "It won't negate the improved sound, but as good as the line stage is in the USP, the XDA by itself is way better."

Emotiva XDA-1 digital-analog converter (DAC)
Cost: $299.00

Specifications:
(pending)
From Emonatics - http://emonatics.com/XDA-1.shtml
(unconfirmed)...
Inputs (both)
1) AES/EBU
2) Coax Digital
2) Optical Digital
1) USB (Should be PC & Mac Compatible)
-- Post: 10-13-10 @ Emotiva Forum (link):
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.
Outputs
1) L/R Unbalanced RCAs
1) L/R Balanced XLRs (all outputs are hgh voltage)

Triggers (automatic on/off for amplifiers and XDA-1 itself)
1) 12v output trigger
1) 12v input trigger

Analog Devices AD1955 DAC, with 384k oversampling, and 1V rms (7V peak for extended dynamics), 24-bit, 192 kHz Sample Rate PCM Audio Data, 120 dB SNR/DNR (not muted) at 48KHz Sample Rate (A-Weighted Stereo), -110 dB THD+N (0.0003162%)
Burr Brown buffers coming out of the DAC
6 fully discrete output stages
Selectable inputs
Segmented power supply

XDA-1 Manual

Features:
- headphone jack
- volume control: digital & global (for all inputs)
--- therefore, turn volume to MAX for use with pre-amp ????
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.
- 6 discrete output stages
- selectable inputs
- segmented power supply

Other info:
- 1 RU high
- old name was XDC-1
- Lonnie (@ Emotiva forum):
"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."

Future:
- "At this time I am just working on this one. The baby version is down the road. "

---------------------
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.

---------------------
Specs are pending but previous comments...

- estimated cost - $300
- 1 RU high
- old name was XDC-1

I've been watching the thread over there for a while and am looking forward to hearing how well it performs. I've just always used my receiver for DAC but am interested in a standalone DAC. I wonder what I've been missing

I am no DAC expert, but I think the answer is "it depends".
The HRT MS DAC I added to my laptop made a difference.
I think the major variables are how good your source(s) are, the current DAC, and the rest of your audio chain and speakers.

Full specs & product sound like they should be available soon.

XDA-1 DAC update - close but delayed

From Lonnie (admin) at Emotiva forum today:
Link

"Well I have been a little remiss about getting you up to speed on the XDA and I am sorry.

We got in the final cosmetic sample and have been testing and listening to it extensively. First off let me say that the sound quality is unlike anything else we have done before. It is really something special. The discrete output stages in the XDA are in a league of their own. The discrete output stage we did for the ERC and USP as good as they are can’t hang with this thing. The depth and detail in the music is so deep and accurate it is difficult to describe, so I have no doubt you will love it once we release it.

Now the bad news. We placed the XDA on top of the ERC (we were using it for a transport) and while we were listening to it, we just couldn’t get past the fact that the cosmetics didn’t match and it just didn’t look right. So we have redesigned the front panel to give it a more family look. Unfortunately this will delay the release a little longer, but all the electronics are solid and fully check out. So hopefully this won’t delay things too much longer because I know many of you have been waiting for a while.

I am sorry about the delay but we want you to enjoy the whole experience of the unit and have it match up with all the other gear, so hang in there it is coming."

I personally think the new design is much better than the previous ones. It's great to have an update on them!
Yeah, it looks cool.
Good to have another DAC option (although there are a lot) at a low price point.

Now just need some product, reviews, posts...

With its unique topology, the Music Streamer provides a completely isolated path between the computer and audio system. No more audio contamination by the computer; your music will always sound its best. There are no external power supplies to worry about because the Music Streamer derives its power from the USB buss while completely regenerating power for all its internal circuitry using a sophisticated set of proprietary circuits.

Operation is simple: just plug the Music Streamer into any USB port on your computer and the Music Streamer will install itself and be ready for use in a matter of moments. Connect the other end of the Music Streamer into any analog input and you are ready to stream high quality computer based music. Minimum System requirements Windows XP service Pack 3, MAC OsX 10.3 or newer. Not all MAC Mini's have enough output voltage to power the Streamer in some cases you'll need a powered USB Hub.

The Music Streamer provides full support for applications such as iTunes™, Windows Media Player™ Rhapsody, Napster or anything else! Direct to your home entertainment system, with a level of quality never before possible. You can also use the Music Streamer to listen to internet radio or other music subscription services such as Rhapsody™ or Napster™ in high quality through your Home Entertainment System, Television or Stereo system. High Resolution Technologies Music Streamer, the product for tomorrow, is available today.

i will admit i am not up to speed on the DAC players
So what are the main things/specs/etc to look for
is it the greater the value of the specs the better or is it the lower the better. :crazy::crazy::crazy:
What are Quality components and which are the ones to steer clear of??
anyone care to educate??
:huge:

Me to, I'm not sure what an external DAC is for other than higher quality sound.

XDA-1 DAC "final sample"

From Emotiva thread post:
Link

"From the podcast: "The final sample, with the revised cosmetics of the XDA, is shipping tonight. Yeah!"

Which I assume means it's shipping from China to Emotiva. So, it's getting closer, but not that close."
