I own three DAC's.  One sits on the shelf - it's older and doesn't do much for me but the other two are in production.  The Lite tube Dac sits between a Squeezebox III and my Crack  :o (it's not as painful as you might think!), the Stello DA220 from the other digital out on the Squeezebox to my main system.

I'm definitely in for one of Doc's creations!  Sign me up!  I can't wait.  ;D

Does the balanced out on the DAC use the double XLR connectors?  I just picked up an electrostatic amp with the 3-pin XLR inputs and want to be able to feed it a balanced signal.

John just sent me an email saying that he has the SPDIF and the USB inputs working on the latest prototype, just needing a couple more tweaks. Once that is finalized he will get his special digital filter working and hopefully we should have a prototype to audition in few more weeks.

Cool. If that prototype meets expectations would the next step be to move to making it available?

John designs the digital to audio board and does the programming. We do the output design, power supply and packaging. Once we have the board we will be able to assess how much more might be involved in getting it to market.

That can't be more than 30 minutes of work, can it?

Sir you woefully underestimate that amount of work..you forgot the mandatory 15 min food break and 15 min employee ergo stress relief break.  You shouldn't be flaunting state laws  :)

I forget if this has been discussed, but what are the chances the BH DAC will be able to function as a network player, too?

Explanation: I have one main computer running J.River with LOTS of FLAC on it. I'd like to be able to access that FLAC in different parts of the house, via ethernet (or wireless). But I need something at the other end to receive the signal, and to send it to a DAC without compression and gaplessly (that, apparently, is where even great products fail). If the DAC itself could receive and process the signal, even better.

It's a DAC, not a player. It has USB and SPDIF inputs. You would need a Squeezebox or Alix box or an old Mac Mini or other inexpensive player that is ethernet/wifi capable to run into the DAC via USB or coax/TOSLINK.

That's what I figured. Just checking.

I'm taking a short break from slaving away at this and I thought I'd give an update, this is sounding incredible, it is the best sound I have ever heard coming out of a DAC, and it doesn't even have the tube stage yet. I'm listening to an album that I have on both vinyl and CD and am now hearing loads of stuff I have never heard before. This is just plain stunning.

If I had to characterize the sound I would say it's missing stuff: glare, distortion, noise, edginess, grunge, all that stuff just seems to be gone leaving the music in all its glory behind.

Now that I have you all drooling I better get back to working on it!
