Has anyone tried running the AD746 in the headphone amp? It seems like it would do very well.

Don't use the AD746, it is not unity gain stable. But you could try AD712 and let us know how it goes...

Actually, the only safe/trusted way for a new one, is to buy it from Lawrence on eBay, or email him directly and do a PayPal purchase. This is what most of us have done.

Ok. 7 weeks later I finally got my Zero. I ran the optical cable to my Realtek and plugged in my HD650. It doesn't sound so great but it works. I then connect the Zero to my MKIII with RCA cables. I plug in my HD650 to the MKIII and it sounds pretty good...for about 30 seconds. Then the music stops mid song. I don't know what happened but nothing I do seems to fix it. I have the Zero connected to the Realtek through optical, headphones plugged in, nothing else connected and it doesn't seem to work anymore. Any ideas? I've powered everything up and down, redid the cables. Even when I was just using the Zero I had a few pauses in the music so maybe something was going out. I only used it for about 5 minutes. All the lights seem to work and I'm getting light through the optical. I don't have any extra optical cables and the optical connection on my X-Fi doesn't match the cable.

Go into the properties of the realtek audio in the control panel and make sure the settings are correct there. If so, then I would try another optical source to make sure the Zero is working, which it most likely is. Early on, I had issues with my Realtek HD audio built in to my notebook. It would stop start skip jump, and it turned out it didn't have enough CPU cycles for itself. If I waited until the hard drive wasn't running start up things, then it would be ok most of the time. I do remember I had to activate the Optical out in the windows audio settings.

So I read here that Zero DAC Amp > Hotrodded X-Fi Fatality. Is that the general consensus? What if it was Hotrodded X-Fi + iBasso D2 (or Go-vibe petite, or any other similar portable amp) vs the Zero DAC? How much better would the Zero DAC be (I'd have to sell my iBasso D2 if so to get this baby )? This is assuming everything has had opamps rolled, and damn the expense of the opamps

Oh yes, is digital out good for gaming? I think I read somewhere that games can't pass 5.1 audio out through digital? Or is that bologna (or am I supposed to spell it baloney in this case? =\)?

The Realtek digital appears to be working. The sound meter next to the digital out option is moving with the music. Like I said it stopped mid-song and I didn't change anything. I tried it on my wife's computer but it's not entirely obvious if the optical is working. It's lit up but I don't see any options for it in the sound panel.

So I took the lid off and found the Mute and Reset switch. Should I give one a try?

Pressing the reset button does reset the microcontroller which initializes the DAC and the receiver. As does a power up.

There is a LED between coaxial and optical input... if it is lit then there is a valid S/PDIF connection to your computer. But it doesn't indicate that there is any sound.

Which other LEDs are lit?

4 LED all together. One by the optical. One kind of over by where the power comes in and 2 on the smaller board at the front. It looks like the only two not lit are the reset and mute.
