The V3 is fine and still sounding glorious. One small thing - there is a soft pop that appears at the first flow of signal at the beginning of each listening session. It sounds like the DAC is almost in a ready state and is fully activated (and remains so) when a signal current flows. It is not anything powerful enough to be destructive but I'm curious if anyone else has noticed something similar - or if that's in the design.
Seems like your chip "de-mutes" audible, Bob. I see Doede found a way to lure us to his designsHi Doede welcome to a thread about a good sounding DAC.
sorry, wrong thread
I did not wanted to hike this thread, sorry, I deleted the post
No worries , we are in another segment Doede. I was just thinking you finally saw the light and had built a Subbu V3 DAC It can be built for just a bit more than the price of one of the needed output caps for the DDDAC 1794. The DDDAC 1794 should sound better but I never heard one. Keep up the good work.

Could that indicate a construction error on my part, or just the nature of the system/circuits?
I don't know, my telepathic capabilities have somewhat diminished with the years. I do recall you have an earth/GND/PE problem that needed to be solved. If that problem is still there many strange things can occur. Tried to found out but you did not reply then. I am sure you do have a problem in the house wiring or the PE connection of your gear.
The ES9023 de-mutes but I never found it something irritating/annoying/disturbing.

STOP BEING so JP and answer my question please Should I be looking for something to fix?
Edit: OK, as I said it is a small thing. Just wanted to make sure it wasn't something that could grow into a real problem.
Edit: Edit; We are playing post tag. All the grounding problems have been solved and they had nothing to do with the V3.
In the U.S we use JP as both a proper noun and an adjective.

Never experienced this with the V2.6 or V3 DAC. It must be something specific to your system or build. Can you remind us what source you are using to feed the DAC?

Hey Gary, It's really not a big problem specially now that I understand there is an embedded mute in the ES9023. That's exactly what it sounds like. Just wanted to make sure I hadn't fried something during the build that could lead to problems later.
This is truly TMI, but I'm using BNC from a PC and sometimes there is a noise when the windows drivers activate. What attracted my attention was those times the source had been on and stable, but for any given reason the DAC was taken out and then put back in (or power cycled). That little noise appeared at the head of the next play. That does sound like an internal mute release activated by a current - so I'm satisfied.
Thanks

My work requires me spending a lot of time on a computer. Convenient to play the files that are on there directly using Foobar 2000 with a nice DAC or sound card. It can and should sound great with minimal hassles. However, this DAC is probably not the right project for this type of application
Another Sonus for my office with a nice SPDIF DAC would be nice but the budget dictates spending the money on the "main" system.

The joys of computer audio. More problems than solutions
You are relentless.
"Wha Cha Gonna Do When Da Well Runs Dry" ???You can pair Subbu DAC with a http://www.diyaudio.com/forums/digital-source/236028-xmos-dsd-384-khz-32bit-usb.html , at least this is my plan.
Another DAC is singing right now!
This is my first DIY dac and: it has been difficult but satisfying
It didn't work the first time, so I was worried for Q2 After, I checked the voltage on ES9023 and WM8804 (thanks atapi!) and everything matched within 5%
Finally, it was a dry joint on wm8804 pin 2 (the sw mode pin, if I'm not wrong)! After that, it started to play
Thanks to JP, Subbu for the design & GB. Thanks to Phil for the parts GB.

An externally hosted image should be here but it was not working when we last tested it.
Sure, a higher voltage rating is fine. Is it a 1uf cap? The value isn't too critical but I'd suggest at least 0.1uf and JP recommends 1uf.

x7r for c17
I have several extra values: 1uf/50v, 1uf/10v, .1uf/25v. I'll use the 1uf/50v since that seems to be favored by everyone. I have a second board and plan to try other upgrades. Do you have other recommendations at this point? Maybe I should pose that question on your upgrade thread. Thanks, Gary.

One more SB Dac to sing
I just finished the dac and hook up to the CDP at the moment because I don't have a USB to SPDIF converter yet. The pads for the Q2 were tight and the WM8804 needed to be patience, dial in the correct soldering temperature and good quality of wick to remove excessive solder on the WM8804. Thank you JP and SB to make this GB happen.
By the way, anyone can recommend a decent USB to SPDIF converter?

Just thought I would post a pic of my completed DAC. Fitted into a Hammond case (just).
Sounding superb from the off, but I have not had a chance to do any serious listening yet.
Out of shot to the bottom left are the input (BNC) and output (phono) jacks.
I used a combined switched & fused IEC inlet - A tight fit as can be seen.
I'm not sure how to post an image - If someone could explain please - But here is a link to Flickr...
