I gotta run, but just wanted to give an update. I finished building my DAC today, and it works. I have it hooked up to my SqueezeBox. I'll give more details later. But here's some pics.

Thanks! The sound is promising. The setup is not ideal, as the negative rail was not working, so I had to connect a second power supply. I think I must have burned the LM337. For my next build, which will be intended as a reference, I will use AD1896 and PCM1794, and also AD8610 for the op amps. But, so far, even this prototype sounds good to me. It's more "crisp" than my previous DAC, a TDA1543 NOS DAC made by Derek Shek, but I expected this to be the case. I liked the Shek DAC a lot. I need to listen to my DAC for several weeks to determine whether I will make a permanent change. If the perceived increase in detail becomes fatiguing, then I may switch back. Still, it was great fun to do this project.

Well, I said I'd give some more details, so I posted a bunch of pics and more technical details of the DAC design on my website.

great ez, it's a lot of time i follow this project, and the only thing i don't like are those smd resistors...:D i think i will keep most of your project, just change the dac and opamp and see what will come out...otherwise, great job mate!
